Abstract
This study investigates the phytochemical composition, antioxidant properties, antidiabetic potential,and alkaloid profile of Syzygium aqueum fruit extracts. Phytochemicals screening identified various bioactive compounds, including tannins, phenols, flavonoids, alkaloids, glycosides, terpenoids, and coumarins, with reducing sugars detected exclusively in aqueous extract. Antioxidant activities were evaluated through DPPH and FRAP assays, showing that antioxidant efficacy improved with increasing concentrations and longer incubation periods. The total phenolic content analysis further highlighted the fruit’s potential as a natural antioxidant. The antidiabetic effects were assessed by analyzing α-amylase inhibition and glucose adsorption capacity. Among the tested concentrations, the 15 mg ml-1 aqueous extract exhibited the highest α-amylase inhibition, suggesting strong antidiabetic potential. Further analysis of the crude alkaloid extract, confirmed through UV and FTIR spectroscopy, revealed prominent functional groups, including C=O, C–H, C=C, C–O, and C–C, suggestive of a complex phytochemical profile. These findings underscore S. aqueum potential as a valuable source of natural antioxidants and antidiabetic agents, with implications for functional foods and phytomedicine targeting oxidative stress and blood sugar regulation. This study supports further in-vivo investigations to validate these effects and explore the specific mechanisms of action.

Composition and Impact of Steel Plant Solid Waste on the Formation of Vigna radiata (L.) R. Wilczek Root Nodules

By: Subhasmita Panigrahi , Pritikrishna Majhi , Sanatan Padhan

Page No : 29-35

Abstract
The mung bean, or Vigna radiata (L.) R. Wilczek, is a legume plant that belongs to the Fabaceae family of peas and is cultivated for its edible seeds and young sprouts. Mung beans, like other culinary beans, are rich in protein and dietary fiber. They are also a good source of iron, potassium, magnesium, and several important amino acids. The nitrogen-fixing bacteria found in nodules on the roots of mung bean plants,like those of many other pea plants, contribute nitrogen to the soil. It is now crucial to use metallurgical solid wastes, like steel slag, in agricultural operations in order to boost crop yields and lessen the buildup of these wastes in the environment. Solid waste of steel plant contains nutrients like CaO, MgO, SiO2 and compounds such as FeO and MnO. Some researchers have studied its utility in agriculture. As molten steel is separated from impurities in steel-making furnaces, steel slag, a by-product of the steel-making process, is created. The complex solution of silicates and oxides that forms the slag when a liquid melt is cooled and solidifies. Utilizing steel slag in agriculture has both financial and environmental benefits. In this study, mung bean (Vigna radiata) was cultivated in clay pots, and varying amounts of slag from the Rourkela Steel Plant (RSP) between 5 per cent and 50 per cent of applied solid waste was on the basis of weight of waste in relation to the amount of solid added to the pots were applied individually.Minerals contents in the solid waste can be absorbed from the solution which are available in soluble or ionic form. After seven days, the number of root nodules on Vigna radiata plants cultivated in various containers was determined. Plants from the more heavily treated pot were found to have lower root nodule production than the control. Nonetheless, there is no statistically significant variance in the production of root nodules. Thus, it can be understood that steel plant slags do not impair Vigna sp. growth at lower concentrations but have an impact on plants at greater concentrations.

By: Athira S. , Sreeranjini S.

Page No : 54-60

Abstract
Streptococcus pyogenes is a Gram positive bacterium that causes infectious diseases like rheumatic fever, Rheumatic Heart Disease (RHD) etc. which can be prevented only by long term penicillin usage. Emergence of antibiotic resistant bacteria and side effects of long term usage of antibiotics are posing a serious threat to mankind. Plant based alternatives are considered as an efficient remedy for this. Current study was aimed to evaluate the antibacterial and antibiofilm activity of the leaf methanolic extract of Sphenodesme involucrata var. paniculata (C.B.Clarke) Munir, an ethno medicinal plant against Streptococcus pyogenes. The antibacterial activity was analysed by agar well diffusion assay and antibiofilm activity by in vitro anti-biofilm assay. The extract showed a better inhibition zone at 100 μL and showed a potent anti-biofilm activity in a dose dependent manner with an inhibition percentage of 97.1 at 1000 μL concentration. The results suggest that the usage of this plant can be considered as a defence against S. pyogenes with further in vivo analysis.

By: Leoris Malngiang , Md Sayeedul Alam , Sohini Deb , Hamebantei Mawkhiew , Abhishek Rana , Gargi , Hiranjit Choudhury

Page No : 61-74

Abstract
Ilex embelioides Hook. f. is a small evergreen tree, endemic to Arunachal Pradesh and Meghalaya, India. This species is listed as vulnerable (VU) in the IUCN Red List, and is considered to be extremely rare.It belongs to the genus Ilex under the family Aquifoliaceae. Traditionally, the species is used for the treatment of cold, cough, tuberculosis and its bark is used as natural black dye. The plant has been exploited heavily for its timber posing threat for the survival of the species in the wild. Under natural conditions, seed germination of the species is low and vegetative propagation is also slow. Thus, mass propagation through in vitro culture methods is important to compensate for the poor regeneration capacity of the natural populations of I. embelioides. With this perspective, shoots were induced in vitro from apical and nodal buds of I. embelioides on WPM and MS media supplemented with 2μM of BAP.Out of five different basal media tested (MS, ½ MS, ¼ MS, White’s medium and WPM); WPM was found to be the most effective for shoot initiation, whereas both WPM and MS was effective for callus initiation. Different plant growth regulators (BAP, KN, IAA and 2, 4-D) at different concentration (2μM - 12 μM for nodal explants and 0.1 μM- 2μM for leaf explants) were used for the induction of shoots in different proportions. The combination of BAP (8.23 μM) and Kinetin (5.11 μM) on WPM was found optimum for shoot elongation from apical buds with minimum browning of the explants. Whereas, combination of BAP (1.11 μM) and 2, 4-D (1.25μM) both in WPM and MS resulted in optimum and healthy callus formation from leaf explants. Half strength WPM and ½ MS were supplemented with different concentration of IBA, NAA and IAA for root induction. 71.11 per cent of root initiation was achieved on ½ WPM with 9.08 μM of IBA, but no rooting response was obtained in other combinations of plant growth regulators. Acclimatization and final establishment of rooted plantlets were done in potting mixture of soil, sand and perlite (1:1:1 v/v/v) with 60 per cent survivability rate. SPAR method was employed to confirm the genetic uniformity among the randomly selected in vitro plantlets raised from young mother plant (YMP) and mature mother plant (MMP) explant sources. Results revealed that young plants are better choices for explant collection with regenerants from YMP showing 4.37 per cent while MMP having 7.69 per cent polymorphism with that of the mother plant. Minor variations among the regenerants especially with YMP explants guarantee the safety and efficacy of the micropropagation procedure for the purpose of producing true to type genotype for species recovery and conservation of the species as well as ethnomedicinal uses.

Pharmacological Studies on Some Medicinal Plants for Bone Disorder

By: Varuna , Devendra Pratap Singh , Alok Tripathi , Divya Singh , Rajiv Gupta

Page No : 75-86

Abstract
The study presents a detailed analysis of the fingerprint profiling of ethanolic extracts derived from two well-known herbal plants, Curcuma longa and Moringa oleifera, using Soxhlet extraction. The extracts were comprehensively analyzed through Thin-Layer Chromatography (TLC) and High- Performance Liquid Chromatography (HPLC). These analytical techniques revealed distinct fingerprint profiles, identifying bioactive compounds such as curcuminoids and quercetin. To evaluate the osteoprotective effects of these extracts, an experimental study was conducted using a fracture model in Balb/c mice. The mice, subjected to a drill hole injury in the femur metaphysis, were treated with oral doses of the ethanolic extracts. The treated groups demonstrated enhanced fracture healing compared to the control group. This was evidenced by increased callus formation observed through micro-CT imaging, improved histological features indicative of accelerated bone regeneration, and superior biomechanical strength as confirmed by biomechanical testing. The findings suggest that ethanolic extracts of C. longa and M. oleifera may serve as a natural therapeutic strategy to promote fracture healing and prevent osteoporotic conditions. The distinct chemical profiles identified through TLC and HPLC analyses support their potential efficacy. However, further research is necessary to elucidate the underlying mechanisms and optimize dosage regimens for clinical applications.

Extraction Methods for Determining Phycocyanin in Marine Water Cyanobacterium Oscillatoria acuminata

By: Priti Dhamal , Babita Rana

Page No : 110-115

Abstract
This study systematically investigates the efficiency of various extraction methods for isolating phycocyanin from the marine cyanobacterium Oscillatoria acuminata, sourced from the Mumbai region. The identification of Oscillatoria acuminata was confirmed through a combination of morphological and molecular analyses. The extraction techniques evaluated included freeze-thaw, serial extraction, maceration, organic acid-based extraction, and inorganic extraction, with subsequent purification using ammonium sulfate precipitation. Results demonstrated that the extraction method significantly affected the phycocyanin yield and purity. Among the methods tested, freeze-thaw, and maceration emerged as the most effective. Specifically, the freeze-thaw method achieved yields of 40 mg/g (2 cycles, purity ratio 0.5) and 43 mg/g (3 cycles, purity ratio 0.9). The maceration method yielded 38 mg/g of phycocyanin with a purity ratio 0.2. Conversely, organic acid extraction using acetic acid and inorganic acid extraction with HCl resulted in negligible yields, rendering the data from these methods inconsequential. These findings highlight the critical role of freeze-thaw and maceration extraction techniques in optimizing phycocyanin production from Oscillatoria acuminata for large-scale industrial applications.

Potential Bacillus Species Utilized for Phosphate Solubilization to Improve the Phosphorus Bioavailability in the Rhizosphere of Abelmoschus Esculentus (L.) (Ladies’ Finger) and Capsicum Annuum (Green Chilli) (L.)

By: U. Muthuvel , Harinathan Balasundaram , Rahul M. Sonavale , K. Suresh

Page No : 116-136

Abstract
Modern sustainable agriculture increasingly utilizes biopesticides and biofertilizers, particularly to address phosphorus (P) deficiency. Traditional phosphate fertilizers are limited by their soil mobility, prompting interest in microorganisms that can convert insoluble P into bioavailable forms. This has led to the development of phosphate-solubilizing bioinoculants.
In this study, rhizosphere soil samples from maize (Zea mays L.) were collected, and approximately 30 colonies were isolated on nutrient agar, and then screened on Pikovskaya’s agar for phosphate solubilization. Five isolates showed solubilization capabilities, with one strain, identified as Bacillus sp., demonstrating the best performance. Optimization experiments revealed optimal growth conditions at pH 7, 40ºC, with dextrose as the carbon source and ammonium molybdate as the nitrogen source. A pot experiment was conducted with Ladies’ finger and Green Chilli plants to evaluate the isolates’ performance under actual circumstances. Treated plants consistently showed higher fresh and dry weights than the control group, along with significant increases in biochemical indicators like carotenoid and chlorophyll levels throughout the growth period.

Page No : 137-147

Abstract
Ursolic acid is a triterpenoid with anti-inflammatory, antioxidative, antiviral and antineoplastic activities. The present study aims to identify and quantify Ursolic acid in Ocimum kilimandscharicum Guerke leaf using HPTLC. Ocimum kilimandscharicum Guerke, commonly known as ‘Kapoori Tulsi’ in Hindi and ‘Camphor Basil’ in English is a traditional medicinal plant belonging to family Lamiaceae. Preliminary Phytochemical analysis indicated presence of various phytoconstituents like flavonoids, alkaloids, glycosides, resins, saponins, steroids, triterpenoids, tannins etc. in the leaves of this plant. This study also establishes certain quality control parameters for Ocimum kilimandscharicum Guerke leaf with the help of HPTLC fingerprint profile of methanolic extract. The chromatographic profile of the extract showed a band corresponding to that of standard Ursolic acid. The Rf value as well as the colour of the band was compared with that of standard Ursolic acid which indicated the presence of Ursolic acid in Ocimum kilimandscharicum Guerke leaf. Ursolic acid was further quantified by using HPTLC and was found to be 158 μg Ursolic acid/g of powdered leaf sample. Thus, Ocimum kilimandscharicum Guerke leaves can be considered as an alternative natural source for Ursolic acid.

By: U. Muthuvel , K. Suresh , S. Selvakumar , B. Harinathan

Page No : 166-180

Abstract
Daucus carota is an important vegetable which is ranked third among the succulent vegetables in world production. Excessive amount of inorganic fertilizer results in soil acidification, increased greenhouse gas (GHG) emissions, and increased eutrophication of water bodies, can be mitigated by soil amendment using PSB bio-fertilizers, which resulted in improved plant growth and productivity. In this present study, the chosen potential PSB strains Micrococcus luteus, Paenibacillus polymyxa after characterization were selected for inoculation, and the field experiment was conducted using randomized complete block design with three replications, and the influence of these phosphate solubilizers on the growth, yield and metabolism parameters were evaluated after growth of carrot plants. Both PSB strains showed higher than 180 (phosphate solubilisation efficiency), and reduced pH from 8.0 to below 6.0 indicates high phosphate solubilising efficiency, increased organic acid production, when treated with plants Carrot Test (CT) - (11-15), they tend to enhance the vegetative growth, yield and qualitative parameters of carrot plants when compared to other treatments Carrot Test (CT) -(1-5), Carrot Test (CT) -(6-10). The application of Phosphate-Solubilizing Bacteria (PSB) bio-fertilizers Carrot Test (CT) -(11-15) in combination with calcium phosphate would aid uptake of phosphorus for better crop growth and yield and under a long run would aid to substantially sustainable soil fertility.

By: Kumar Shantanu , Sanavar Soham , P.L. Uniyal , Arunjit Mayanglambam , Meenakshi Sharma

Page No : 181-191

Abstract
Bryophytes exhibit notable efficacy in biomonitoring to assess the levels and discern the origins of heavy metal pollution. Their exceptional ability to accumulate substantial quantities of heavy metals surpasses that of other taxonomic groups. Periodic chemical analyses of moss specimens can prove highly advantageous in elucidating the temporal trends in pollution. The current research focuses on examining the accumulation of the heavy metal cadmium in both mosses and their respective supporting substrates across five distinct locations in India, namely Srinagar (Garhwal) (site 1), Bhawali (site 2), Chakrata (site 3), Shimla (site 4), and Munnar (site 5). Statistical analysis revealed that the concentration of heavy metals in plant samples and their supporting substrates at the Bhawali site was significantly higher than in the other four sites. The Cd concentration recorded in plant sample and their substratum was 42.606 and 297.506 μg/g, respectively in Entodon prorepens collected from Bhawali. The plant samples and substratum exhibited the lowest cadmium (Cd) concentrations in Trachypodopsis serrulata (0.0096 μg/g in the plant sample and 0.0196 μg/g in the substratum) and Timmiella anomala (0.0046 μg/g in the plant sample) from Chakrata, Pogonatum microstomum (0.0096 μg/g in the plant sample and 0.0216 μg/g in the substratum) and Campylopus latinervis (0.0096 μg/g in the plant sample and 0.0176 μg/g in the substratum) from Shimla, and Campylopus subfragilis (0.0096 μg/g in the plant sample and 0.0186 μg/g in the substratum) from Munnar. The present study suggests that Entodon prorepens can be regarded as a species with tolerance capabilities, demonstrating a notable capacity to accumulate the heavy metal cadmium in its gametophore.

Abstract:
The major scenario of varietal detection using machine learning, deep learning, feature extraction, and image recognition is gaining more value nowadays. The limitations of identifying of Paddy varieties by observing seed morphology is a challenging task. Our present study demonstrates the above said limitation by exploring artificial intelligence on Traditional Paddy land races recognition. This study deals with feature extraction (colour and morphological features) and the identification of ten types of traditional paddy varieties through deep learning methods. The sample image was collected through a high-resolution mobile device, segmented, and resized for image preprocessing study. Sample sizes are increased through image augmentation techniques. Extracted and presented the color and morphological features of paddy varieties. For transfer learning approach, the pre-trained model ResNet50 was employed to identify the paddy variety. By training the paddy images, we obtained the results of the model testing accuracy is 99.05 per cent, which is highly reliable. Finally, the loss percentage and the confusion matrix of Paddy varieties with our fitted model are discussed. The traditional paddy varieties have a longer duration of growth morphogenesis (up to 180 days). The image resolution deep learning artificial intelligence paved an accurate approach on paddy varietal or landraces genus and species level detection within a short period of time.

Adoption of Integrated Pest Management Practices of Rice Cultivation in Manipur Chinvarmoi and T. Radha

By: Chinvarmoi , T. Radha

Page No : 211-218

Abstract
Integrated Pest Management (IPM) stands as an efficient and environmentally conscious system for pest control, adopting an ecological perspective that integrates multiple effective techniques into a unified program aimed at managing pest populations to prevent economic losses and reduce environmental harm. The indiscriminate and excessive use of synthetic pesticides has adversely affected ecosystems, agricultural sustainability, and food safety. This study, conducted in January 2024 across eight villages in Imphal West and East, Manipur, involved a random selection of 400 rice growers. Data were collected through structured questionnaires and personal interviews, with the questionnaire pre-tested for validity and reliability among 20 farmers from two villages. The study measured farmers’ knowledge and adoption of IPM practices. Results revealed high levels of knowledge and adoption for cultural methods (100 per cent), moderate knowledge levels for mechanical (80 per cent) and chemical (70 per cent) methods, and corresponding adoption rates of 77 per cent and 75 per cent, respectively. However, biological practices exhibited the lowest knowledge (44.2 per cent) and adoption (25 per cent) levels. ANOVA analysis indicated statistically significant differences in knowledge across age groups for all four practice categories, cultural, mechanical, chemical, and biological-leading to the rejection of the null hypothesis (H₀) at a significance level of α = 0.05.

Plant Disease Diagnosis with Special Reference on Traditional and Molecular Methods—An Overview 

By: Chandrama Mukherjee , Debapriya Choudhury , Shinjan Dey , Sikha Dutta

Page No : 219-235

Abstract
Plant diseases are one of the leading causes of crop failures worldwide. The world has witnessed some of the worst accounts of mass starvations incurred by plant diseases, such as the Irish potato famine in the 19th century and the 1943 Bengal famine in India that was precipitated by rice crop failure. Plant diseases lower the product quality or shelf-life of crops, decreasing the nutritional value of vegetables and fruits and reducing crop yields, also making some crops unfit for sale in the market. Loss of crop yield from plant diseases will result in hunger and starvation, especially in less-developed countries where access to disease-control methods is limited and annual losses of 30 to 50 per cent are not quite uncommon for major food crops. The increase in human population will require additional 70 per cent of food by 2050 which demands for an increase in agricultural productivity. This can only be achieved by the effective management of plant diseases. Successful disease control requires thorough knowledge of the causal agent and the disease cycle, host-pathogen interactions in relation to environmental factors, and cost. Although various methods have been used to diagnose pathogens of plant diseases, this article focuses on the traditional and molecular methods of diagnosis. This review discusses the approaches that have been used to identify some of the plant diseases observed in the crops and some other plants.

Page No : 254-269

Abstract:
In the present study the sulfated polysaccharides were extracted from Halimeda opuntia and partially purified by using a Diethylaminoethyl cellulose (DEAE-C) column. These sulfated polysaccharides were subjected further to evaluate their biological efficacies. The antibacterial activity of polysaccharides showed a maximum inhibition zone against Salmonella typhi. Free radical scavenging activity of Halimeda opuntia sulfated polysaccharides was assessed by total antioxidant capacity, reducing power assay, hydrogen peroxide scavenging activity, DPPH and ABTS assay. All these assays exhibited that the antioxidant activity of sulfated polysaccharides was concentration oriented. The sulfated polysaccharides also showed rich sources of antidiabetic efficacy. Sulfated polysaccharides have been increasingly studied over the years in the pharmaceutical field, given their potential usefulness in applications such as the design of drug delivery systems. The biochemical characterization of sulfated polysaccharides was studied and confirmed by the Fourier Transform Infrared Spectroscopy (FTIR), High Performance Liquid Chromatography (HPLC) and Gas Chromatography–Mass Spectrometry (GC-MS) analysis.

By: Bhavna Singh , Hitesh Solanki

Page No : 270-278

Abstract:
India is a highly diverse country in contrast to plants. Due to different geographical areas various types of vegetation are seen in India. Every part of India has unique local food. In our ancient culture, many local plants are used as food which is the source of multiple vitamins and minerals. WEPs have more nutritional value than cultivated plants. WEPs are used as vegetables, fruits, and spices. Different parts of plants like stems, leaves, and flowers are mainly used in cooking for making delicious food, and local people directly consume fruits and seeds. People in urban and semi-urban areas suffer from insufficient or lack of nutrients in their daily diet, and therefore many health-related issues seen in peoples. Local people are used WEPs for proper nutrition and minerals. They consume different plants according to the season and local availability of those plants. This review describes the method of consumption and their nutritional value. Among the different parts of the plant, fruit is the most consuming edible part of the plant. Cucurbitaceae and Rhamnaceae families contribute the highest number of plants as WEPs.

By: Arpita Banerjee , Renia Mullick , Suchita Sinha , Udisha Datta ,

Page No : 279-287

Abstract:
Relative study of three different Avicennia species has been done here for the annotation of Hypothetical Proteins (HPs). Avicennia alba (2), A. marina (13) and A. officinalis (4) HPs were chosen from the database NCBI for this study. The annotation has been done using several servers to know their functions and structures along with their probable locations and closest orthologous organism. Homology modelling (SWISS MODEL) has also been studied for knowing the probable 3D Model. The cellular locations including their role is estimated from CELLO. Anticipation of SignalP predicting signal peptides is studied. Nearly all of the protein sequences of Avicennia marina have orthologs belonging to Oryza varieties-Oryza glaberrima, Oryza rufipogon and also with Populus trichocarpa; whereas, A. alba has closest orthologs of its protein sequence to the protein sequence of Linum usitatissimum. A. officinalis failed to show any closest orthologs. The protein structure has been assessed by PHYRE2 and probable 3D Model along with Ramachandran Plot predicted by SWISS MODEL. The results generated showed that the protein sequences of Oryza varieties, Populus trichocarpa and Linum usitatissimum has similar stress and defense response genes like that of Avicennia. Hypothetical proteins have the capability for understanding a number of anonymous functions and structures of the given proteins, aiding in further analysis. Relative Evaluation is done in every single step to cross verify and to obtain the results

Identification and Development of EST-SSR Derived Functional Domain Marker (FDM) in Andrographis paniculata (Burm. F.) Nees: A Traditionally Important Medicinal Plant

By: Subhashis Das , Saurav Bhattacharya

Page No : 295-306

Abstract:
Andrographis paniculata (Burm. F.) Wall. ex Nees, also known as Kalmegh, is an important medicinal plant in the Acanthaceae family and has been widely utilised in Indian medicine for its therapeutic properties. EST-derived SSR markers have proven valuable in both diversification analysis and the creation of functional markers for assisted breeding due to their proximity to the protein-coding region. The current study involved the assembly of 708 EST sequences of A. paniculata, which represented various plant elements such as leaves, stems, and roots. This assembly process yielded 56 non-redundant perfect SSR sequences. The most abundant were the dinucleotide repeats (16; 28.57 %) followed by trinucleotide (15; 26.79 %), mononucleotide (13; 23.21 %), tetranucleotide (6; 10.71 %) and pentanucleotide (6; 10.71 %) SSR repeat sequence. The most abundant repeat was (AT)n followed by (AG)n in dinucleotide. Among the trinucleotide repeats, the most abundant repeat was (AAT)n followed by (ATC)n, whereas (AGC) n and (CCG)n showed equal frequency in distribution. Assembled SSR sequences were assigned to 150 unique functional domain markers using the InterproScan program, the most significant were Fructose bisphosphate aldolase class-I, chlorophyll A-B binding protein, cysteine-rich domain, 2Fe-2S ferredoxin binding, Helicase, C-terminal, cytoplasmic deadenylase NOT2/NOT3/NOT5, C-terminal and plant transcription factor. The functional annotation results of the selected SSR sequences, obtained using BLAST2GO, demonstrated their relationship with many significant molecular functions (MF), biological processes (BP), and cellular components (CC) in A. paniculata. Successfully, Insilco PCR amplification was performed using primer pairs that covered 12 SSR-EST contigs (21.4%) and 20 SSR-EST singletons (35.7%). The EST-SSR primers were validated using standard PCR amplification reaction with genomic DNA samples obtained from wild individuals of A. paniculata. The results demonstrated the successful amplification and presence of polymorphic bands, indicating the usefulness of the developed functional EST-SSR markers in A. paniculata. The current results reveal a novel set of SSR markers that are strongly linked to various functional domains. These markers can be utilized in future research on the genetic diversity across A.paniculata diversity analysis, as well as in marker-assisted breeding.

Abstract:
This study investigates the bioactive compounds in Kigelia pinnata (Jacq.) DC. leaves to evaluate their antioxidant and antibacterial potential. Fourier Transform Infrared Spectroscopy (FTIR) was used for analysing the functional groups found in the leaf extract, while qualitative phytochemical analysis and Gas Chromatography-Mass Spectrometry (GC-MS) were conducted to identify chemical components. Antioxidant potential was determined using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, and Escherichia coli was utilised for antibacterial assessment. Results of phytochemical analysis revealed the existence of tannins, carbohydrates, saponins, flavonoids, and phenolics. GC-MS analysis identified sydnone, 3-(4-carboxyphenyl), as the major bioactive compound. The extract exhibits antioxidant activity with an IC₅₀ value of 442.01 μg/mL. The leaf extract exhibited significant inhibition, with a maximum inhibition zone of 1.36 ± 0.05 cm observed at the highest concentration. In conclusion, these findings highlight K. pinnata leaf extract as a rich reservoir of bioactive compounds with potent medicinal and pharmaceutical applications.

Phytochemical and HPTLC Fingerprint Analysis for Triterpenes Identification from Simarouba glauca DC 

By: Ashida S. , Sushama Raj R V

Page No : 320-333

Abstract: 
With an emphasis on triterpene chemicals, the current study examined the phytochemical makeup of Simarouba glauca hexane extract column fractions isolated from leaves using High-Performance Thin Layer Chromatography (HPTLC). Phenols, flavonoids, terpenes, steroids, and glycosides were detected by qualitative analysis. Significant phytochemical content was revealed by quantitative analysis as: phenols (565.33±12.85 mgGAE/g), flavonoids (255.3±0 mg QE/g), and terpenes (75.7±1.82mg/mg) in the sample. The definitive detection of beta sitosterol in fractions F3, F4, and F5, with Rf values ranging from 0.161 to 0.167, is one of the major findings. Notably, betulinic acid was not present in any of the fractions that were examined, in contrast to what was initially anticipated. Using thorough confirmation techniques, the study compared fluorescence patterns, band hues, and Rf values to those of reference substances. The study emphasises how crucial it is to use several parameters when utilising HPTLC to analyse a specific molecule. The identification of the phytochemicals sheds light on the possible medical uses of Simarouba glauca DC leaf extracts.

Page No : 357-366

Abstract
Study of insect pollinator diversity and pollen carrying capacity was carried out in the mango orchards of the Northern part of Malda district, West Bengal, India. The diversity study of pollinators has revealed that Diptera, Hymenoptera are the most abundant groups, followed by others. Episyrphus spp, Eristalinus taeniops, Apis spp, Musca spp and Calliphora spp were the most abundant pollinator species found within the community of abundant insect pollinators in the study period. The calculated pollinator diversity indices have revealed moderate diversity as noticed by the values of the Simpson index (0.3013), Shannon index (2.308), or Margalef Index (1.637). Pollen carrying capacity was found to be comparably higher in the honey bee (Apis spp; 275±33.07) than the other pollinators due to its larger body size. A distinctive positive correlation (r = +0.80) was observed between body size and pollen load. Apis spp has a larger body size and greater pollen load, but it can’t be stated that it is the most efficient pollinator for lesser abundance (9.14). Episyrphus spp can be considered as the most efficient pollinator due to its enormous abundance (59.57) and higher visitation frequency, although it has a smaller body size with the lowest pollen load (100±19.09).

In silico and Pharmacokinetic Activity of Bioactive Compounds from Syzygium jambos (L.) Alston against Bcl-XL and COX-2: Potential Therapeutic Targets for Neuroblastoma

By: Jennifer Stanley , Shanthi Periyasamy

Page No : 367-379

Abstract
Cancer is a complex disease characterised by uncontrolled cell growth, evasion of apoptosis, and dysregulation of key signaling pathways, necessitating the search for novel therapeutic compounds from natural sources. Objectives: To identify potential inhibitors, present in Syzygium jambos (L.) Alston leaves targeting anti-apoptotic activity and cell cycle regulation, both of which are crucial in neuroblastoma progression. Methods: In this study, molecular authentication of Syzygium jambos leaves was performed through DNA isolation, PCR, and Sequencing. The ethanolic leaf extract was analyzed by UV-vis, FTIR, and GC-MS. Functional compounds from the GC-MS spectrum were docked with Bcl-XL (PDB: 1EVE) and COX2 (PDB: 1CX2) using Autodock Vina. Pharmacokinetic and pharmacodynamic attributes of the chemical compounds were studied by the Swiss ADME tool. Results: The PCR amplification of the rbcL gene yielded a ~600bp fragment and sequencing confirmed the identity of S. jambos (GenBank Accession No. PP754605.1), and phylogenetic analysis revealed a distinct clade closely related to other Syzygium species. Comprehensive analyses using UV spectroscopy, FTIR, and GC-MS identified 15 major bioactive compounds, including anthraquinones, cyclopropane, and silyl derivatives. Docking showed that N-Cinnamoyl-N-(4-methoxyphenyl)-aminomalonic acid, diethyl ester could serve as a potentially active inhibitor against the oncogenic targets Bcl-XL and cyclooxygenase-2, suggesting antiinflammatory potential, with binding affinities of −9.3 kcal/mol for Bcl-XL and −8.7 kcal/mol for 1CX2. Conclusion: These interactions indicate the potential of the compounds as Bcl-XL inhibitors to promote apoptosis and as COX-2 inhibitors for anti-inflammatory effects, highlighting the S. jambos ethanol extract as a promising source of bioactive compounds for neuroblastoma treatment.

Abstract
Present study is based on the Mehak cultivar of Coriandrum sativum L. grown in the Union Territory of Jammu and Kashmir. Plants were analysed for their floral phenological events, reproductive output and GCMS analysis of ethanolic extract of their leaves for the first time from Jammu. Sex expression is andromonoecy with staminate and perfect flowers are present in each umbellet of every umbel. Flowering is centripetal i.e. peripheral umbellets are the first to bloom followed by the central umbellets. Each flower shows protandrous condition which is responsible for the visitation of various insects to ensure the successful pollination. Percentage fruit set was found to be higher on open pollination in comparable to bagging depicting the role of the insects in pollination. With respect to GCMS, a total of 115 compounds have been reported from ethanolic extract of coriander leaves. Among these, Z, Z-4,15-Octadecadien- 1-ol acetate is present dominantly with peak area 15.74 per cent at retention time 38.04. Various other compounds have also been observed such as Pallensin, 1-Nonadecene, Phytyl stearate, 1-Hexacosanol, Stigmasterol, 9, 12, 15-Octadecatrienoic acid, 2, 3-dihyd, 13-Docosenamide, n-Hexadecanoic acid etc. Pallensin is a eudesmanolide which has been reported for the first time from the coriander leaves. All compounds are associated with various biological activities such as antioxidant, antibacterial, anticancer, anti-diabetic, anti-tumor, antimicrobial, hepatoprotective, anti-arthritic, anti-asthma and diuretic activity. On the basis of these activities, coriander can be recommended as a plant of pharmaceutical importance.

A Review: Bioprospecting Natural Fibers from Invasive Alien Plant Species (IAPs) for Application in Biocomposites

By: Mithu Biswas

Page No : 401-418

Abstract
Natural Fiber Composites or biocomposites have gained a lot of significance because of their uniqueness in properties compared to synthetic fiber composites. The use of natural fibers of commercial importance such as cotton, hemp, sisal, jute, flax, kenaf, etc. makes biocomposite a high-end product. Bioprospecting Invasive Alien Plant species (IAPs) as an alternative source of natural fiber, could reduce the pressure on native resources and curtail water, pesticide and fertilizer application rates. IAPs are potential sources of natural fiber with high crystallinity index, making them suitable for reinforcing composite materials. The use of plant fibers in composites requires critical analysis of physico-chemical properties of the fiber, such as cellulose, hemicellulose, lignin and wax content, fiber microstructure, aspect ratio, density, Microfibrillar Angle (MFA), Crystallinity Index (XRD Analysis), Thermal Stability (TGA Analysis), Surface Chemistry (FTIR Spectroscopy), Surface Morphology (SEM Analysis) and Mechanical Strength (Tensile strength and Modulus of elasticity). Non-wood plant fibers of Ageratina adenophora, Girardinia heterophylla, Mikania micrantha and Pennisetum purpureum have high crystallinity index (68.98 per cent to 79.1 per cent). Ageratina adenophora, Cryptostegia grandiflora, Eichhornia crassipes and Girardinia heterophylla have high cellulose (> 65 per cent) with low lignin content (<12.5%), which minimises the concentration and duration of chemical pretreatment. This review paper analyses the physico-chemical properties of natural fibers of 20 IAPs and the feasibility of their application in biocomposite using different polymer matrices.

In Vivo Evaluation of Two Medicinal Fern Extracts for Management of Leaf Spot Disease in Centella asiatica (L.) Urb.

By: D. Herin Sheeba Gracelin , S. Suga , M. Muthu Sheeba , C. Baby Shalini

Page No : 426-437

Abstract
Bacterial leaf spot disease caused by Xanthomonas campestris pv. centellae (Xcpvc) is a major constraint in the cultivation of Centella asiatica (L.) Urban. C. asiatica, a perennial herb belonging to the family Umbelliferae, is widely valued for its medicinal properties, including antihypertensive, antiallergic, anticancer, wound-healing, and bronchodilatory effects. However, the occurrence of leaf spot disease severely diminishes the quality of the leaves, thereby reducing market value and farmers’ income. Pteridophytes, one of the oldest groups of vascular cryptogams, possess notable medicinal potential, and many species have been traditionally used for therapeutic purposes. Based on their medicinal relevance, two ferns—Pteris biaurita L. and Angiopteris evecta (G. Forst.) Hoffm. were selected for the present investigation to assess their biocontrol potential against Xcpvc. The study involved determining the LD50 value of the pathogen, conducting in vivo pot experiments and field trials using the selected fern extracts, and analysing the histology of healthy and infected leaves to evaluate anatomical responses to bacterial infection. Among the two ferns tested, Pteris biaurita L. demonstrated significant efficacy in disease suppression, as evidenced by reduced symptom severity and favorable histopathological responses. These findings suggest that fern-based biocontrol strategies, particularly using P.biaurita, could serve as an eco-friendly and effective approach to manage bacterial leaf spot disease in C. asiatica.

By: Archana. P.J. , Pinkie Cherian

Page No : 438-445

Abstract
Diabetes mellitus, marked by high blood glucose, is a global health concern requiring alternative management strategies. This study explores the potential of Vernonia travancorica Hook. f., an endemic tree from the Southern Western Ghats of India, as a natural remedy. Although used in indigenous medicine, its antidiabetic properties remain underexplored. Through phytochemical analysis, the study aims to identify bioactive compounds with therapeutic effects on glucose regulation. The research compares the inhibitory potential of acarbose, a diabetes drug, with ethanolic extracts from different plant parts of V. travancorica. Acarbose showed the highest efficacy (IC50 = 291.02 μg/mL). Among plant extracts, the leaf extract exhibited the second-highest efficacy in inhibiting alpha-amylase (IC50 = 608.645 μg/mL), followed by floral and stem extracts. For alpha-glucosidase inhibition, the leaf extract was most effective (IC50 = 587.115 μg/mL). The study suggests further investigation into these extracts’ potential for diabetes management.

Studies on Seasonal Variabilities of Marine Diatom Communities, Bakkhali Coastal Sites, Bay of Bengal, India

By: Roni Saha , Subhas Giri , Amal Kumar Mondal

Page No : 446-454

Abstract
The present study describes the community structure and drivers of diatoms in the Bay of Bengal. Data were collected on phytoplankton and a range of environmental and hydrological variables from India’s estuarine and creek habitats during a calendar year from pre-monsoon to post-monsoon. This is the first study on diatom diversity in Bakkhali. A total of 19 diatoms genera are found in sampling sites. Different abiotic factors are the main drivers that change their number in different sessions of a calendar year. Micronutrient concentration is responsible (silicate, nitrate, and ortho-phosphate) as the most important driver of phytoplankton in all habitats. The Nitrate concentration ranges from 51.23 to 71.20 μM, while Ortho-phosphate concentrations varied from 4.09 to 6.39 μM, dissolved silicate ranges from 44.07 to 21.7 μM in both sampling stations. The hydrological parameters are also a driver that changes the diatom community. These findings suggest that phytoplankton play a crucial role in regulating phytoplankton community composition.

Key Determinants of High Frequency Shoot Regeneration in Sesamum Indicum Cotyledons

By: Poudhi Samadder , Neelakantan Arumugam

Page No : 460-471

Abstract
Despite being the oldest edible oilseed crop, sesame has not reached its potential in biotechnology due to its recalcitrant nature in in vitro conditions, and a reliable shoot regeneration protocol remains elusive. In this study, a high frequency shoot regeneration system applicable to at least 45 different varieties of Sesamum indicum is presented. Combinatorial effect of 6-Benzylaminopurine (BAP) and Indole-3- acetic acid (IAA), ideal sucrose concentration and media of choice were explored, demonstrating that N6 medium augmented with 5 mg/l BAP, 1 mg/l IAA, and 5 mg/l AgNO3, as well as an initial culture on 6 per cent sucrose for two weeks followed by 3 per cent sucrose, significantly improves shoot regeneration. In this medium 73 per cent of the genotypes exhibited shoot regeneration ranging from 31 per cent to 72 per cent, marking the first report of such broad testing in sesame.

Page No : 472-487

Abstract
Parthenium hysterophorus L. is traditionally used by local tribes to treat skin infections; however, scientific validation of its medicinal properties remains limited. The present study aimed to investigate the phytochemical composition and identify potential bioactive compounds of P. hysterophorus L. using Gas Chromatography–Mass Spectrometry (GC-MS) and evaluate the antibacterial activities of its crude extracts against plant pathogens. Crude extracts were prepared using the maceration method with water as the solvent. Preliminary phytochemical screening revealed the presence of key secondary metabolites, including phenols, flavonoids, tannins, alkaloids, and terpenoids. Quantitative analysis showed that the leaf extract contained the highest total phenolic content (9.33 ± 0.01 mg GAE/g), followed by the flower extract (6.86 ± 0.01 mg GAE/g). The leaf extract also exhibited the highest levels of flavonoids (1789.62 ± 6.70 mg QE/g) and alkaloids (1465.72 ± 1.81 mg AE/g). In contrast, the flower extract recorded the highest tannin content (11.21 ± 1.72 mg TAE/g). Antioxidant activity was assessed using DPPH, FRAP, and ABTS assays. The leaf extract demonstrated the highest antioxidant potential with 10.73 per cent DPPH scavenging, 256.92 AAE/g in FRAP, and 22.71 per cent ABTS inhibition. Antibacterial activity against Ralstonia solanacearum and Erwinia carotovora was evaluated using the agar well diffusion. At a 90 mg/mL concentration, the leaf extract exhibited antibacterial efficacy comparable to ciprofloxacin (0.5 mcg), particularly against R. solanacearum, indicating a more substantial inhibitory effect than on E. carotovora. GC-MS analysis of the leaf extract identified several bioactive compounds, including 2-Pentanone, 4-hydroxy-4-methyl-, Benzene, 2,4-dichloro-1-methyl, 1-Dodecanol, 2,4-Ditert- butylphenol, Heneicosane, Eicosane, and Neophytadiene. These compounds are known for their antibacterial, anti-inflammatory, insecticidal, antioxidant, cytotoxic, and pesticidal properties. Overall, these findings offer a novel and fundamental basis for the purification and development of plant-derived bioactive compounds with potential applications in pharmaceuticals.

Page No : 26-31

Abstract
Anisochilus Wall. ex Benth is a genus of Lamiaceae family which includes medicinally and ethnobotani- cally important species like A. carnosus. It is a taxonomically significant genus because of its close similarity in morphological characters. There exists difficulty in identification of the species due to similar morphology. The present study attempts to molecularly validate two species of the genus, A. scaber and A. kanyakumariensis. from the Western Ghats of India using chloroplast (rbcL) and nuclear (ITS2) regions. In both species, rbcL works efficiently, however the ITS2 primer yielded no results. Gene sequences were submitted in NCBI. Evolutionary relationship of subtribe plectranthinae using Neighbour-Joining method is also discussed here.

In vitro Cytotoxicity and Phytochemical Screening of Extracts from Selected Medicinal Plants Against Distinct Human Cancer Cell Lines

By: Anil Kumar H. S. , Kotresha D.

Page No : 32-41

Abstract
In this current study, in pursuit of novel anti-cancer alternative medicines, four medicinal plant extracts were investigated for phytochemical screening and in vitro cytotoxicity studies, and the most potent cytotoxic extract was utilised for qualitative analysis. For preliminary phytochemical screening, three phytochemical extracts, namely ethyl acetate extract (EAE), methanol extract (ME), and distilled water extract (DWE), of four plants, namely Antigonon leptopus Hook. & Arn., Aristolochia bracteolata Lam., Dodonaea viscosa Jacq., and Thespesia populnea (L.) Sol. ex Corr., were screened, and the same were screened for in vitro cytotoxicity by MTT assay against four cell lines: namely Human Colorectal adenocarcinoma (HCT 116), Human Hepatocellular adenocarcinoma (HepG2), Human lung carcinoma (NCIH-460), and Human Prostate adenocarcinoma (PC3). The presence of several phytochemicals was identified during the phytochemical screening. All IC50 values mentioning 17.50 and 29.47 μg/ml of EAE of A. bracteolata were found to have the strongest anticancer activity against NCIH-460 and HCT-116 cell lines, respectively. The EAE at IC50 of 17.50 μg/ml accounts for about 30 compounds after a qualitative GC-MS study, and it includes anticancer chemicals such as pentadeconic acid, phytol, phenol-2,4-bis 1,1-dimethylethyl, 2,6,10-trimethyl-14-ethylene-14-pentadecene, phytol-acetate, and others. The extract of ethyl acetate from A. bracteolata strongly suppressed the growth of malignant cell lines NCIH-460 and HCT-116 and included many physiologically active chemicals. This could be the first evidence of the antitumor efficacy of A. bracteolata in lung and colorectal cancer screening.

Functional Characterization of OsbHLH185 Transcription Factor in Arabidopsis Under Abiotic Stresses

By: Roshan K. V. Remesh , Jyothish Madambikattil Sasi , Biju Dharmapalan , Dhanya D.S

Page No : 42-49

Abstract
Basic helix-loop-helix (bHLH) transcription factors play a pivotal role in governing various cellular processes associated with growth, development, and stress responses in plants. The current investigation aimed to conduct a functional characterization of a rice bHLH transcription factor gene, OsbHLH185, under several abiotic stress conditions, namely salt stress, mannitol stress, cold stress, and the application of abscisic acid (ABA). Transgenic Arabidopsis lines of OsbHLH185 were produced by over expression techniques and afterward employed for the investigation of stress response. The phenotypic, morphometric, and physiological parameters of the over-expression lines were assessed in the context of abiotic stressors. The transgenic plants with over-expression lines demonstrated a notable increase in tolerance to abiotic stress in comparison to the non-transgenic wild-type plants. The OsbHLH185 over expression lines had increased levels of the ABA biosynthesis gene NCED3 and signaling genes, which may be the cause of the phenotype of abiotic stress tolerance. The findings of this initial study can serve as a valuable resource for future investigations, while the utilization of OsbHLH185 in breeding research holds potential for the enhancement of abiotic stress tolerance in crop species.

Effect of Chromium Oxide on the Growth Efficiency of Phormidium autumnale (Agardh)

By: S. Bagampriyal , B. Sadhana

Page No : 62-69

Abstract
Cyanobacteria are a diverse group of photosynthetic procaryotic organisms grow well in different environments. They have an ability to fix atmospheric nitrogen. It can grow in heavy metal polluted environment by adsorbing the metal ions from the surrounding aquatic system. The present study analyzed the effect of chromium oxide concentrations on the growth of Phormidium autumnale by estimating the photosynthetic efficiency and physiological tolerance of organisms. Phormidium autumnale was isolated from the paddy field soil of Sakkimangalam, Madurai district, Tamil Nadu by using Blue green algal medium. It was treated with various concentrations of chromium oxide from 0.1ppm to 1ppm and estimating the photosynthetic pigments: chlorophyll a, phycocyanin, phycoerythrin, allophycocyanins and total nitrogen, protein and ammonia excretion in the culture medium. This study reported that the various concentrations of such chromium ions enhanced the photosynthetic and physiological efficiency of Phormidium autumnale and was well grown at the low concentrations of chromium ions. It was confirmed by estimating its photosynthetic efficiency, nitrogen fixation, protein content and ammonia excretion by the algal cells at various concentrations of chromium oxide. Its higher concentration affected the Phormidium growth when compared to control. This organism showed metal tolerance against the lower concentrations of Chromium oxide. Thus, this work has suggested that the application of cyanobacteria: Phormidium species distribution in the paddy field soil pretentiously fixed atmospheric nitrogen and showed the tolerance effect against the various applications of agro-chemicals with heavy metals generally applied in crop fields. The novelty of the work stated that the Cyanobacteria Phormidium showed metal tolerance against the chromium oxide at lower concentrations in aquatic medium.

By: Johnnita Tirkey , Nihar Ranjan Nayak

Page No : 70-78

Abstract
Dendrobium hybrid orchids are widely used for potted flowers as well as for cut flowers. In this study, the Dendrobium hybrid (D. Apichart Rainbow x D. bigibbum var. compactum) widely used as the potted f lower because of the unique flower qualities was used. Availability of the planting materials is the major constraint for which the use of tissue culture technology is highly essential. Seed pods were formed through hand pollination on the plants growing at the orchidarium and mature seeds were brought to the laboratory. After surface sterilization and culturing on Murashige and Skoog’s (1962) medium for germination and further seedling development. Effects of different plant growth regulators on the seed germination were thoroughly analysed, and it was found that the seeds on BAP 0.25 mg/l showed the highest rates (90. 52%) of germination at 90 days of culture. On the same medium, at 18 months of culture healthy seedlings were formed, each had 2.0 roots and 3.0 leaves. The seedlings reached a height of 4cm at 18 months of culture. The young shoots produced on BAP 0.5 mg/l were used as the explants for the production of new shoots. The inclusion of BAP 2.5 mg/l showed the highest production of 15.0 shoots from each explant. The new shoots were transferred to MS nutrient medium containing 2.0 mg/l IBA for efficient root induction in which each shoot produced 4.33 numbers of roots at 180 days of culture. In vitro, raised shoots were successfully acclimated in the greenhouse for further growth and development.

Biochemical Changes and Oxidative Stress Responses in Allium cepa L. affected by Iron Oxide Nanoparticles

By: Rameena K Jamal , Vimala Jose

Page No : 103-111

Abstract
The use of nanotechnology in agriculture has a positive influence on the food industry along with opening a new area of research in agroecosystems. In this paper, Iron (III) Oxide (Fe2 O3 ) nanoparticles (FeO NPs) were treated with onion (Allium cepa L.) seeds at various concentrations (1mM to 100mM) to investigate the effects on biochemical parameters, photosynthetic traits, and oxidative stress responses of seedlings. FeO-NPs were characterized using UV-Vis Spectroscopy (UV-Vis) and Scanning Electron Microscopy (SEM). Positive effects were observed in seed germination and the growth of seedlings at lower NPs concentrations. The germination percentage, photosynthetic pigments, and nutritional contents of seedlings were enhanced by 5 mM to 10 mM NPs treatments, also significant decrease in the parameters was not observed at higher concentrations. Antioxidant enzyme studies which could throw light on the toxicity of NPs indicated that FeO-NPs at high levels resulted in lower stress rates whereas the low to moderate concentrations of FeO-NPs were beneficial to the plants. In general, the results indicated that FeO-NPs at low concentrations (5mM) could be useful for onion germination, growth, and biomass production. An increase in the content of antioxidant enzymes at higher concentrations of FeO-NPs pointed towards the plant defence mechanisms against oxidative stress induced by FeO NPs at high (50mM) concentrations. The study gives the effects of Iron oxide nanoparticles on growth, photosynthetic traits, and biochemical parameters of onion seedlings.

Page No : 119-128

Abstract
Andrographis serpyllifolia is a traditional medicinal plant used in curing wounds and jaundice for its potential antimicrobial properties. The present study was aimed to screening of phytochemical constit uents of A. serpyllifolia and to investigate its antioxidant and antibacterial property. The results showed alkaloids, flavonoids, phenols, coumarins, polysterols, terpenoids, etc. Intriguingly, higher amounts of phenolic content and alkaloids were found in the stem, flavonoids in the root and stem and tannins in the leaf. The antioxidant potential of the plant extracts determined by different methods showed differential inhibition values and was concentration dependent. The higher DPPH and ABTS scavenging activity were found in stem and leaf extract with an IC50 value of 23.81±5.71 µg/mL and 3.70±1.38 µg/mL respec tively. The reducing power scavenging activity was higher in the leaf extract (136.17±24.24µg/mL) and stem (152.7±10.13µg/mL). Whereas the total antioxidant capacity was noticed in stem and root extracts. The antibacterial activity was done against both gram-positive and gram-negative bacterial strains. Comparatively, leaf and stem extracts were more effective against B. subtilis with a maximum zone of inhibition (19.66±1.23 and 19.29±1.40 mm) followed by root extracts against E. faecalis (22.19±1.86 mm) at 30 µg/µL. Further, the leaf, stem, and root extract were efficient against E. coli with the zone of inhibition of 23.46±2.51, 19.66±2.25 and 21.66±2.15 mm respectively, at 30 µg/µL concentration. The studies conclude that A. serpyllifolia is a rich source of potential phytochemicals with antioxidant and antibacterial properties.

Role of Endophytes in Modulating Pythium Infection in Zingiberaceae – A General Review

By: Divya L. , Mani Shankar Babu

Page No : 129-137

Abstract
The Zingiberaceae family is widely recognized for its therapeutic and medicinal properties. Most of the members of this family being valuable spice crop, significantly boost the local economy in the areas where they are grown. Ornamental value of some members reserves a unique position. Tropical and subtropical nations rely heavily on the commercial cultivation of ginger and turmeric. India is home to some of the most varied and abundant populations of Zingiberaceae. Rhizome rot is the most devastating disease caused by Pythium species evidenced with almost 90% crop loss. Current approaches of disease control cannot be fully relied upon. So, there is an urgent need for effective alternatives. Endophytes are being extensively investigated as a potent biotic agent to manage a variety of diseases in many crop plants. The purpose of this review is to enumerate the studies conducted on the feasibility of using endo phytes against Pythium infection in Zingiberaceae.

By: Manmohan Arya , Indu Singh Sankhla

Page No : 138-143

Abstract
In India the waste generated from agriculture crops does not have any proper industrial use. Mushroom is a fleshy, macroscopic fungus belonging to the basidiomycetes group of Mycota kingdom. Edible mushrooms have significant diversity in their cultivation. The climate of the northern hilly region of India is suitable for Agaricus whereas the southern is fit for Volvoriella cultivation. The subtropical region offers the perfect conditions for Pleurotus cultivation. Pleurotus has many species like P. ostreatus, P. florida, P. sapidus, P. djmor, P. eous etc. Pleurotus ostreatus is suitable for tropical and subtropical region of the country. Rajasthan produces several subtropical crops like Bajra, Mustard, and Wheat, which resulting in generation of lignocellulose-rich waste. This study investigated the impact of various agro-wastes on the growth of Pleurotus ostreatus. Three combinations of agro-crop wastes were employed and examined. Pleurotus ostreatus took the least amount of time for the spawn run in the Wheat-Mustard-Bajra (T3 ) combination, while the Wheat-Bajra (T1 ) combination saw the earliest primordia initiation. The T1 combination also saw the shortest maturation time and shortest harvesting period. Furthermore, among the three highest-weight individuals from each treatment, T3 exhibited larger dimensions compared to others, with weights of 22 gm, stem length of 6 cm, and cap dimensions of 8x9cm². Maximum harvested mushroom production (636 gm), biological efficiency (84.7%) and Moisture content (91.44%) were noted in the T2 combination. The goals of sustainable development will be met and an appropriate agro-waste for mushroom cultivation will be established with the aid of this study.

By: Lavanya Nallasamy , Amutha Swaminathan , Deepika Krishnamoorthy , Girija Sangari Murugavelu , Swarna Lakshmi Selvaraj

Page No : 163-189

Abstract
Rauvolfia tetraphylla L. is a medicinal plant renowned for its pharmacological properties, faces threats due to habitat destruction and over-exploitation. This study targeted to explore micropropagation techniques to mitigate these challenges and investigated seed germination, callus formation from various explants, direct organogenesis, and somatic embryogenesis. Surface sterilization methods were optimized to enhance seed germination rates. The seed coat is hard it prevents the seed germination, to overcomethe seed dormancy and the seeds were treated with 4℃ for 48 hours. The germination of 83.33% was achieved after the partial seed coat removal. Callus formation was induced from leaf, node, internode, and root explants using different hormone combinations. Maximum callus formation was observed on MS medium amended with 2,4-dichlorophenoxyacetic acid and 6 – benzyl amino- purine (2,4-D+BAP) in all explants. Hormone combinations also influenced direct root and shoot formation, with higher concentrations promoting greater responses. Somatic embryogenesis was induced in leaf and root explants using 2,4-D and BAP. Optimal concentrations (1.5 mg/L each) resulted in the formation of globular stage embryos. Histological analysis revealed distinct cellular processes during somatic embryogenesis, including embryo differentiation. It emphasizes the importance of hormone optimization and provides insights into the stomatic embryogenesis driving the plant regeneration in R. tetraphylla, offering valuable contributions to tissue culture protocols and conservation efforts for the endangered medicinal plant.

Evaluation of Cytotoxic Activities of Methanolic Extracts of Calotropis procera (Aiton) W.T. Aiton

By: Prantik Hazra , Arghya Ghosh

Page No : 190-196

Abstract
The present study aimed to investigate, the Brine shrimp activities and the larvicidal activities of Methanolic leaves and flower extracts of Calotropis procera. The larvicidal activities were studied on Anopheles, Culex, and Chironomus. Surviving larvae and brine shrimps were counted after every 3 hours up to 24 hours and the percentage of death at each dose and control was determined. The LC50 value of Brine Shrimps was 125 mg/ml at 24 hrs, for Anopheles larvae the value of this sample was 50 μg/ml at 24 hrs, for Culex larvae,75 μg/ml at 21 hrs, and for Chironomus larvae, 125 μg/ml at 18 hrs. Death of larvae was increased with the increased concentration of crude extract. However, the outcome of the study failed to show acute toxic effects on brine shrimp and Chironomus larvae; but significant toxicity was observed in methanolic leaf extracts of Calotropis procera in mosquito larvae. This could have serious implications in vector control strategies and minimizing impact on the environment.

Cycadofilicales (Pteridospermales)

By: Teena Agrawal , Prerana Badoni , Suman Kacholia , Manisha Chauhan

Page No : 197-205

Abstract
The discovery of this group of gymnosperms from the Palaeozoic era is one of the notable achievements of the palaeobotanist and it was of immense value to the palaeobotany & in phylogeny. It includes fern like plants which were dominant in the Devonian period. They extend into the beginning of the Mesozoic era, later on, there was a mass extinction of the pteridospermales, due to the misconception, that they were initially considered ferns and fern-like plants. Williamson (1897) first considered these plants as an intermediate of the ferns and cycads due to the morphological and anatomical similarity of the organs. H. Potonie (1899) was the first to give their names as the Cycadofilicales. Oliver and Scott ( 1904) named this group as pteridospermales due to the similarity between the ferns and spermatophytes. In this review article features of the order pteridospermales and their phylogeny have been discussed.

Evaluation of Anti-Microbial Properties and Phyto-Chemical Constituents of Methanolic Extracts of Leaf and Callus of Psoralea Corylifolia. L.

By: Gogikar Bhagirath , Md. Mustafa , G. Surendra Reddy , Y. Sravanthi

Page No : 207-215

Abstract
Psoralea corylifolia, locally known as Bakuchi, is a well-known medicinal plant noted for its myriad healthcare benefits. Every part of the plant encompasses several phyto-chemical constituents whose potential application is explored by many researchers in recent times. Though profound research is done on assessment of benefits of seeds and fruits of P. corylifolia, investigation of phyto-chemical constituents and beneficial properties of leaves remained an untouched area. Therefore, the present study focused on unveiling the bio-molecules in the leaves and callus grown using leaf explants in tissue culture. The optimum concentration for callus induction utilizing NAA and BAP hormones was determined to be 5.0 mg/L NAA combined with 0.5 mg/L BAP and 5.0 mg/L NAA combined with 0.5 mg/L KN with green friable callus. Using methanol as solvent, soxhlet extractor was used to extract phyto-chemical constituents from the dried callus powder. The phyto-chemical screening of the plant extract was carried out using standard protocols. Further, anti-microbial properties against bacteria and fungi were carried out. The presence of several phyto-chemical constituents like alkaloids, steroids, terpenoids, cardiac glycosides, anthraquinone glycosides, and flavonoids in both leaves and callu was observed in the present study. Both leaves and callus shown remarkable anti-bacterial properties, especially against Staphylococcus aureus, and MDR strains such as MRSA and VRE. In addition, significant anti-fungal activity was also witnessed against Candida albicans, Candida aureus, Cryptococcus neoformans, and Cryptococcus gattii by extracts of leaves and callus. As both leaves and callus having almost similar properties, micro-propagation using tissue culture can be exploited as a potential tool in preparation of healthcare products and this is especially useful in P. corylifolia because of its slow growing nature.

Page No : 216-226

Abstract
Sweet lime (Citrus limetta Risso), a citrus fruit from the Rutaceae family, is predominantly produced in Southeast Asia and contains high levels of water-soluble vitamins, minerals and antioxidants. Street vended sweet lime juice provides convenience for the consumer. However, quality and safety are major concerns. Therefore, the objective of the current study was to assess the microbial quality of sweet lime juice samples sold in Anand city, Gujarat, using the conventional culture technique as well as molecular characterization method focussing on Staphylococcus aureus, Bacillus cereus, Escherichia coli and Salmonella spp. Sweet lime juice samples were collected from seven popular locations of the city in duplicate (n = 14). For microbial screening, bacteria were isolated, biochemically characterized and their genomic DNA was amplified. Results suggested that majority of the samples were contaminated with microbes. Total viable count ranged from 6.39 to 7.52 log CFU/mL while yeast and mold count varied from 5.99 to 6.64 log CFU/mL. Out of the 14 samples tested, 02 (28.57%) isolates of B. cereus, 6 (85.71%) isolates of E. coli, and 3 (42.85%) isolates of Salmonella spp. tested positive using both the methods. For S. aureus, from the 07 isolates obtained by conventional culture technique, 05 were positive by the molecular method. The investigation reveals a significant health concern for consumers of street vended sweet lime juice samples. Consequently, there is a need to implement and enhance hygienic practices within the street food vending sector.

Transformation in Gossypium hirsutum cv. HS6: A Path to Efficient Phytohormonefree Protocol Overcoming Transformation Hurdle

By: Masnad Khan , Divya Sharma , Hussain Ara , Jawaid A. Khan

Page No : 227-234

Abstract
Cotton (Gossypium spp.) is a powerhouse of the textile industry, playing a crucial role in global fibre production. Unfortunately, cotton is not the easiest crop to genetically modify, it is highly recalcitrant with respect to transformation and regeneration. Despite progress in transformation protocols, it’s efficiency in many elite cotton varieties still remains around 0.01-3%. Certain cotton genotypes, such as coker, show more favourable responses to gene transfer, resulting in a dependence on these varieties for genetic alterations. A reliable and efficient protocol for transforming cotton was standardized in Gossypium hirsutum cv HS6. Shoot tip explants from in-vitro germinated cotton seedlings were cultured on MS medium. These explants were genetically transformed with Agrobacterium tumefaciens strain LBA4404, carrying pBI121 expression vector containing neomycin phosphotransferase (nptII) marker gene. The explants were consistently transferred every week to fresh MS selection media. Remarkably, unlike previous protocols that utilized various phytohormones for cotton regeneration, our procedure does not involve use of any phytohormones, yet the growth of shoots and roots was not affected by the absence of phytohormones. Interestingly, natural hormones within cotton plants regulate growth, eliminating the need for external phytohormones in the medium during tissue culture. The overall transformation efficiency reported in the current protocol was 5%, which is significantly higher than previous reports.

By: Rupjyoti Neog , Namrita Kola

Page No : 235-241

Abstract
Plant derivatives are gaining significant momentum in the field of medical science due to their broadspectrum therapeutic properties owing to drug resistance and harmful side effects associated with synthetic drugs. Staphylococcus aureus, is known for its multidrug-resistance against common antibiotics and is responsible for spreading various pathogenic diseases. The present in vitro investigation aimed to assess the antibacterial potential of methanolic extracts of Mikania micrantha, Corchorus capsularis and Centella asiatica plant against the gram-positive bacteria S. aureus (MTCC 7443) strain. Employing the agar well diffusion method, antibacterial activity at various concentrations of the plant extracts were evaluated. The results demonstrated a significant zone of inhibition (p≤0.05) for all the selected plant extracts. The plant extract from Mikania micrantha exhibited an inhibition zone of 14.7±0.71 mm and 19.33±0.58 mm; Corchorus capsularis showed 9.44±0.69 mm and 12.11±0.38 mm, while Centella asiatica showed 11.33±0.96 mm and 13.22±0.38 mm at 80 mg and 120 mg concentrations, respectively. The positive control demonstrated an inhibition zone of 11.23 mm whereas, the negative control showed no zone of inhibition. These findings suggest that the plant extracts possess a broad-spectrum antibacterial activity against the pathogenic bacterial strain, indicating their potential as a source of natural antibacterial compounds.

Abstract
Phytochemicals may serve as natural supplements in the field of pharmacology to control a variety of infectious diseases due to the diverse ways in which they affect on distinct types of disease. Identifying the particular solvent for the extraction of different phytoconstituents from a crude medication is significant. The crude extract of plant materials, have several benefits and there is a considerable chance of synergism between active components when a whole extract is employed, which can be lost when each of these components is isolated. The kind of medication being used and the solvent used can occasionally have an impact on the chemical makeup of the phytochemical components. Research indicates that these bioactive compounds have a range of beneficial effects on lowering the risk of diseases by reactive oxygen species. Holostemma ada-kodien is traditionally used for anti-diabetic effect, so the present study is to identify the best solvent and best plant part for the effect.

Seed Ecology and Seedling Phenology of Canscora alata (Roth) Wall.—A Threatened Medicinal Plant of the Family Gentianaceae

By: Bubai Bera , Arabinda Samanta , Prakash Karmakar

Page No : 254-263

Abstract
We studied the seed ecology and seedling phenology of Canscora alata. Seeds of C. alata are very small with very hard blackish-brown and reticulate testa. Mechanical scarification experiments explain that the seeds require strong to moderate scarification of hard testa to break dormancy for successful germination. The seeds remain viable only for one year after successfully dispersed into the soil. The final germination percentage (FGP) was only 11%, i.e., among the total seeds produced in a population, only 11% will germinate in the next year. Due to the low Germination Index (GI), the seed lots germinated slowly in the wild. Seedling shows phanerocotylar epigeal type of germination. After the emergence of the radicle, the seedling takes, on average, 48–58 days to complete its vegetative phase. The plant species C. alata is becoming more endangered in its natural habitat as a result of decreased seed viability and germination capabilities. Seedling ecology and phenological characteristics help protect threatened medicinal plants from anthropogenic disturbances in their wild ecological habitat. We expect that our study will contribute to further research and conservation planning for this threatened medicinal plant species.

The Phytochemical Profile of Medicinal Plants Cultivated Hydroponically: A Potential Tool to Revolutionise the Health Sector

By: Shital Chaukhande , Mangesh Dagawal

Page No : 270-288

Abstract
This paper aims to review the potential of hydroponics to improve phytochemical content of medicinal plants. The range of bioactive substances found in medicinal plants that support their therapeutic qualities is referred to as their phytochemical profile. There is a vast array of phytochemicals found in medicinal plants, depending on the type of plant and the hydroponic system employed; different hydroponic culture techniques will have different effects on the phytochemical profile of medicinal plants. Due to the regulated atmosphere and nutrient delivery in hydroponics, a medicinal plant grown in this method may have a different phytochemical profile than a plant grown in a standard soil-based system. When medicinal plant cultivated hydroponically, certain plants may display improved or changed phytochemical profiles, while others might not differ significantly from soil-based plants. Understanding the effects of hydroponics on a plant’s phytochemical content and therapeutic qualities typically requires research and experimenting with the particular plant of interest. The purpose of this review is to present an overview of the field’s existing cultivating technology and show how modern hydroponic techniques may be used to cultivate a finished product with a high concentration of specific metabolites, substantial nutritional value, and consistent and uniform quality. Although there is currently little research on this subject, it will undoubtedly grow in the future. As a result, this evaluation offers all the information required for similar future research.

By: Mayuresh J. Patil , Sangeeta A. Godbole

Page No : 317-325

Abstract
Trichosanthes bracteata, belonging to the family Cucurbitaceae is a rare wild plant and widely distributed in India. This plant has been reported to be used by tribals due to its excellent ethnobotanical medicinal uses. This paper presents the phytochemical content, qualitative and quantitative analysis of T. bracteata. Various parts of this plant were analyzed qualitatively to evaluate the presence of secondary metabolites in both polar and non-polar solvents. Phenolics, flavonoids, alkaloids and tannins, were the most abundant classes of compounds in methanolic extracts of both leaf and flower samples. Flavonoids were also detected in the leaf petroleum ether extracts. Terpenoids (Diterpenes and phytosterols) were strongly detected in stem (methanolic) as well as root and seed extracts of both solvents. Spectroscopic methods of estimation were further used to quantify the total phenolics, flavonoids, alkaloids and tannin content in methanolic extracts of various plant parts. Leaf extracts confirmed the presence of the highest amounts of flavonoids (8.14 mg/ gm), followed by alkaloids (1.164 mg/gm) and phenolics (1.109 mg/gm). The flower extracts confirmed the highest amounts of total phenolic compounds (9.079 mg/gm) and tannins (0.954 mg/gm).

Abstract
Whitefly (Bemisia tabaci) population poses significant threat to cotton production in tropical and subtropical countries, and act as a vector for plenty of viruses predominantly begomoviruses and associated satellite molecules. Plant mediated RNAi (PM-RNAi) based approach carrying in silico identified miR166b of Gossypium hirsutum cv. HS6 targeting ESTs (Expressed Sequence Tags) of B. tabaci has been effective against whitefly insect and also providing tolerance from cotton leaf curl disease (CLCuD) as reported earlier. Current study focuses on stability of transgene in subsequent generations of transgenic cotton lines and its effectiveness in providing protection against CLCuD. Subsequent generations showed reduced diseased symptoms and no phenotypic abnormality from exogenous construct. Overall findings demonstrate effectiveness of RNAi based construct against insect vector whitefly and its stable inheritance across subsequent generations underscore the potential of this approach for sustainable protection.

By: Bhumika Bharoliya , Farzin M. Parabia

Page No : 334-338

Abstract
Saffron (Crocus sativus L.) is a valuable geophyte plant and one of the most expensive spices in the world. In this study, two propagation techniques are used: plant tissue culture and hydroponics for vegetative propagation of Crocus sativus (Corms used) under controlled conditions. The study’s purpose is to compare and identify which propagation method will cover current and future demand with good yield, low cost and time. In plant tissue culture method, corm segments were cultured on MS media supplemented with various concentration of plant growth regulators. 60 tubes were inoculated and maintained at 20 °C with 16h light and 8h dark period. In hydroponics methods, saffron corm was inoculated in cocopeat and placed inside the plant tissue culture room at 19.5°C 16h light and 8h dark and at 47% room temperature. Using both techniques, the plant tissue culture approach revealed 15 (25%) tubes out of 60 showed germination and via the hydroponics method 11 corms (91.66%) showed single shoot germination with flowering (8.33%) after 7 weeks. It was concluded that hydroponic method is more practical for the saffron production in term of production, labor work, cost and time when compared to plant tissue culture technique.

Causes and Severity of Decline of Khejri (Prosopis cineraria) from Jhunjhunu District of Rajasthan, India

By: Manju Chaudhary

Page No : 339-345

Abstract
Prosopis cineraria (L.) Druce (Khejri) is a multipurpose tree that plays an important role in the rural economy of arid and semi-arid regions of Rajasthan. Recently the number of Khejri trees has continuously decreased and they are drying up. A comprehensive survey was conducted to investigate the causes and severity of P. cineraria tree mortality in the Jhunjhunu district of Rajasthan. Climate change, deepening of the water table, excessive lopping and use of modern machinery in farming damage the roots and make them vulnerable to pests and fungi. All the dry Khejri trees in the study area were infected by the root borer Acanthophorus serraticornis or the root rot Ganoderma lucidum or both. Inflorescence gall is another serious problem in Khejri trees as it significantly reduces pod formation. There is a dire need to make the local people aware of the causes of death of this multipurpose tree and motivate them to restore the Khejri cover in the area.

By: M.B. Manoj , M.H. Niranjan

Page No : 382-391

Abstract
Simarouba glauca DC. is a major plant in the Simaroubaceae family, with substantial biological activity and several therapeutic advantages in traditional medicine. This study aimed to assess the anticancer activity of different parts of S. glauca against Triple-negative Breast Cancer (TNBC) Cell lines (MDAMB-231). The cytotoxicity of methanolic extract of leaflet with rachis, bark and seeds of S. glauca was examined preliminarily using the MTT assays wherein it was observed that the leaflet with rachis extract offered maximum cytotoxicity with an IC50 of 1.55 mg mL-1. The plant extract-treated cells also displayed morphological changes, including cell shrinkage. Further, explored the impact of plant extract on cell cycle arrest and apoptosis induction, wherein it was discovered that the plant extract caused cell cycle arrest at G0 /G1 phase and affected early and late apoptosis significantly. The dual Acridine Orange (AO) and Ethidium Bromide (EB) fluorescence staining test demonstrated that the plant extract-treated MDA-MB-231 cells affected the cell shape, as seen by yellow to orange fluorescence. The comet assay revealed that cells appeared like comets upon treatment and showed a decrease in fluorescence intensity from head to tail, indicating damage to DNA. Based on our observations, it is evident that the leaflet with rachis possesses cytotoxic potential, thereby warranting the identification of the primary constituents for their application.

By: Sheikh Benazir , Rozina Yendrembam , Kananbala Sarangthem

Page No : 399-410

Abstract
Four local aromatic rice cultivars found in Manipur, India, namely Chakhao poireiton (R001), Chakhao angangba (R002), Chakhao angouba (R003) and Heitup phou (R004) were used to evaluate the responses in morphological, physiological and biochemical parameters under drought stress induced by polyethylene glycol-6000(PEG). The aromatic rice cultivars were subjected to drought stress treatment induced by four different concentrations of polyethylene glycol-6000 (0%, 10%, 15% and 20%). The results showed that the root and shoot lengths, fresh and dry weight of root and shoot, and total chlorophyll content, chlorophyll a, chlorophyll b Relative Water Content (RWC) were decreased under drought stress treatment. The activities of peroxidase (POD), catalase (CAT), superoxide dismutase (SOD), free amino acid content, proline, total soluble sugar and phenol content increased but the soluble protein content was found to be significantly decreased in R002 and R003 cultivars from 15% to 20% of PEG induced drought stress condition. Hence, from the present study it was observed that Heitup phou and Chakhao poireiton were comparatively tolerant and showed better performance in all the considered parameters as opposed to the control check cultivars (Sahbhagi dhan) while Chakhao angangba and Chakhao angougba were more sensitive to drought stress.

Assessment of Lead Bioaccumulation in Soybean at Different Growth Stages

By: Siddhi Gupta , Manoj Kumar Meena

Page No : 411-417

Abstract
In this research, Soybean (Glycine max (L.) Merr.) is treated with different concentration of lead ranging from 0 to 1000mg/kg of soil to understand how lead moves from soil different parts of the soybean plant, particularly during pre-flowering, peak-flowering, and post-flowering stages. It is crucial for assessing the risk of lead entering the food chain. Results indicated a direct correlation between soil lead concentration and plant lead accumulation, with the highest levels found at 1000 mg/kg. Specifically, at the post-flowering stage, lead concentrations were highest in roots (6.1443 mg/gm), followed by leaves (3.6115 mg/gm), shoots (2.6813 mg/gm), and seeds (0.4231 mg/gm). We analyzed Translocation Factors (TFs) and the bioconcentration factor for lead to understand the dynamics of lead translocation within the plant. TF and BCF value obtained were < 1. Our analysis revealed a distinct accumulation hierarchy, with roots accumulating the highest levels of lead, followed by leaves, stems, and seeds. Importantly, our study uncovered that lead levels in soybean seeds exceeded the permissible thresholds set by the World Health Organization (WHO) across all concentration levels. This highlights a significant potential risk associated with consuming soybean crops directly, emphasizing the need for urgent considerations regarding food safety.

In vitro Plant Development of Aerides Multiflora Roxb. and Genetic Fidelity Assessment through RAPD Marker

By: Purnima Paramanik , Subrata Raha , Dipak Kumar Kar

Page No : 418-425

Abstract
Aerides multiflora Roxb., also known as the Fox Tail Orchid, is a rare epiphytic orchid of the Purulia District of West Bengal with ornamental and therapeutic values. The plant’s wild populations have decreased due to limited natural regeneration and unrestricted commercial harvesting. Orchid seed germination relies on mycorrhizal symbiotic interaction. Our current research is focused on studying the germination of Aerides multiflora seeds and plantlet development using aseptic techniques to address the reduced natural regeneration process. This aseptic technique involves using Murashige and Skoog (MS) basal media with activated charcoal (AC) at different concentrations for seed germination, along with 6-Benzylaminopurine (BAP) and Naphthalene acetic acid (NAA) at varying concentrations for seedling development. The germination and protocorm formation varied widely, with the highest response (80.89 per cent) observed in the medium supplemented with 750 mg/l AC and the lowest (23.75 per cent) in the basal media. Most combinations tested showed variations in leaf and root formation and the percentages of multiple protocorm formation. Notably, MS medium with 750mg/l AC as the control, containing BAP 1.5 mg/l and NAA 0.5 mg/l, exhibited high percentages of leaf formation (90.5 per cent) and root formation (86.23 per cent). The plants were shifted to ex-vitro conditions and acclimatized with an 86.4 per cent survival rate. The in vitro grown plants were found to be identical clones of their parent plant with no signs of variation, as revealed by a Random Amplified Polymorphic DNA (RAPD) assessment. These findings will be helpful for the conservation and contribute to fulfil the demand of the floriculture and pharmaceutical industry through large-scale production.

Systematic Enumeration of Algal Taxa in Relation to Water Quality of Murguma dam, Purulia District, West Bengal

By: Pinaki Dey , Latika Sharan

Page No : 452-457

Abstract
Maintenance of freshwater resources and quality of their water is a big challenge inthe path of sustainable development. Based on the findings of more than five decades, it has been established that many algal taxa are regarded as bioindicators. They are pollution tolerant and an integral part of low-cost biological purification systems used for polluted water, especially those having organic pollutants. Keeping in view these attributes of algae, a study of Murguma reservoir and surrounding water bodies of Baghmundi block were carried out during 2020-2021 for algal taxa and physicochemical properties of water bodies. At present 17 parameters have been tested. These physicochemical and biological parameters have been studied from the surface water of selected five reservoirs for three years (2020-2022). One part of the Murguma reservoir shows oligotrophic water quality in physicochemical analysis and is also supported by the algal samples having genera like Cosmarium Corda, Spirogyra Link, Zygnema Agardh, and Oedogonium Link whereas algal samples collected from other sides are used by local communities for various day-to-day purposes including washing clothes, utensils, bathing, domesticated livestock washing etc. The algal flora of this zone of water included the members of Cyanophyceae, Chlorophyceae, and Bacillariophceae. Algal taxa such as Oscillatoria Voucher, Scenedesmus Meyen, Ankistrodesmus Corda, Phacus Dujardin, and Navicula Agardh, were recorded andare also included in Palmer’s genus pollution index. Organic pollution and eutrophication of water are obvious and reflected by algal flora. Awareness regarding the deterioration of water quality at rural and urban levels is always required. Widespread use and popularization of cheap Algal tools in water quality monitoring and phytoremediation can be of great help.

Micropropagation of Vetiver: A Sustainable Approach to Production of Essential Oil

By: Roshita Shrivastava , Ankan Singh , Shailja Verma , Rajneesh K. Agnihotri

Page No : 458-463

Abstract
In vitro plant regeneration of Vetiveria zizanioides (L.) Nash, which is synonymously known as Chrysopogon zizanioides (L.) Roberty was successfully achieved using a callus-mediated indirect organogenesis method. Rhizomatous explants were cultured on Murashige and Skoog’s (MS), 1962 medium, supplemented with various concentrations of 2, 4-D (2, 4-Dichlorophenoxyacetic acid) and kinetin. Optimal callus induction was observed in media containing 1 µM 2, 4-D and 0.25 µM kinetin. The induced callus was subsequently transferred to MS medium supplemented with 0.5 – 2.5 µM BAP (6-Benzylaminopurine) for shoot regeneration. Among the tested concentrations, 1.0 µM BAP was identified as the most effective for both shoot induction and multiplication. For rooting, the regenerated shoots were transferred to MS medium containing 0.5 µM NAA (Naphthaleneacetic acid), which facilitated robust root development. The acclimatization process involved transferring the plantlets to husk charcoal, where a high survival rate of 90 per cent was recorded. This study highlights an efficient protocol for the in vitro propagation of Vetiver, which can be crucial for its large-scale cultivation and conservation. The successful regeneration and high survival rate during acclimatization underscore the potential of this method for commercial applications and ecological restoration projects. The use of specific hormone concentrations for different stages of regeneration (callus induction, shoot regeneration, and rooting) provides a detailed framework for optimizing tissue culture conditions for Vetiveria zizanioides (L.) Nash. This research contributes to the broader understanding the role of plant tissue culture techniques and its practical applications in agriculture and environmental management for quality improvement.

Infrageneric Variability of Seed Coat Morphology in Some Members of Blyxa spp. Thou. (Hydrocharitaceae) from Eastern India and the Taxonomic Utility of Seed Characters

By: Debasis Bhunia

Page No : 464-481

Abstract
The present study examined micro-morphological characters of the seed coat of 4 endemic species of the genus Blyxa under a Light microscope and a scanning electron microscope from different aquatic zones of Eastern India. The characters are described and distinguished on basis of epidermal shape, exotesta, endotegmen, the sculpture of seed surface and endotegmen tuberculae. There were some differences between species in characteristics such as cell shape of seed coat, sculpture of seed surface and endotegmen tuberculae and these characteristics can serve as diagnostic ones for distinguishing species under the genus Blyxa in Hydrocharitaceae family. Seeds were very small in size in Blyxa japonica with 0.324 sq.mm (0.845 × 0.384mm) and large in B. aubertii with 0.908 sq.mm (1.220×0.745 mm). There were two types of seed coat surface distinguished, Type I: with three taxa, B. octandra, B. aubertii and B. echinosperma; showed seed coat sculpture with irregular longitudinal ridges or ribs; long spine and present apical-basal tails. Type II: with Blyxa japonica, the seed coat sculpture is reticulate with smooth surface.This micromorphology of the seed coat supports Hutchinson’s classification.

Goa Cowpea Cultivar 3 [Vigna unguiculata (L.) Walp]: Physico-chemical Characteristics, Nutritional Composition and Its Efficacy as Probiotic Carrier

By: Naik Varsha , Kerkar Savita , Rajendran Ananthan , KK Manohara

Page No : 482-494

Abstract
Goa Cowpea Cultivar 3 [Vigna unguiculata (L.) Walp] seeds of Leguminosae family, indigenously known as Alsando, is not explored for its nutritional, physicochemical properties and as a matrix for probiotic delivery. This study was undertaken to evaluate the selected nutritional components of Goa cowpea cultivar (GC3) and assess its efficacy in supporting the growth of probiotic bacteria. Seed nutritive value was comparable to that of ICMR, NIN values with protein, carbohydrate and total dietary fiber content being 26.88±1.28 g/100g, 59.41±1.22 g/100g and 21.7±1.28 g/100g respectively. The mean value of calcium and phosphorus concentrations were found to be higher (157.91±00.80 mg/100g and 277.26±00.35 mg/100g respectively). Total carotenoid content was 367.77±7.08 µg/100g. GC3 seeds displayed favorable physical and cooking properties, with doubling of seed size within 3h of soaking and 10 ± 0.0 min to pressure cook with lower gruel solid loss (7.45 ± 0.28 per cent) as compared to other cultivars reported. GC3 substrate effectively resulted in a six-log increase in probiotic cell count within 14 h-16 h fermentation with reduction in pH, viscosity and accumulation of organic acids with corresponding changes in total reducing sugars and amino nitrogen in the course of fermentation. Heat exposure of fermented GC3 revealed a probiotic count of ≥ 5 log cfu/mL up to 65°C. Lactobacillus fermentation inhibited the common gut and food pathogens and displayed susceptibility to some of the broad-spectrum antibiotics tested. This results on nutritional value of GC3, faster cooking and as a supportive growth matrix for probionts can be exploited by nutritionists and utilized for applications in food and health science.

Abstract
Cannonball tree (Couroupita guianensis Aubl.) a tropical plant belongs to Lecythidaceae family, and has a great potential source of bioactive compounds due its diverse ethnobotanical uses. The present study was carried out to assess the effect of different extraction solvents on the antioxidant properties and phytochemical profiles of various parts of C. guianensis. Among the different parts of C. guianensis evaluated, leaves exhibited the best antioxidant activity and highest amount of phytoconstituents in comparison to petals and bark. Moreover, methanol was identified as the most suitable solvent for extraction resulting in optimal IC50 values towards DPPH (212.54 μg/ml), ABTS (381.66 μg/ml) and metal chelation (442.64 μg/ml), as well as highest content of phenolic (82.92 mg GAE/g DW), flavonoids (12.06 mg QE/g DW) and total carotene. The methanolic extract of leaves showed promising inhibition potential against linoleic acid of 75.55% and phytochemicals like alkaloids, glycosides, tannins and terpenoids were found at elevated level. Therefore, methanol is recommended as optimal solvent for extracting bioactive compounds from C. guianensis leaves at significant level and may serve as potential antioxidant agent for further drug discovery and development.

By: Pramod V. Shelar , Ganesh D. Mankar , Om P. Sontakke , Uttam R. Wayase , Rajkumar B. Barmukh

Page No : 504-517

Abstract
The current investigation examines responses of different fenugreek varieties to salt stress during seed germination and early seedling stage to identify salt-tolerant varieties. Screening for salt tolerance can be achieved through a rapid, cost-effective, and reliable approach using seed germination and early seedling growth attributes. Fenugreek, a globally important crop, encounters challenges from salt stress, which notably diminishes its production by reducing growth and productivity. Salinity negatively impacted studied parameters, and deferential tolerance patterns were observed under different NaCl stress conditions. Multivariate analysis methods, such as Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), and Multiple Correlation Analysis (MCA), can be applied to identify saltresponsive attributes of tolerant varieties and to categorize varieties based on their salt tolerance levels. The findings of PCA analysis indicate that parameters like Final Germination Percentage (FGP), t Total Germination Index (TGI), Germination Index (GI), Shoot Length (SL), Root Length (RL), Fresh Weight (FW), and Seedling Vigour (SV) could serve as alternative or supplementary indicators for assessing salt tolerance at the varietal level. AFG1 was identified as the most salt-susceptible among the varieties studied, while RMT303 demonstrated the highest salt tolerance.These salt-tolerant and susceptible varieties can be explored for their biochemical, physiological, and molecular mechanisms underlying fenugreek’s salt tolerance, which could enhance breeding programs for improved resilience and benefit agriculture.

By: Sumita Nair , Neeraja Tutakne

Page No : 17-28

Abstract
Nanotechnology, an emerging scientific domain promises potential applications in varied sectors. Currently, research in nanotechnology focuses on the optimization of nanoparticle synthesis. Green synthesis of nanoparticles is an economic and non-toxic alternative to conventional methods. In the present study, aqueous bark extract of Ailanthus excelsa Roxb. was used for the biosynthesis of silver nanoparticles (AgNPs). UV-Visible Spectroscopy confirmed the presence of AgNPs with an absorption Surface Plasmon peak at 450nm. Biosynthesized AgNPs and bark extract were investigated using Fourier Transform Infrared Spectroscopy (FTIR) for determining the functional groups in phytochemicals that act as reducing and capping agents in the synthesis process. High-Resolution Transmission Electron Microscopy (HRTEM) analysis denotes that AgNPs were predominantly spherical, with an average size of 18.84 ± 2.28nm. The bark extract was evaluated qualitatively by preliminary phytochemical screening. Antioxidant potential of biosynthesized AgNPs and bark extract were analyzed using the DPPH method in which biosynthesized AgNPs showed significant free radical scavenging potential. Antibacterial properties of biosynthesized AgNPs were analysed against Escherichia coli and Staphylococcus aureus. Biosynthesized AgNPs and bark extract were also checked for Germination Percentage, Germination Speed Index and Seedling Vigor Index on Wheat (Triticum aestivum L.) and Moong (Vigna radiata (L.) R. Wilczek) seeds. The present study infers that Ailanthus excelsa Roxb. act as a potential source of green synthesis of AgNPs and may help to build a resilient system for its commercial applications in various fields.

Anthocyanins as Natural Plant-derived Antifungal Agents

By: Nirmalkar Vaishali , Ansari Shahana , Shaikh Asfiya , Momin Naziya

Page No : 29-38

Abstract
Anthocyanins are polyphenolic compounds found as natural pigments in various parts of plants that share the same diphenyl propane skeleton (C6 C3 C6 ) and are collectively known as flavonoids. They are water-soluble pigments responsible for the blue, purple, and red color of various plant parts and are particularly abundant in fruits, flowers, and vegetables. These pigments are natural colorants that are low to non-toxic. They also show antifungal, antibacterial, antioxidant, and food preservative properties. This study aims to perform in vitro analysis of the antifungal activity of anthocyanins extracted from different plant materials. Anthocyanins were extracted in acetone and acidified methanol. For qualitative determination of anthocyanins, thin layer chromatography was used whereas for quantitative determination pH differential method was used. The antifungal potential of anthocyanins was determined using the MIC and agar well diffusion methods against Penicillium sp. and Aspergillus sp. Acetone extract exhibited higher antifungal potential compared to acidified methanol extract against both fungal strains. It is suggested that anthocyanins, being strong antifungal agents, can be used to prevent fungal spoilage and deterioration of processed foods.

Sacred Groves: A Novice Idea for Carbon Sequestration

By: Alpesh Malsatar , PK Mehta

Page No : 57-66

Abstract
The daily anthropogenic advancements of humans have led to an increase in global carbon emissions. Every year, there has been an increase in the atmospheric concentration of carbon dioxide. One of the least expensive ways to minimize this gap is by biological carbon sequestration in plants. Ecosystems of forests are the most significant carbon sinks among terrestrial ecosystems and have long-term sustainable impacts on limiting climate change. Sacred groves are known as the small patches of conserved forests protected by man’s spiritual beliefs and cultural practices. These sacred forest patches were studied from the ecological, environmental and floristic point of view by several research workers. Due to their religious and mythological myths and beliefs, sacred groves and sacred plants are conserved well. Apart from being conserved, these sacred plants can also have a higher potential for carbon sequestration. The total biomass and carbon sequestrated in the Sacred tree species have been estimated using a non-destructive method. The main focus of the current article is on estimating the carbon sequestration of sacred tree species in sacred groves found in selected areas Abdasa Taluka of Kachchh District. Total 51 sacred groves were recorded from 33 villages which cover approximately 23.64 hectares of land area. Carbon sequestration of 537 individuals of 23 tree species was estimated through the standard method. Ficus benghalensis L. is dominated in carbon i.e., 7.36 tones followed by Tamarindus indica L. (5.77 tones), Ficus religiosa L. (5.22 tones), Delonix regia (Boj.) Raf (3.02 tonnes). Lowest carbon sequestration was recorded in Prosopsis cineraria (L.) Druce, Balanites aegyptiaca (L.) Delile, Azadirachta indica A. Juss., Butea monosperma (Lam.) Taub and Punica granetum L. less than 1 tonnes respectively.

Page No : 75-82

Abstract
The challenges in the management of diverse flora impacted by anthropogenic factors in areas governed by different land tenure systems are enormous notwithstanding lying in a classified biodiversity hot spot region in Meghalaya in North- east India. The attributes of the plant population in protected areas like Nongkhyllem Wildlife Sanctuary (NWLS), Nongkhyllem Forest (NRF), and District Council governed Eco-sensitive zone (ESZ) were studied using Important Value Index (IVI), Shannon’s and Weiner Diversity Index and Sorenson’s similarity index. Shorea robusta C.F.Gaertn., Tectona grandis Linn. L.f., Schima wallichii (D.C.) Korth, had the highest IVI value of 64, 56, 42, etc. respectively, while the diversity index showed maximum values of 0.78 in recorded forest area and minimum of 0.60 under district council area. Similarity index ranged between 16.67 % and 39.22 %. The species richness and diversity in the recorded forest area was higher compared to the forest under the district council. In addition, tree girth and density of other species were determined. The study revealed that the cultivation of betel nut (Areca catechu L.), betel leaf (Piper betle L.), broom (Thysanolaena maxima Kuntze) and banana (Musa spp.) though for livelihood and income generation contributed to vegetation alteration in the district council forest area. Strict enforcement of ESZ laws & creating alternative livelihood opportunities can help minimize biodiversity loss.

By: Aabid Hussain Mir , Rajib Borah , Nellie V. Kharbuli , Khrote-u Lasushe , Chaya Deori , Gunjana Chaudhury , Krishna Upadhaya , Hiranjit Choudhury

Page No : 163-175

Abstract
The present study was carried out to investigate the orchid diversity in community managed subtropical broad-leaved forests in Khasi Hills of Meghalaya. A total of 87 community forests were surveyed in Khasi Hills. The study revealed the presence of 123 species belonging to 54 genera. The highest numbers of species (66) were recorded in sacred forests, followed by reserved (51) and village (32) forests. Majority of the recorded species (87) were epiphytic and 36 were terrestrial. Of all the species, 28 (22.76%) were recorded as endemic and 12 (9.76%) were rare. Dendrobium with 19 species was the dominant genera followed by Coelogyne with 11 species. Owing to a number of anthropogenic disturbances followed by habitat loss, these species are subjected to continuous threat, hence warrants immediate conservation actions. Therefore, it is suggested that mass propagation, through conventional and tissue culture techniques should be adopted to conserve the dwindling orchid diversity of the state.

Page No : 239-248

Abstract
In the present investigation, urea coated hydroxyapatite nanoparticles (UHANPs) were synthesized, and characterized by using X-ray diffraction, FESEM, and FTIR techniques. Then, their effects at different concentrations (250 ppm, 500 ppm, 750 ppm, 1000 ppm) were observed for various enzymatic and non-enzymatic antioxidants of two varieties of Brassica juncea L. i.e. GIRIRAJ, and NRCBH101. Those were also weighup with control plants and plants grown in treatments with the same concentrations of urea. Results revealed that synthesized nanoparticles were 23-32 nm in size, and for all the parameters, the antioxidants like NPT, Polychelatins were found to the higher at treatment with 1000 ppm of Urea when compared to others while minimum concentration of these with UHANP (500 ppm). However, SOD increases with higher concentration of UHANPs and urea while other enzymatic antioxidants like APX and catalase declines. However, SOD declined with higher concentration of urea. All the results were statistically compared.

Citrus Fruit Peels: From Waste to Worth

By: Nidhi Parmar , V. H.Patel , Viraj Roghelia

Page No : 249-256

Abstract
Citrus fruits are most commonly consumed fruits. However, the peels of these fruits yield a huge waste. The peels also contain important phytoconstituents. This study aimed to investigate the antioxidant properties of peels of two selected citrus fruits (sweet lime and lemon). The peels were extracted using four solvents namely methanol, ethanol, acetone and distilled water. The extracts were analysed for total phenolic content, flavonoid content, DPPH radical scavenging activity and ferric ion reducing antioxidant power (FRAP). The result revealed that highest antioxidant profile was found for methanol extract of both sweet lime peel and lemon peel as compared to other extracts. The extracts of peels of sweet lime possessed higher total phenol, flavonoid and FRAP. The antioxidant capacity in terms of DPPH RSA and FRAP were attributed mainly to total phenolics as compared to flavonoids for both the peels. The higher antioxidant potential of peels of selected citrus fruits make them key ingredient for the development of functional foods and other supplementary products.

Invitro and Mass Multiplication of Cymbidium mastersii an Ornamental Orchid through Protocorm-like Body Formation

By: A. Kavitha , A. Rajani

Page No : 31-38

Abstract
The epiphytic orchid species known as Cymbidium mastersii can only be found in the region of India known as Northeast India. The preservation of wild populations faces a significant obstacle in the form of a significant threat when it comes to the necessity of obtaining an additional source of the material required to fulfil commercial demands. The objective of this research was to build an in vitro system for the bulk multiplication of C. mastersii, and it was successful in that endeavour. This required the capacity to control the growth of the seedlings through the development of the primary protocorm and germination from a limited number of fruit capsules. Also necessary was the ability to limit the amount of fruit capsules that could be used. Each protocorm resulted in the production of a number of robust plantlings that, once they had been separated from their mother plant, flourished in the conditions of the greenhouse. The child plants, in terms of both their size and the development they underwent, were genetically identical to their parent plant. The streamlined process will make it possible to cultivate Cymbidium mastersii for use in the commercial sector, which will reduce the negative influence on remaining viable wild populations. We offer here for the very first time a method of producing C. mastersii on a commercial scale that makes use of bioreactor technology.

Barium Promoted Seed Germination and Seedling Growth of Higher Plants in Solution Culture

By: Lokesh Kumar Choudhary , A. Kumar

Page No : 55-62

Abstract
The effects of various concentrations of barium (Ba) on seed germination and early seedling growth of wheat and mung bean were studied. Ba influenced the seedling growth of wheat and mung bean in similar fashion. Ba enhanced the germination relative index at lower concentration (upto 10 μg ml-1). The relative yield of biomass increased at lower doses of Ba and decreased at higher concentration (>100 μg ml-1). Lower applied doses of Ba showed a maximum index of tolerance while higher applied doses of metal showed a toxic effect on plant growth. The toxic effect of barium on mung bean was more marked than on wheat.

Unravelling the Mode of Action of Wound Healing Efficiency with the Compounds Screened from Hygrophila auriculata by Molecular Docking Studies

By: Deepika E , Santhy KS

Page No : 63-76

Abstract
Hygrophila auriculata is one of the traditional herbal plants utilized by many rural folks to heal wounds. According to the traditional knowledge, the roots of the plant would be highly effective for wound healing. The plant-based secondary metabolites remain an essential aspect in developing novel drug candidates. The early screening of bioactive compounds for a therapeutic property would be strongly evidenced to carry out the in vitro and in vivo studies. The current study focuses on screening bioactive compounds involved in wound healing using in silico molecular docking studies. The LCMS analysis of H. auriculata yielded about 15 compounds in positive and negative modes with the greatest medicinal properties. The drug-likeness, physicochemical properties, and bioactivity scores were evaluated for 15 compounds using SWISS ADME online tool. The compounds that indicate drug like properties and adhere to the permissible parameters are epiafzelechin, betulin, caffeic acid 3-glucoside, quercetin, palmitic acid, linoleic acid, chlorogenic acid, myristic acid, and 5, P coumaroyl quinic acid implying to be a cell-permeable and orally active drug. The bioactivity scores indicated that the compounds to be highly active. The binding affinities were checked with the wound pathogenic proteins such as Elastase, Glycogen synthase kinase-3β, gelatinase, and collagenase. The compounds that fall within the drug-likeness limit were further evaluated for ADMET properties and predicted that majority compounds are nontoxic and easily absorbed. The docking score ranged from -1.56 kcal/mol to -9.65 kcal/mol which exhibited the strongest binding affinity. The effective binding of compounds like epiafzelechin, betulin, kaempferol-7-O-Glucoside, linoleic acid, chlorogenic acid, and quercetin with these proteins provides evidence for further research to elucidate the underlying mechanism that promotes wound healing of Hygrophila auriculata root.

Hepatoprotective Plants used in Ayurveda System- A Review

By: Jyothi S.T , Niranjan M.H

Page No : 83-91

Abstract
Liver is an essential organ of our body. Bile secretion, detoxification, metabolism of fat and carbohydrates, storage of proteins, vitamins, iron and glycogen are the vital functions of the liver. Liver involves the biochemical pathways like supply of nutrients, growth, reproduction and production of energy. Liver injury is caused by certain antibiotics, carbontetrachloride, chemotherapeutic agents, thioacetamide, chronic alcohol consumption, antitubercular drugs, autoimmune diseases and microbes. Corticosteroid and immunosuppressive agents are used as drugs but they have adverse effects. Though these are developments in allopathy, there is no effective medicine that enhances hepatic function and protects liver. In Ayurveda system, plant materials have been used to protect liver injuries. Herbal medicines have gained popularity because they are easily available, safe, efficient and cost effective. The current research work laid down avenues to the production of novel herbal medicines for jaundice and reports the work on Ayurveda plants that have been proved and tested in hepatotoxicity.

Abstract
Commiphora wightii has massive economic value and a wide array of medicinal uses in both ancient and modern therapeutics. It has been observed that the number of C. wightii populations in Rajasthan are declining substantially because of anthropogenic activities in the form of over-exploitation for resin and fuel. Very limited molecular studies have been reported on the molecular characterization of Commiphora wightii at national and international level. The present investigation aims to assess the genetic diversity within and among different populations to determine the relationship of genetic variability with geographical distribution of Rajasthan and to offer genetic resource information for future meaningful implementation of conservation programs applicable for C. wightii. The present study comprised of 11 RAPD markers generated 37 loci of which two were polymorphic with an average 4.85% DNA polymorphism. The maximum polymorphism (33.33%) was detected for OPU-8 marker. Similarly, 9 ISSR markers generated 47 loci of which 10 were polymorphic with an average 22.11% DNA polymorphism. The maximum polymorphism (33.33%) was observed for ISSR marker 811P, 814P and UBC857. Jaccard’s similarity coefficient varied from 0.55-1.00 among the populations of Commiphora wightii using all the ISSR marker, while it ranges 0.20-0.95 for RAPD markers. The row dendrogram constructed using unweighted pair group method with arithmetic averages or UPGMA with a SAHN module of the NTSYS software which showed a phenetic representation of genetic relationships as revealed by the similarity coefficient for all the ISSR and RAPD profiles.

By: Sheeja George E , Aneykutty Joseph , Alphy Korath

Page No : 197-202

Abstract
A protocol was standardized for large scale propagation through multiple shoot proliferation from the basal buds of Echinodorus argentinensis, an ornamental aquatic plant. Explants were treated for 15 minutes with commercial bleach (containing 0.825% Sodium hypochlorite as active ingredient) which was diluted with distilled water to a concentration of 15%; and were then dipped for a second in 100% ethanol to obtain axenic cultures. The axenic basal buds initiated shoot formation within a week when cultured on full strength Murashige & Skoog medium (MS medium) supplemented with 1.0 mg/l 6-Benzylaminopurine (BAP). Number of shoots produced per explant was maximum (2.5672 shoots per explant p< 0.05) on MS medium supplemented with 1.0 mg/l BAP. Shoots were elongated considerably in all the media tried for shoot multiplication and maximum elongation (2.87 cm, p< 0.05) of the in vitro developed shoots was observed on MS medium supplemented with 1.0 mg/l BAP in combination with 0.1 mg/l Naphthalene acetic acid (NAA). Root regeneration was observed on all the shoot regeneration media and the highest number of roots/shoot (3.4568 roots per shoot) was obtained on MS medium devoid of any kind of plant growth regulators. The plantlets developed in vitro were subjected to acclimatization procedure and were finally planted in the aquarium. The protocol is ready for commercialization.

By: Thokchom Sonia Devi , Padmaraj Gajurel , Sorokhaibam Sureshkumar Singh

Page No : 203-211

Abstract
Young and fresh banana pseudostems of (Musa sp.) locally known as “Laphu” (Manipuri) are sold in the local markets and consumed as a common vegetable in Manipur. Despite high economic value and consumption, the nutritional values of banana pseudostems have not been studied. The present study evaluated the nutritional values and antioxidant activity of four highly consumed banana pseudostems [MN13 (Meitei Hei), MN14 (Maring Hei), MN15 (Ningol Hei) and MN20 (Ching Laphu)] found in different parts of Manipur. Two of the cultivated banana pseudostems (MN13 and MN15) were identified as Musa acuminata, MN14 as Musa hybrid cultivar and MN20 as Musa balbisiana of the family Musaceae. The total sugar (0.99 %), reducing sugar (0.57 %), starch (39.22%) and amino acid (23.94 μg/mg) contents were recorded highest in MN14. Non-reducing sugar (0.57 %), crude protein (12.84 %), ash content (30.63%), total phenolic content (23.31 ug GAE/mg) and flavonoid (15μg RE/mg) were found highest in MN20. Among minerals, the highest values of N content was recorded in MN20 (2.05%), P in MN13 (400.78 mg/100g), K in MN14 (42.88 mg/100g) and Na (1.14 mg/100g) in MN15. The antioxidant properties of the pseudostems were found to be very low in all samples as compared to cow pea (31.56%), ascorbic acid (65.86%) and gallic acid (69.2%). The present study reveals that the two banana pseudostems, MN14 (Musa hybrid cultivar) and MN20 (Musa balbisiana) were found to possess the highest nutritional contents based on mineral and dietary values. Further, studies may lead to the development of a suitable management strategy for conservation and sustainable utilization of MN20 as an important vegetable in the future.

Pharmacognostical Assessment, Antioxidant Ability and Determination of Phytomolecules using GC-MS in Gloriosa superba Linn

By: Anupriya Singh , Ashwani Kumar , Dev Nath Singh Gautam

Page No : 219-228

Abstract
Gloriosa superba Linn (family Colchicaceae) is a tendril climber with cylindrical and V or L shaped rhizomes that has received much attention due to its ancient pharmacological uses and being a rich source of colchicine. The pharmacognostical profile of leaf, stem and rhizome were analysed to assure the grade of raw material in the proposed investigation. Moreover, the antioxidant capacity of ethanolic rhizome extract of G. superba (EREG) was assessed using DPPH radical scavenging assay. Simultaneously, we have evaluated the phytochemical profile of EREG by GC-MS and total phenolic content was performed as well. Transverse section (TS) of rhizome revealed thin layer of brownish scales that fabricate the outer skin. In addition, the cortical area made up of homogeneous fleshy and parenchymal cells filled with starch granules which is one of the superabundant diagnostic features of this plant. Pharmacognostical profile of leaf, stem and rhizome of the plant demonstrated the evidence of authenticity of this plant. Anti-scavenging capacity (IC50) and total phenolic content was 77.20% and 9.54 mg, GAE/g, respectively. The GC-MS library identified two phytoconstituents as diethyl phthalate (100% peak area) and arsenous acid, tris(trimethylsilyl) ester (22.68% peak area) whose vast benefits are reported in the fields of pharmaceuticals, industry and personal care products. Frivolous research work in the field of pharmacognosy, antioxidant ability and instrumental analysis for phytomolecules provides a vast avenue for research on G. superba.

In vitro Flowering in Aerva lanata (L) Juss. Ex. Schult

By: Nagaveni C , Rajanna. L.

Page No : 229-234

Abstract
Aerva lanata (L.) Juss. ex-Schultz, is a medicinally important herbal plant with many medicinal properties like the antihyperglycaemic, lithotriptic, urolithic, antibiotic, antihelmintic, antihyperlipidemic, antimicrobial and hepatoprotective activity that intrigued us to study and propagate this plant. As the plant displayed challenges in propagation by conventional methods, especially during the off-season, the in vitro multiplication method was deployed. During this experimentation, in vitro flowering for two consecutive years both during the on-season and off-season was recorded. L2 media fortified with 2.5 mg/L IBA, and 1.5 mg/L BAP emerged as the best media for proliferation and direct organogenesis. Resultant shoots were subcultured onto similar media fortified with 1 mg/L GA3 to get elongated inflorescences. As flowers and inflorescences are of great medicinal importance, these results aid in sustaining the plant during the off-season and find its application accordingly.

Induced Morphological Viable Mutations in Mung Bean (Vigna radiata L. Millisp.)

By: Asha Rani

Page No : 1-7

Abstract
To find the viable morphological mutations in mung bean seeds of two varieties of green gram (Vigna radiata) i.e. Narendra mung-1 (NM-1) and Pantnagar mung-2 (PTM-2) were obtained from Pantnagar seed department, Pantnagar University, Pantnagar. These mutations occur due to the toxic effects of heavy metals which were present in city waste water. This effluent was collected from the B.D.A. colony nalah situated near Gulabrai Inter college of Bareilly city. The concentrations of the heavy metals such as copper, zinc and lead were found 7.500 mg/l, 7.270 mg/l and 3.740 mg/l respectively in city waste water. Different concentrations (80%, 90% and 100%) of the effluent were prepared to treat the mung bean seeds.
In first (M1) generation the phytotoxic effects of effluent on different growth parameters were observed. The seeds of M1 plants were collected and sown on plant to row progeny basis to raise second or M2 generation. Different type of viable morphological mutations were recorded in second (M2) generation. A wide range of viable mutants on seedling length, appearance, leaf number, shape and size, maturity pattern , yield were isolated in the M2 generation. Synchronous, early maturing and high yielding mutants are agronomically desirable which may be utilized in future breeding programme. Spectrum and frequency of these viable mutants were calculated. It has been observed that frequency of viable mutation increased with increasing concentrations of heavy metals. The heavy metal treatment showed increase in induction of viable mutation frequency and it reached to 3.255 in 100% ZnSO4 in PTM-2.

Depiction and Annotation of Hypothetical Proteins from Oryza sativa L. by Relative Screening in Seek of Rare and Nifty Proteins

By: Arpita Banerjee , Monali Bhattacharjee , Debapriya Das , Renia Mullick , Sujata Dhar (Dutta) , Debleena Roy

Page No : 9-19

Abstract
Rice (Oryza sativa L.) of the family Poaceae has various genomes that are uncharacterized for their biochemical, biophysical, and/or cellular functions, are identified as Hypothetical Proteins (HPs). In this study, a comparative in silico pipeline has been used for the identification and functional annotation of 10HPs of O. sativa obtained from NCBI database. The structure, function, subcellular localization and interacting partners of the proteins were analysed along with orthology prediction to the hypothetical proteins of the data set. 90% successful annotation was done where most of the annotated HPs have functionally significant domains and protein superfamilies. Majority of the proteins were predicted to be Enzymes. Subcellular localization is a vital step for effective protein identification as subcellular localization of HPs elucidates their cellular mechanism. Most of the proteins were localized within the nucleus followed by cytoplasm, chloroplast, mitochondria, plasma membrane, extracellular matrix. No signal peptide was predicted. Mainly, the proteins had their closest orthologous members belonging to other species of Oryza. Functional analysis has revealed the role of few HPs in both biotic and abiotic stress management in the plants. The consequence of this research may be beneficial for outlining general set pipeline or etiquettes for an improved perception of the function of HPs in physiological development of several plant system. The understanding of the structure and function of these important proteins and their binding sites would be beneficial in understanding their role in metabolic pathway and in docking studies for aiding in the drug discovery.

Proline Metabolism in Two High Yielding Groundnut Cultivars that Differ in their Drought Tolerance

By: K.V. Madhusudhan , C. Sudhakar

Page No : 21-29

Abstract
In this study, we compared the effects of drought stress on proline metabolism, glycine betaine and lipid peroxidation in two groundnut (Arachis hypogaea L.) cultivars, K-6 and JL-24, that are droughttolerant and drought-susceptible, respectively. As RWC decreased over time, leaf dry weight values also decreased across all stress regimes and cultivars. In the leaves of both cultivars, pyrroline-5- carboxylate reductase (P5CR) was upregulated in response to water stress, while proline oxidase (POX) and pyrroline-5-carboxylate dehydrogenase (P5CDH) were downregulated. These results imply that the induction of proline levels during groundnut development is associated with the elevation of proline synthesis enzyme (P5CR) and the downregulation of proline degrading enzymes (POX and P5CDH) that contribute to the plant’s decreased sensitivity to drought. Proline levels are greater in cultivar K-6 than in cultivar JL-24, which may be attributed to increased P5CR rates and less inhibition of POX and P5CDH. At all stress levels, the groundnut cv. K-6 accumulated more glycine betaine than the cv. JL-24. Malondialdehyde (MDA) is an indicator of lipid peroxidation, and in cultivar JL-24 it was found in significantly higher concentrations than in cultivar K-6. Dry mass buildup and physio-biochemical responses differed across cultivars and were based on the intensity of the stress. Tolerance levels of these two cultivars were compared.

Starch-based on Electrospun Nanofibrous Scaffold Incorporated with Bioactive Compound from Mollugo nudicaulis for Wound Healing Application

By: Mani Panagal , Siva Shankar Raj

Page No : 31-41

Abstract
The aim of this research was to develop nanofibrous scaffolds using starch and incorporating 12-(10-carboxydecanoyloxy)-12-oxododecanoic acid (Compound-1) from the ethanolic extract of Mollugo nudicaulis. Compound-1 was added to starch solutions at different concentrations (0, 20, 30, and 40% v/v) and transformed into nanofibers through electrospinning. The resulting electrospun fibers were analyzed for their morphology, size distribution, thermal stability, FT-IR spectra and wound healing potential. The nanofibers loaded with compound-1 exhibited a uniform morphology and had average diameters ranging from 76 to 98 nm. Moreover, the compound-1 encapsulated within the nanofibers demonstrated higher thermal stability compared to the free compound-1. FT-IR analysis revealed interactions between the starch and compound-1. Notably, the nanofibers loaded with 40% compound-1 exhibited significantly enhanced viability in HaCat cells. Western blot analysis showed increased expression levels of VEGF and PDGF proteins, suggesting that the developed nanofibers could promote angiogenesis and cell proliferation, thereby potentially accelerating the wound healing process. Based on these results, it can be concluded that the developed starch-based electrospun nanofibrous scaffolds, incorporating compound-1 from Mollugo nudicaulis, possess potent wound healing properties by activating the VEGF and PDGF signaling pathways. Nevertheless, further in vitro and in vivo studies are necessary to validate these findings.

Antioxidant and Acetylcholinesterase Inhibitory Activity of Basella alba Leaves

By: Vimal B. Jayswal , V.H. Patel , Neeta R. Dave

Page No : 43-48

Factors such as oxidative stress and reduced acetylcholine level have been implicated in Alzheimer’s disease. Green leafy vegetables exhibit neuroprotective activities by various mechanism, one of them being inhibition of acetylcholineesterase (AChE). Inhibition of AChE activity has been accepted as an effective treatment for neurodegenerative disease. AChE inhibitory activity prevents it from breaking down acetylcholine in the brain and improves acetylcholine concentration which leads to increased communication between the nerve cells. Some medicinal plants like Basella alba leaves (BAL) have been found to contain numerous phytochemicals with potent antioxidant effects. The majority of these component phytochemicals scavenge free radicals thereby neutralizing their injurious potentials on body tissues. BAL is an edible perennial vine found in tropical Asia and Africa, known as vegetables containing mucilage. The objective of this research is to estimate antioxidant capacity and AChE inhibitory activity of BAL. The total phenolic compounds, antioxidant capacity (FRAP, DPPH, ABTS, RPA) and AChE inhibitory activity of BAL were studied which results into total phenolic and flavonoid content of dried BAL was 664.49 mg GAE/ 100 gm and 950.52 mg RE/ 100 gm whereas total antioxidant capacity using FRAP, RPA, DPPH and ABTS was found to be 695.58, 429.17, 204.50 and 27.08 mg TE/ 100 gm, respectively. IC50 of fresh BAL for AChE inhibitory activity was 20.02 mg while that of positive control (tacrine) was found to be 0.008 mg. BAL have good antioxidant capacity and AChE inhibitory activity.

Page No : 95-105

Abstract
This study was conducted on five wild tuber plants named Dioscorea alata, Dioscorea pentaphylla, Dioscorea bulbifera, Dioscorea deltoidea and Dioscorea bellophylla belonging to the family Dioscoreaceae which are edible and are eaten by the local people of Hamirpur district Himachal Pradesh. Collected samples of the selected underutilized Yam plants from different regions of the study area were analyzed for their mineral nutrient content. Twenty-one elements were found: Aluminium, Barium, Bromine, Calcium, Chloride, Copper, Iron, Potassium, Magnesium, Manganese, Molybdenum, Sodium, Niobium (columbium-Cb), Nickel, Ruthenium, Rubidium, Sulphur, Silicon, Strontium, Titanium and Zinc. However, maximum K, Mg, S, Mn, Cu, and P were recorded in Dioscorea alata, Ca in Dioscorea bulbifera, Fe and Zn in D. pentaphyla. Based on the chemical evaluation, it was observed that tubers of D. alata, D. bulbifera, D. pentaphyla, D. deltoidea, and D. bellophylla might be suggested for commercial cultivation. However, minor information is available regarding its edible properties and nutritional requirements to the modem civilization. Present knowledge is not enough to generalize for all types of exploited plants available in the basket of the Himalayan region. However, it can be helpful to optimize more research to promote food security for humanity from starvation and malnutrition.

Abstract
Breast cancer is the major risk factor for mortality globally. Medicinal plant extracts were investigated as a potential source for breast cancer therapy. The current work aims to assess the intracellular ROS production and apoptosis induction by Alstonia scholaris Linn (A. scholaris) leaf extract in breast cancer cell lines. Column chromatography was used to purify bioactive components from an A. scholaris Linn methanolic extract. Fraction with a significant concentration of phytochemicals was utilised for further investigation. The results of DCFH-DA staining revealed a substantial rise in intracellular ROS levels in A. scholaris Linn-treated cell lines. The dual staining technique (AO/EtBr) was used to examine apoptotic changes. Treatment with A. scholaris Linn substantially enhanced the rate of apoptosis in breast cancer cell lines. Furthermore, enhanced p53 gene expression, downregulation of Bcl-2 and BRAC1 genes, and reduced TNF-a and IFN-l concentrations in A. scholaris Linn treated cancer cells demonstrated its anticancer activity.

By: Roshan K. V. Remesh , Jyothish Madambikattil Sasi , Biju Dharmapalan , Dhanya D.S

Page No : 129-135

Abstract
Eryngium foetidum L., a biennial herb, is extensively employed as a medicinal plant in many tropical countries. Its cultivation as a spice plant has gained prominence in India, Vietnam, Australia, and other geographical locations. Moreover, this botanical specimen exhibits a wide array of ethnomedicinal applications, encompassing the treatment of thermal injuries, otalgia, pyrexia, hypertensive disorders, gastrointestinal sluggishness, convulsive episodes, bronchial spasms, abdominal discomfort, helminthic infestations, reproductive impairments, snake bites, enteric disturbances, and malarial infections. The objective of the present study was to establish the optimal nutritional conditions required for shoot multiplication. To achieve this, axillary buds were employed as the explant, and various media and plant growth regulators were tested to determine the most effective regeneration method. Out of the various concentrations of Murashige and Skoog (MS) media and hormones that were tested, the most effective plant regeneration, with a success rate exceeding 95%, occurred on a half-strength MS medium enriched with 1.0 mg L-1 of benzyl adenine (BA) and 0.1 mg L-1 of indole-3-acetic acid (IAA), resulting in the development of 5 shoots per explant. Subsequently, these shoots generated in vitro were successfully established with roots (85–100% success), and they were then transplanted to an experimental field with an efficiency rate of 65%. Overall, this study provides an optimized medium for the micropropagation of E. foetidum.

Abstract
Plant kingdom have enormous chemicals contained in them. From the very ancient time till nowadays, people utilize these medicinal properties of plants, for the treatment of many diseases. Traditional medical sciences like Ayurveda, Unani, and traditional manuscripts provide us with the knowledge of how different plant parts are used for the treatment of various diseases. Ethnic groups and indigenous people of rural Murshidabad district and West Bengal use these ethnomedicinally important plants for treatment. The information about the importance of medicinal plants is transferred from generation to generation since ancient times. The aim is to screen out the different secondary metabolites present in each of the samples. Secondary metabolites are not primarily used during the life cycle of plants but used for their defense or other activities. These secondary metabolites have several beneficial aspects on human health. The secondary metabolites which are screened out mainly from the angiosperm families, which are abundant in Murshidabad district. Out of 25 species of angiosperms 10 species are encountered in the Murshidabad district, West Bengal, India. The plant samples are collected from the different localities and different parts are used, and extraction is done by organic solvents and distilled water. The extracted samples are then used for the screening of the secondary metabolites. Secondary metabolites screened out from these 10 species are Tannins, Phenolics, Alkaloids, and certain Glycosylated forms. These secondary metabolites have been reported to have various health benefits like antiseptic, analgesic, nervous system regulation, antioxidant properties, hypoglycemic, and immunomodulatory activities.

Net Zero Roadmap: A Global Pathway to Keep the 1.5°C: Global Biofuels Alliance Led by India at G20

By: Ashwani Kumar

Page No : 187-198

Abstract
Climate change is long term fluctuation in temperature, precipitation, wind and all other aspects of Earth’s climate. The Intergovernmental Panel on Climate Change (IPCC), a UNEP body formed under WMO is the leading international body for the assessment of climate change. For the first time in human history, concentrations of carbon dioxide (CO2 ), the primary global warming pollutant, hit 400 parts per million (ppm) in our planet’s atmosphere. IPCC has prepared a report on climate change, land degradation, sustainable land management, food security and greenhouse gas fluxes in terrestrial ecosystems. Humanity will overshoot the Paris Climate Agreement’s 1.5°C ‘safe’ guardrail on average global temperature rise. The report suggests that if no significant policy changes are undertaken the world will be warm by 4 degrees Celsius, which is what scientists are nearly unanimously predicting will happen by the end of the century. Recently, during the G20 held in India a Global Biofuels Alliance (GBA), an India-led ‘field-to-fuel’ initiative to develop and deploy biofuels as a green pathway for energy transition, job creation and economic growth was initiated. Recent efforts have focused on the development of renewable alternatives to fossil fuels, and cellulosic biomass has great potential to contribute to the demand for liquid fuel. Algal biofuels are in the nascent stage of development. A review of the present situation shall be presented.

Ceropegia Threatened and Less Known Genus of Rajasthan

By: Pooja Mangal , Yogita Solanki , Papita Choudhary , Shikha Gupta , Amit Kotiya

Page No : 203-215

Abstract
Ceropegia L. is a genus of tuberous plants and it belongs to family Apocynaceae that is comprised of 244 species worldwide. It is considered to be xerophytic because of its escape mechanism against the hot period by perennial tubers. Its tubers are edible and pharmacologically important mainly due to the presence of a pyridine alkaloid ‘Cerpegin’. Habitat destruction, over exploitation, anthropogenic activities and poor seed germination are major intimidations to the survival of this plant which have caused their decline in the wild and lead it to the endangered plant category list. This review provides comprehensive information on the distribution, taxonomy, phytochemistry, importance, IUCN status, and protocols for various in vitro regeneration approaches.

Frederick Robert (Bob) Whatley (1924-2020): Co-discoverer of Photophosphorylation in Chloroplasts and much more

By: Govindjee Govindjee

Page No : 23-29

Abstract
I present here a personal reminiscence of the life and research of Frederick Robert (Bob) Whatley (January 26, 1924–November 14, 2020). He was responsible for showing that chloroplasts are complete units for oxygenic photosynthesis and that ‘photophosphorylation’ is what is common between anoxygenic and oxygenic photosynthesis. He had an innovative nature and exploited many biophysical and biochemical techniques to understand, in depth, the regulatory nature of photosynthesis. Bob Whatley was a self-sufficient, thorough, quiet, and confident scientist, but he was ‘self-effacing’ and never ever “blew his own horn”. My presentation is mingled a bit, at places, with my own thoughts – to give it a ‘personal’ touch.

Symptomatic treatment, supportive care, isolation and experimental measure are the most important ways to manage this disease. However, 81% of the COVID-19 patients showed mild-to-moderate symptoms such as fever, cough, nasal congestion, fatigue, sore throat, loss of smell and loss of taste etc. Patients with mild-to-moderate symptoms may not need hospitalization because most of them will be able to manage their sickness at home through medication or supportive care. It will be useful to take both preventive measures and substances that boost the immunity while rest at home. Ministry of AYUSH in India recommended several approaches for preventive health care to boost immunity and respiratory health: following yoga and meditation plus intake of a few medicinal-plant-based compounds such as those from turmeric (Curcuma longa), cumin (Cuminum cyminum) and coriander (Coriandrum sativum) etc., once or twice a day. C. longa has been one of the most commonly used remedy for symptoms during COVID-19 pandemic in India. Based on existing scientific evidences, C. longa has been proved to be a potent antimicrobial, anti-inflammatory, immunomodulatory and antioxidant source, as well as a medicinal plant effective for respiratory disorders. In this review, scientific evidence of C. longa phytochemicals responsible for pharmacological activities are presented using in silico, in vitro and in vivo models. This review also discusses the disease COVID-19 and its causative virus SARS-CoV-2.

Abstract
The palm tree, Borassus flabellifer Linn., is an erect and celestial tree with more than 800 diverse applications. It is the official tree of the Indian state, Tamil Nadu. The aim of this study was to investigate the antidiabetic and antioxidant properties of Palmyra underground sprouts. Palmyra sprout was also tested for its anti-inflammatory properties. All the assays were conducted on powder of boiled Palmyra sprout extracts in chloroform. The antidiabetic potentials were assessed using ?-amylase, as a target enzyme. Colorimetric antioxidation potentials were determined by phosphomolybdenum method. The iron-ferrozine absorbance at 562 nm was used to calculate the metal chelating assay. An in-vitro protein denaturation inhibition assay was used to assess the anti-inflammatory property. The Palmyra sprout extracts inhibited ?-amylase, one of the key enzymes involved in starch digestion and blood glucose regulation. The Antioxidant potential of the sample was recorded as 96% and Fe2+ ion-chelating activities of the sample was also detected. The percentage inhibition of protein denaturation in this underground sprout was evaluated as 91.18. These results show that Borassus flabellifer Linn. underground sprout extract has antidiabetic, metal chelating, antioxidant, and anti-inflammatory properties, and hence has a lot of potential as a natural health product source.

By: Deepti Deshpande , Surekha Gupta

Page No : 99-102

Abstract
Algae are a diverse group of living organisms that are distributed in fresh as well as marine water bodies. Algae form an important part of aquatic food chain and food web and thus play an important role in regulating aquatic ecosystems. They are a good source of bioactive compounds, valuable food resource as well as potent pollution indicators. Taking this into consideration, an attempt was made to diversify the macroalgal species found on Bhuigaon beach during late winters in four consecutive years. Samples were collected during low tide, processed and preserved, herbarium specimens were prepared for identification of marine algae collected from the study site. Samples of sea water were also analysed for physiochemical parameters. A total of 08 different algal species were documented belonging to three different groups Chlorophyta, Phaeophyta and Rhodophyta. Effect of salinity, phosphates and nitrates on algal biodiversity was notable.

Extraction of Plasmid from Low-density Polyethylene degrading Bacterium and its Transformation into E. coli DH5a

By: N. K Kotwal , R. B. Vaidya

Page No : 103-110

Abstract
Improperly disposed plastics are a significant source of environment pollution of which about 3% of plastic material is recycled while remaining remains as litter. Littering not only threatens wildlife and marine life, but also causes considerable aesthetic nuisance. The hazard of discarding waste plastics like Polyethylene, so called “white pollution”, is becoming more severe. Improper methods of disposal like burying or burning of plastic materials release harmful or toxic pollutants into the environment thereby endangering the biosphere. The persistence of plastics in landfills is adding to the growing water and surface-waste litter problems. This research was therefore initiated to isolate bacteria that can degrade low-density polyethylene (LDPE), which is among the most frequent polymers found in the solid waste generated in urban areas. A total of 18 bacterial isolates were obtained that had the ability to degrade LDPE. 16s rDNA sequencing was used to identify the isolates. Further, based on polymer degradation potential of the isolates, one isolate Pseudomonas stutzeri strain CPO 4.206 was used for extraction of plasmid. The extracted plasmid was then transformed into E. coli DH5a.

Callus cultures from nodal explants were raised on Murashige and Skoog’s (MS) medium with Indole acetic acid (IAA, 0.5-2 mg/l) and 2,4-dichlorophenoxyacetic acid (2,4-D, 0.5-2 mg l-1). Shoot regeneration occurred from callus cultures inoculated on a medium supplemented with IAA (0.5-7 mg l-1) and for root induction different concentrations of IAA (0.5-2.0 mg l-1) and indole butyric acid (IBA, 0.5-2.0 mg l-1) were used. Out of the various concentrations used, 2,4-D (1.5 mg l-1) proved to be better with 90% response for callus formation. Similarly, 3 mg l-1 IAA showed highest number of shoots (18.6±0.40). These shoots on MS medium supplemented with IAA (1.5 mg l-1) gave maximum number of roots (5.40±1.98). For acclimatization, pure sand, garden soil and soil + compost (1:1) were used individually. The sand proved better by giving the survival rate 80%. The hardened plantlets were successfully transferred to the green house conditions and subsequently to the open field conditions. Different bioefficacies viz. antimicrobial using Agar Well Diffusion method and antioxidant using DPPH and FRAP methods along with total phenolic content were studied and compared with those of in vivo.

Page No : 127-132

Abstract
The objective of this experiment was to assess yield losses due to stalk rot in corn (Zea mays) after artificial inoculations through toothpick inoculations in susceptible variety ‘surya’ using paired plot technique in the southern districts of Rajasthan, India. Two field experiments were carried out in two different kharif seasons i.e. year 2019 and year 2020. Variety ‘surya’ were grown in field with 15 replications and inoculated with toothpick inoculations of Fusarium verticillioides. Samples of healthy and stalk rot infected plants were collected from each protected and unprotected plots, at harvesting stage. Result of field experiments revealed that rating and PDI were significantly lower in protected plots which are artificially inoculated with F. verticillioides, with average PDI 18.46% and Rating 2.84 in 2019, and of 19.12% PDI and 2.76 rating in 2020. PDI was significantly higher in unprotected plots that are 70.92 in 2019 and 70.94 in 2020. Significant loss in grain yield (gram/plot) was observed due to post flowering stalk rot (PFSR) in unprotected plots as compared to protected treatments were 23.66% in 2019 and 29.40% in 2020.

Page No : 133-138

Abstract
Banded Leaf and Sheath Blight (BLSB) disease of Maize Caused by Rhizoctonia solani f. sp. sasakii is one of the most severe disease causing serious yield losses each year. In recent years, Rhizoctonia solani is fitting more prevalent in agricultural areas where climate change is leading to higher temperatures. We conducted a experiment in which, a series of fungal collection, isolation and identification from the infected plant parts. The plant showed typical symptoms like the disease lesion are characterized by the presence of alternate bleached area or zones, which are initially water soaked and narrow purple brown bends oriented perpendicular to long axis of leaves or leaf sheath. The infected isolates may be seen on the affected tissues after reinoculation and produced mycelia growth and sclerotia on both plants and culture plates. On re-isolation it was found that the fungus was identical to the original isolate. It was observed that the infection was much higher in inoculated plants as compared to control.

Pheno-biological Diversity of Leaf Litter Macrofungi in Some Forests of West Bengal

By: Gouri Das , Parichay Chakraborty

Page No : 139-150

Abstract
In forest ecology and biodiversity, macrofungi occupy important place. Apart from soil nutrients, pH, soil moisture, depth of litter on the forest floor, a number of factors influence diversity of litter fungi as litter decomposition is a highly complex process mediated by various fungal taxa. In the present study physical and chemical attributes of leaf litter from different tree species in the forests of Dakshin Dinajpur district, West Bengal were observed and an assemblage of 11 macrofungal taxa belonging to 7 different families like Agaricaceae, Amanitaceae, Tricholomataceae, Omphalotaceae Marasmiaceae, Aphelariaceae, Psathyrellaceae have been found. These macrofungi were collected from Danga, Dogachhi, Kasiadanga, Barakasipur of Balurghat beat and Abhirampur, Asair, Erenda forestof Tapan beat. This investigation being the pioneering one in this area, also revealed high degree of host and part of the leaf specificity in some cases. The heterogeneity in the abiotic environment may have indirect or direct effect on the distribution of litter fungi in the litter profile. Interestingly, the occurrence of Aphelariaceae (Aphelaria sp.) was restricted to the litter layers of Erenda forest floor only. For systematic random sampling, field trips were conducted at 60 plots with 4 transects during summer, rainy, autumn and spring over last 3 years. All the collected samples were worked out thoroughly, identified and preserved in the laboratory. The data generated in the study will certainly enlighten the domain of mycological diversity of litter fungi.

Abstract
Tea plant is one of the major cash crops in Northeast India and tea leaves is a popular beverage cherished as a part of a healthy human diet. Tea plant being an economically important crop it is necessary to understand the soil fungal population as soil fungi are key drivers of plant productivity. This present study is conducted in the soil samples collected seasonally from the tea cultivated area of Mokokchung district, Nagaland, India. A total of 60 fungal species under 26 genera were isolated from the study site and colony forming units (CFU), relative density (RD), relative frequency (RF) and important value index were calculated. The highest fungal counts were recorded during the spring season with 8.2 x 106 CFUg-1 and lowest fungal counts were recorded in the winter season with 2.7 x 106 CFUg-1. Highest IVI was recorded in Aspergillus niger (8.09) followed by A. flavus (6.58). Dominance of Aspergillus may be attributed to the antagonistic nature exhibited by these genera against other fungi.

By: Ashwini Deshpande , Mahavir Gosavi

Page No : 159-163

Abstract
Arbuscular mycorrhizae (AM) are the obligate symbionts, forming natural, beneficial relationships with higher plants. About 80% of plants are colonized by AM fungi which belong to Glomeromycota (Family - Endogonaceae). In soil microorganisms, AM fungi are commonly studied because of their capacity to support plant tolerance under polluted and toxic conditions. The current study deals with the exclusive survey of fifteen industrial sites from MIDC, Dombivli (East). The sites were investigated to study diversity of AM fungi with respect to rhizosphere soil analysis for subsequent spore density and identification. Spores of Glomus, Acaulospora, and Gigaspora were observed. The observed species were also detected in root colonization analysis, using standard staining methods. The spore density was highest for Glomus. The species recorded and identified from genus Glomus are G. aggregatum, G. albidum, G. australe, G. deserticola, G. fasciculatum, G. fulvus, G. geosporum, G. intraradices, G. microcarpum, G. multicaule and G. occultum along with species of Acaulospora like A. foveata, A. mellea, A. scrobiculata and Gigaspora margarita.

Abstract
Wood-rot fungi are known to be saprophytic, they are grown on most of the organic and decaying matters. These fungi have an ability to produce coloured pigments in in-vitro cultures when they are grown in specific growth media. The pigment producing capacity of such fungi depends on the composition and pH of media. Various coloured compounds can be obtained by changing the concentration of component of growth media for such fungi. The most commonly used growth media for in-vitro culturing of woodrot fungi are Potato dextrose agar (PDA) and Potato dextrose broth (PDB) and Sabouraud dextrose agar (SDA) and Sabouraud dextrose broth (SDB). Current study conducted of Ganoderma lucidum, a commonly occurring wood-rot fungi, it has been observed that the production of pigment in G. lucidum was dependent on various growth media and their components. The fungus forms white patchy, non-pigmented colonies when cultured on PDA medium whereas it showed pigmented growth on SDA medium. Further, by replacing each nutrient component in the growth medium one by one, it has been determined that the component plays a vital role in pigment production by G. lucidum. It has been remarkably established that pigment production in the fungus is totally dependent on peptone concentration. Additionally, Nature of pigment has been studied by carbon and hydrogen ratio which has been in correlation with the substrate provided in the growth medium. The pigment obtained by the study were further evaluated for thermal and pH stability which showed promising results as pigment was unaffected till 60°C and there was no colour change detected with various pH solutions. Therefore, this study focuses on the potential applications of pigment obtained from G. lucidum as a natural pigment in textile and food industry by evaluating proper cytotoxic and structural analytical studies in future.

By: Rajib Borah , Leoris Malngiang , Nripemo Odyuo , Hiranjit Choudhury

Page No : 195-204

Abstract
Asymbiotic seed germination has revolutionised the commercial production of exotic orchids as well as conservation of rare and endemic ones. However, the success of the process largely depends on the sterilisation procedure adopted to disinfect the minute dust like orchid seeds. The present study incorporates the technique of centrifugation method to successfully disinfect the exposed seeds obtained from the dehisced capsule of Phaius tankervilleae, which is an ornamental orchid endemic to Northeast India. The seeds of P. tankervilleae showed 100% disinfection as well as germination efficiency (with 5% NaOCl and 8 mins exposure) with no risk of physical damage to the seeds due to the centrifugation process (4 mins at 4000 rpm under 4?C). Inoculated seeds showed the first sign of swollen embryos (PLBs) after 5 weeks of culture in Murashige and Skoog (1962) (MS) medium. PLBs obtained were subcultured on MS medium supplemented with different plant growth regulators for healthy proliferation and shoot multiplication. MS medium supplemented with 2 mg/L each of BAP and KN resulted in best overall shoot and root development. Therefore, the present study reports a simple yet effective sterilisation procedure to disinfect exposed P. tankervilleae seeds which is quick, easy and very efficient for mass scale propagation as well as ex-situ conservation of this valuable orchid species and other orchid species as well.

Abstract
Information about the impacts of different land-use systems on the physical properties of soil is essential for the sustainable utilization of existing soil resources. The main objective of this study was to examine the variation in selected physical properties across the different prevailing land-use systems in the Sub Humid Southern Plains and Aravalli hills of Rajasthan. A total of 120 composite soil samples were collected for laboratory analysis from barren, cultivated, agri-horticulture, horticulture, grass, and natural forest land-use systems by four different soil depths (0-20, 20-40, 40-60 and 60-80 cm) with five replications. The two-way analysis of variance (Two ways ANOVA) was used to test the effect of different land-use systems and soil depths on measurable soil physical properties. The results of the study revealed that the soil separates (sand, silt, and clay fractions) were not differed significantly across the land use systems as the texture is an inherent property of soil that cannot be changed easily by agricultural management practices. However, soil depth was affected significantly to the particle size distribution under studied land use systems. The mean bulk density of the soil varied from 1.51 to 1.62 Mg m-3 and the mean total porosity ranged from 38.56 to 41.77%. The highest plant available water (0.362 cm3 -H2 Ocm-3 Soil) and higher moisture content at field capacity (34.55%) and permanent wilting point (10.57%) were recorded in the natural forest land use system. All the six land-use systems confirmed distinct effects on soil properties as the highest superior soil properties were observed under natural forest land-use systems, followed by grassland, horticulture, agri-horticulture, and agricultural land-use systems, whereas the barren land use was showed inferior soil properties. The result of the study suggests that the incorporation of tree components on agriculture, barren, and grassland systems could decisive to improve the properties and sustainability of the soil in the study area.

Native Trees’ Resilience and Tropical Cyclones: A Case Study in Mumbai, Maharashtra, India

By: Babita Rana

Page No : 221-225

Abstract
Tropical cyclones with heavy rainfall and gusty winds cause severe damage to the environment, infrastructure, and economy of the affected area. This study focuses on the impact of major cyclones on vegetation with special mention of native as well as exotic tree species, particularly in Mumbai, Maharashtra, and elucidation of cyclone resistance traits in trees. Data collected from secondary sources of information supports the evidence that tree devastation was more in exotic species than native species. In Mumbai, as per the recent Brihanmumbai Municipal Corporation census, more than half of the 29.75 lakh tree population is of exotic origin. The most susceptible trees to bear the cyclone impacts such as defoliation, snapping of stems, and uprooting were Peltoforum, Gulmohar, Thespesia, Royal palm, rain tree, which were introduced to India hundreds of years ago. The common native species mango, banyan, peepal, and neem perform fairly well which underlines the importance of planting local species in cyclone vulnerable regions. The selection of proper plant species is very crucial to minimize the damaging effects of cyclones and heavy monsoons in coastal regions.

By: Soma Karmakar , A.K. Srivastava , T. Pandiaraj , Jyostna Tirkey

Page No : 227-233

Abstract
Tasar silk production is highly associated to natural ecosystem. Deterioration of natural ecosystem can directly affect the quality and production of tasar silk. Since regular use of chemical fertilizers reduce the fertility and total microbial biomass thus affecting soil health and productivity in tasar ecosystem. Hence, a field experiment was conducted at Central Tasar Research and Training Institute, Ranchi with an aim of improving the soil nutritional status using INM practices. The experiment was comprised 20 treatments including control which laid down in randomised block design with three replications. The soil samples were collected from each plot and analysed for different parameters. The study revealed that the pH of different experiment plots was acidic range (5.42 to 5.99). SOC was found to be higher in the treatment of 75% RDF with 25% VC + Azotobacter + PSB (1.33%) followed by 100%RDF with 2 kg/plant VC + Azotobacter + PSB (1.31%). The treatment T19 (495.5 kg ha?1 ) had recorded higher available nitrogen followed by T17 and lower in control. In case, the available phosphorus was found to be the ranges from medium to high (12.93 to 38.33 kg ha?1 ) in different treatments. In the present investigation, available potassium was observed in the range of 213.3 kg ha?1 ¹ to 513.3 kg ha?1 ¹ which resulted in medium to high range. All the micronutrients (Cu, Zn, Mn and Fe) in the experiment were found to be sufficient amount. Overall, the treatment that integrated chemical fertilizers with organic manure and bio fertilizers showed greater response to increase in soil nutrients content. Hence, the treatment i.e. 75% RDF with 25% VC + Azotobacter + PSB could prove a better and viable for nutrient demand of Tasar culture.

Effect of some Micronutrients on Biomass, Latex Yield, Sugar and Chlorophylls of Euphorbia antisyphilitica

By: Shobha Johari , Ashwani Kumar

Page No : 249-256

Abstract
E. antisyphilitica is a plant of bioenergy interest. It is a woody shrub tolerant enough to dry conditions of deserts. Earlier work on this plant revealed it suitable for soils of Rajasthan. This led us to study to enhance its growth and productivity so that its suitability for biofuel production can be ascertained. One of the aspects to increase plant growth is to supplement it with proper nutrients. Hence experiments were conducted with different concentrations of micronutrients manganese, iron and molybdenum in the form of manganous sulphate, ferrous sulphate and ammonium molybdate respectively. Plants were allowed to grow for four months and then harvested and analysed for parameters biomass, hexane extractables, sugars and chlorophylls. Biomass of this plant is useful as raw wood while its latex is a promising hydrocarbon yielding source which was extracted with hexane.

By: Sharda , Dheer Singh Shekhawat

Page No : 257-267

Abstract
Agriculture plays a key role in the development of any region. The development of human civilization was possible only after the mankind started agriculture. However the growth of agriculture in a particular region differs based on climate, soil, rainfall and proper agricultural practices over a period of time. The present study attempts to highlight the development of agriculture in the study area during the last 20 years. Attempts are also made to find out the effect of modern agriculture on ecology and to identify the effect of environmental changes on agricultural crops (Kumar et al., 2018; Kumar et al., 2020). During present studies two parameters have been considered, i.e., (i) agriculture development based variables and (ii) social development based variables. Charkhi Dadri District is one of the 22 districts of Haryana state in northern India. District Charkhi Dadri is located 112.6 km of India’s capital New Delhi and 295 km of Haryana capital Chandigarh. Charki Dadri comprises of two sub-divisions (Charkhi Dadri and Badhra) and two tehsils (Charkhi Dadri and Badhra) and one sub-tehsil (Bond kalan). District Charkhi Dadri is located between 28.5921?N Latitude and 76.2653?E Longitude respectively (https://charkhidadri.gov.in/). In four blocks of Charkhi Dadri district, Charkhi Dadri, Badhra, Jhojhu and Bond Kalan. Charkhi Dadri and Bond Kalan block have good soil fertility potential (https://charkhidadri.gov.in/) while in Badhra and Jhojhu most of the area is covered with sandy soil. Agricultural and social development in four blocks of Charkhi Dadri has been studied and results are presented.

Review on Plant Protease Inhibitors as Therapeutic Molecules

By: Sangeeta A. Godbole , Sopan N. Kharat

Page No : 277-288

Abstract
Plants contain several phytochemical compounds with capacity to exert therapeutic effects on human beings. One such group of molecules are the Protease inhibitors (PIs) which exert inhibitory activity towards several classes of mammalian, bovine, insect or microbial proteinases/proteases. PIs are polypeptides or proteins capable of forming reversible stoichiometric protein–protein complexes with specific proteolytic enzymes. This inhibits the catalytic function of proteolytic enzymes. Study of PIs is important to control proteolysis as it is the key to control the onset of several disease associated phenomena. Although initially, PIs were considered only as protein degrading enzymes, recent studies point them to be signalling molecules in biological activities.

In this article, various classes of plant protease inhibitors and their general mode of actions are discussed. The families belonging to the serine protease class of inhibitors (Serpins) are discussed in detail as these constitute an important class of therapeutically important molecules.

Data available on the use of PIs for treating a wide range of human diseases and disorders including the still incurable cancers is reviewed. Literature review confirms wide and successful use of Proteasome inhibitors (with similar activities to PIs) in treatment of haematological malignancies. Synthetic proteasome inhibitors are employed to inhibit the proteasome cascades and thus control disease onset and proliferation. Sharing the similar biological activities with the proteasome inhibitors, gives potential for the plant-based PIs to be experimented for similar uses. An attempt is made to report PIs from several plant species and their ongoing clinical trials to study their therapeutic actions.

Mitigation of Copper and Zinc Stress in Maize Plants by Inoculation with Azotobacter sp

By: Gopakumar Pillai , Soni Pinkesh Kumar Patel

Page No : 289-299

Abstract
Excessive concentration of heavy metals in soil affects the fertility and can have deleterious effects on plants and microorganisms thriving in the soil. With decreasing soil fertility and expanding population, the issue of sustainable food security is gaining momentum. Maize (Zea mays), one of the commercially important crops, is adversely affected by increased concentration of the heavy metals, Copper and Zinc. Plant nutrient requirements can be effectively met using bio fertilizers while reducing the dependency on chemical fertilizers. Azotobacter sp. has been proved to be an efficient bio fertilizer for a variety of crops. Two rapidly growing isolates of Azotobacter sp. (viz. Isolates A and B) were obtained from rhizospheric soil samples and their cultural, microscopic and biochemical characteristics were studied. Isolate A tolerated Cu and Zn concentrations till 0.4% while isolate B showed tolerance till 0.4% of Zn and 0.6% of Cu. Exopolysaccharide produced by isolate A showed 48% copper bio sorption. Both isolates exhibited plant growth promoting traits like IAA production, ammonia production and phosphate solubilisation. Tryptophan supplementation enhanced IAA levels. Maximum IAA production was seen with isolate A (41.49 µg/mL) followed by isolate B (40.55 µg/mL). Phosphate solubilisation was observed to be more effectively carried out by isolate A. Increasing concentration of Cu and Zn had a severe impact on germination and growth of plants. However, inoculation of isolate A and B supported growth of plants under Cu and Zn stress (maximum concentration 0.4%). Inoculation showed significant improvement in biomass content, relative water content and chlorophyll concentrations of maize plants under stress.

Minimizing Allelopathic Effect of Grewia optiva on Germination and Growth of Finger Millet Using Plant Growth Promoting Rhizobacteria

By: Rakesh Singh , Yashwant Singh Tariyal , J.S. Chauhan

Page No : 301-310

Abstract
Interaction among plant species has both beneficial and harmful effect on one or both the species. It plays an imperative role in the plant growth and survival. Grewia optiva (Bhimal) is widely grown fodder tree usually grown on boundaries of crop fields. The plant is reported to have allelopathic effect on crop growth but its importance as a fodder tree cannot be ignored. The present investigation is carried out with Plant growth-promoting rhizobacteria (PGPR) strains (Pseudomonas FP-11 and Bacillus BS-10) in alleviating allelochemical (biotic) stress of Grewia optiva (Bhimal) on Finger millet. Due to presence of Grewia optiva leaf extract there was inhibition in germination, reduction in seedling fresh and dry weight, root and shoot length of finger millet in contrast to control. This inhibition was recovered with PGPR treatment of Pseudomonas FP-11 and Bacillus BS-27. The results indicated that the seeds inoculation with PGPR strains under allelochemical stress significantly improved germination, plant growth, vigour and chlorophyll contents of leaf. The root length, shoot length, seedling length, seedling fresh and dry weight were also considerably increased by seeds treatment with PGPR. The plant growth promoting rhizobacteria (PGPR) Pseudomonas FP-11 strain and Bacillus BS-10 strain in combination could alleviate allelopathic effect of Grewia optiva on finger millet. Plant growth promoting rhizobacteria (PGPR) was observed replacing the use of chemicals in agriculture, horticulture practices. This is due to the emerging demand for minimizing harmful impacts and utilization of chemical products to the growing necessity of sustainable agriculture within a holistic apparition of development and to emphasize environmental protection.

Effect of Benzylaminopurine on Growth, Flowering and Postharvest Performance of Antirrhinum majus L.

By: Irfana Amin , Shabana Gulzar , Inayatullah Tahir

Page No : 311-314

Abstract
An experiment was conducted to study the effect of graded concentrations of Benzylaminopurine (BAP) on the growth, flowering and postharvest performance in Antirrhinum majus. Plants were raised in pot soil culture in 25 cm earthenware pots. BAP was applied as a foliar spray at 1, 5 and 25 mgl-1 concentrations. Plants were sprayed at 4, 12 and 16 weeks after transplantation. For each concentration there were five pots, besides a set of five pots each for the distilled water control and tween control. BAP at 25 mgl-1 concentration was effective in increasing plant height, fresh mass, dry mass and the number of laterals; besides resulting in the early emergence of floral buds. BAP particularly at 1 mgl-1 concentration was effective in enhancing the postharvest longevity of spikes and blooms in plain water. The results suggest that BAP as the foliar application can be effective in enhancing the pre and postharvest conditions of Antirrhinum majus.

By: C. Janani , B. Sundararajan , Nagamala , B. D. Ranjitha Kumari

Page No : 315-325

Abstract
Plant growth hormones assume important role in the development and conduct measure in the plant. The aim of this study is to examine the impact of gibberellic acid on morphological and biochemical factors of green gram under salinity stress. This study was carried out to determine the outcome of salt pressure (sodium chloride (NaCl), 0–100 µM) on the development and biochemical exercises of mung bean. Pre-dousing the seeds with 5 µM GA3 was appeared to improve the harmful impacts of salinity in most of the cases. The results of the study demonstrated that NaCl treatment evoked the decrease in development attributes of mung bean plant by diminishing the shoot and root lengths, number of leaves, and all out region of leaves just as new loads of shoot and base of mung bean plants. Moreover, centralization of 75 µM of salt altogether diminished photosynthetic colors content incorporate chlorophyll; decreases sugars; protein substance; all out free amino acids; phenols; starch; all out solvent sugars; and movement of cell reinforcement catalysts of superoxide dismutase (SOD), peroxidase, and catalase (CAT). In this examination, usage of grouping of GA3 (5 µM) lighten the effects of salinity to consider biochemical elements like shade content; decreasing sugars; protein substance; all out free amino acids; phenols; starch; absolute solvent sugars; and action of cancer prevention agent catalysts of SOD, peroxidase, and catalase.

A comparative GC-MS analysis of bioactive compounds in ethyl acetate fruit extract of Phyllanthus emblica L. growing in two phyto-geographically contrasting regions of west Bengal, India

By: Chandan K Acharya , Naureen S Khan , Nithar R Madhu

Page No : 343-355

Abstract
The Phyllanthus emblica L. has an interesting combination of ingredients. Fruit that grows in several parts of West Bengal, particularly the North Bengal Hill Slope and Jhargram, was researched using an ethyl acetate-based method. The spectrums of the individual components were compared to the library of previously identified spectrums using gas chromatography-mass spectrometry, and were done so on a Factor Four TM capillary column (VF-5 ms, 30 m, 0.2 mm id, 0.25 m film thickness; Varian, Middelburg, The Netherlands). Unsaturated alcohols such as Campesterol and alkanes such as N-Hexatriacontane were discovered as phytochemical components in the Jhargram fruit sample. Phenolic substances such as 1, 3, 3-Trimethyl-1-(4’-tri methyl silyl oxy phenyl)-6-trimethylsilyloxyindane, Phytosterol, and other organic compounds such as alkanes were also found. In the North Bengal sample, the phytoconstituents identified are alkenes such as 1-cyclohexyl-1(-4-ethyl cyclo hexyl) ethane and 17-pentatriacontene. The present study also revealed that the bioactive phytoconstituents like Lanost-8-ene, Stigmast-5-en-3-ol, oleate, 1,3,3-Trimethyl-1-(2’-trimethyl silyl oxyphenyl)-6-trimethylsilyloxyindane etc. in Jhargram Sample and heterocycle like Benzo (b) naphtho (2, 3, d) furan, steroid like Olean-12-ene and alcohol like Ergosterol in the north Bengal sample has a high percentage of abundance. The discovery of these chemicals is proof that the plant’s fruits may be used to treat various medical issues, a point that can be used as an argument in support of the plant’s agricultural and industrial value.

By: Haripriya. R , P. Thirumalai Vasan

Page No : 365-375

Abstract 
The tropical plant, Annona muricata has diverse health benefits and exhibits pharmacological activities such as antimicrobial, antioxidant and anticancer properties. The n-butanol fraction of the ethanolic leaf extract was derived from the plant using Soxhlet-extraction which is followed by qualitative and quantitative determination of phytoconstituents present in the leaf extract. The qualitative determination reveals the primary and secondary metabolites where anthraquinone was reported to be absent. The leaf extract was subjected to antimicrobial activity using Agar well diffusion assay which confirmed the antibacterial and antifungal property against Staphylococcus aureus, Pseudomonas aeruginosa and Aspergillus niger, Candida albicans respectively. The free radical scavenging property (antioxidant activity) of the phytochemicals present in the leaf extract was confirmed by DPPH assay and maximum inhibition of 87% of free radicals were observed at lowest concentration (100 µg/mL) and the IC50 value was found to be 59.72 µg/mL showing 50% of inhibition. The HPLC and GCMS analysis of the n-butanol fraction of ethanol extract of leaf confirmed the high abundance of phytoconstituents required for antioxidant and antimicrobial activity.

Abstract
More than 100 countries suffer from mosquito-borne diseases which are prevalent across the world. They are the known vectors for transmission of dengue, malaria, yellow fever, filariasis, Japanese encephalitis, schistosomiasis etc. Many of the insecticides that are currently used in mosquito control have harmful effects on human health and other non-target populations, they are non-biodegradable in nature, and also have a higher rate of biomagnification in our ecosystem. The spike in insecticide resistance on a global scale is raising serious concerns. Therefore, search for natural, eco-friendly alternatives such as bio-insecticides is imperative. In this study, Larvicidal activity of the essential oil obtained from the leaves of Callistemon citrinus was tested on the Dengue vector mosquito Aedes aegypti and Chikungunya vector mosquito Culex sp. Also, the chemical composition of the essential oil was studied using GC-MS analysis. Callistemon citrinus can now be considered one of such bio-insecticides which is easily available throughout India, with many therapeutic active constituents in its essential oil and 80-100% larvicidal activity..

Role of Rhizobia to Improve Zinc Phytoremediation by Legumes

By: Neha Batra , Ameeta Sharma

Page No : 389-402

Abstract 
High metal availability arising from mining and industrial activities, disposal of sludge or soil acidification, is an important problem in agricultural and forestry. Plants exposed to high concentrations of metals must respond in order to avoid the deleterious effects of metal toxicity at the structural, physiological and molecular levels. Plant strategies for coping with metal toxicity are genotype-specific and at least to some extent, modulated by environmental conditions. Physiology and biochemistry with regard to phytotoxicity, uptake and transport of Zinc and tolerance and its characterization were studied in Vigna unguiculata plants. Parameters studied were photosynthetic pigments, proline content, lipid peroxidation content, protein content, relative water content and antioxidant enzymes (SOD, EC 1.15.1.1; CAT, EC 1.11.1.6; APX, EC 1.11.1.11). Metal stress inhibits chlorophyll activity and induces alterations in protein level. Increase in CAT, SOD and APX activity along with RWC was seen at the earlier stages with the decline at the last stages of plant growth. An immense increase in the proline and MDA content was observed. This may possibly be due to either down regulation of photosynthesis or photo inhibition process. Further, Rhizobium was used as soil fertilizer to prevent the stress of Zinc on growing Vigna unguiculata. The experiment tolerance index of plants was increased in the presence of Rhizobium than in their absence in polluted soil. Our results demonstrate that cowpea plants perform better when amended with Rhizobium under metal stress, as indicated by a lower sensitivity to photoinhibition, proline accumulation and higher antioxidant enzyme activity.

By: Aadity Saitawadekar , Umesh B. Kakde

Page No : 403-409

Abstract
The two basic approaches to manufacture NPs are the top-down and bottom-up techniques. Bottom-up approach is the alternative approach to the physical method of synthesis of NPs, which has the potential of creating less waste and hence being more economical. Nanoparticles from green synthesis have been getting an increasing advantage due to it being a cost effective and eco-friendly method for nanomaterial synthesis. The present investigation focuses on the biological synthesis, characterization of biogenic nanoparticles using extracellular filtrate of Aspergillus flavus. The characterization of synthesised silver nanoparticles has been done using techniques such as UV-Vis Spectroscopy, Fourier transform infrared (FTIR), Transmission electron microscopy (TEM) and Nanoparticle tracking analysis (NTA). The maximum peak was observed at 426 nm in UV-vis spectroscopy after every 5 minutes. In order to identify the presence of functional groups in extracellular fungal filtrate which was used for bioreduction of silver and capping of silver nanoparticles, FTIR analysis has been carried out. The spherical aggregate shaped silver nanoparticles synthesized by A. flavus ranged from 7-50 nm confirmed in TEM as well as in NTA.

By: Gursimran Kaur Uppal , Aparna Patil Kose , Saiprasad Ajgaonkar , Suraj Sen , Nilesh Pal

Page No : 411-420

Abstract
In December 2019, cases of the new coronavirus disease 2019 (COVID-19), caused by a new betacoronavirus (SARS-CoV-2), were first reported in Wuhan, China. These cases were characterized by acute pneumoniaassociated symptoms, such as fever, dry cough, chills, shortness of breath, and muscle pain. On comparing SARS-CoV-2 with SARS-CoV, significant differences were observed in the sequence of the S gene of SARSCoV-2, including three short insertions in the N-terminal domain, changes in four out of five of the crucial residues in the receptor-binding motif, and the presence of an unexpected furin cleavage site at the S1/ S2 boundary of the SARS-CoV-2 spike glycoprotein. This insertion is a novel feature that differentiates SARS-CoV-2 from SARS-CoV and several SARS-related coronaviruses (SARSr-CoVs). The SARS-CoV-2 Spike (S) protein, which is the viral protein responsible for binding the ACE2 receptor on the host cell. Prior to and after attachment, the S needs to be activated by cellular proteases (e.g. furin, TMPRSS2), triggering the virus’ entry into the target cell. Presence of a multibasic site, an amino acid motif recognised by furin protease, and whose cleavage activates the S protein. Hence researchers are exploring furin inhibitors against SARS-CoV-2 infection. In our study we have performed virtual screening of natural and synthetic compounds with furin structure (PDB ID: 5JXH). The docking and ADMET results showed that Nafamostat, DAPI, Propamidine, Hydroxystilbamide compounds showed similar activity as per standard drug Diminizine (anti-parasitic drug). Nafamostat compound has shown highest binding affinity with -9.1 kcal/mol against the furin enzyme target and hence it could be considered as a potential inhibitor drug.

In-Silico Investigation of Phytochemicals as Antiageing Agents against Matrix Metalloproteinases using Molecular Docking Approach

By: Aparna Patil Kose , Shilpa N Potdar , Rupal A Mishra , Priyankal D Sharma

Page No : 421-428

Abstract
Photoageing is caused by the excitation of matrix metalloproteinases (MMPs) in the skin, which is caused by UV light causing a disruption in the balance between MMPs and inhibitors in our bodies, resulting in collagen degradation and, as a result, wrinkles development. Antioxidant phytochemicals are being researched to minimise the oxidation processes caused by photoageing. Molecular docking was used to choose the optimal phytochemical with the highest binding affinity for MMPs. The study was carried out on 100 plants effective against wrinkles out of which 30 common phytochemicals were selected showing antioxidant properties. These selected phytochemicals were further targeted against nine types of MMPs responsible for wrinkle formation using molecular docking approach. Further, protein optimization was carried out in GROMACS software to enable successful docking. The docking analysis was performed using PyRx tool and the docked structures were visualized using Discovery Studio 4.1 Visualizer. It was observed on the basis of docking score that beta carotene, rutin and luteolin phytochemicals showed highest binding affinity with the target protein (9 types of MMP). The differences in binding affinities among the proteins were discovered in this docking research various protein-ligand complexes which confirms the potential target for ageing in order to stop wrinkle development.

Molecular Docking Studies of Selected Phytochemicals as Potent Inhibitors for Parkinson’s Disease: Approach to Anti-Parkinson’s Drug

By: Shubham A Ghadge , Priyankal D Sharma , Ananya R Chavan

Page No : 429-436

Abstract
Parkinson’s Disease (PD) is neurodegenerative condition where persons suffers because of neuronal death caused by depleted dopamine levels which is neurotransmitter responsible for functioning of brain in substantia nigra (SN) part of mid-brain. To minimize this depletion of dopamine, phytochemicals having neuroprotective and antioxidant properties are studied. According to literature search 38 phytochemicals were selected showing neuroprotective and antioxidant properties. With molecular docking approach phytochemicals were docked against 6 selected Biological markers which are COMT, MAO-B, PINK1, BACE1, Alpha- synuclein, E3-PARKIN for Parkinson’s. The protein-ligand docking was performed using PyRx 0.8. Further interaction visualized on Discovery Studio Visualizer 21.1.0. The ligand Chrysin, Bicuculline and Hesperetin were showing best binding score against protein target. This docking study showed various protein-ligand interactions with varying binding energies. With some research, the best scored ligands can be used further to study their effects on in-vivo and in-vitro models.

In vitro Antibacterial and Antibiofilm Activity of Azadirachta indica Plant Extracts against Multi-drug Resistant and Biofilm Forming Staphylococcus aureus and Escherichia coli

By: A. P. Nagrale , V. A. Kamble

Page No : 437-443

Abstract
Multi-drug resistance of Escherichia coli and Staphylococcus aureus bacteria to a wide variety of antibiotics has been linked to unwise use of the same antibiotics against infections in food and pet animals around the world, as well as in humans. The major factor contributing to microbial resistance is the microbes’ biofilm formation which allows them to withstand in extreme environmental conditions and antimicrobial agents. In the current study, multi-drug resistant and the biofilm forming E. coli and S. aureus strains have been isolated from the different types of specimens. Commercially available antibiotic discs were used for the study of multi-drug resistance patterns in the isolated strain and also studied with disc diffusion assay. The antibiotic susceptibility and biofilm forming ability of 76 E. coli and 57 S. aureus cultures isolated from the clinical samples were tested. Apart from multiple drug resistance traits, biofilm production by the microbe is one of the phenomena which renders multiple drug resistance to the isolate as well. Susceptibility testing of different solvent extracts of plants, namely Azadirachta indica. The sensitivity of all the plant leaf extract was assessed by the well diffusion method and determined in terms of inhibition zone diameter. The inhibitory activity against the clinical isolates reflects an inhibition zone range of 10 mm to 40 mm. All of the above biofilm producing isolates showed varying degrees of antimicrobial activity.
