The aims of this study were to address the chemical profiles, antibacterial and antioxidant activities of acetone extract isolated from branches and leaves Jasminum annamense subsp. annamense for the first time. The chemical constituents of acetone extracts of studied samples were investigated by gas chromatography-mass spectrometry. There were a total of 24 components identified from the leaf extract, including lup-20(29)-en-3-one (27.93%), levodopa (19.68%), trans-cinnamic acid (7.58%), linolenic acid (6.35%) as the major compounds. Meanwhile, 26 components were reported from the branch extracts which are sorbitol (25.74%), lupeol (13.3%), cis-vaccenic acid (6.97%), glycerin (6.35%) and n-hexadecanoic acid (5.86%) were the main components. The two acetone extracts of J. annamense subsp. annamense exhibited antibacterial effect against Bacillus cereus, Escherichia coli, Salmonella enteritidis and Staphylococcus aureus based on disk diffusion assay. In addition, leaf and branch extracts of the studied species also display notable antioxidant activity in the ABTS assay with IC50 values of 311.75±3.39 and 664.46±3.732 µg/ml, respectively. This is the first report on the chemical and biological properties of J. annamense subsp. annamense and provides a promising perspective for developing good sources of antioxidant and antimicrobial compounds against both Gram positive and negative bacteria.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43684208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This stress leads to weakening of the immune system thus leading to higher susceptibility to other infections as well. This also includes the weakening of the respiratory tract leading to increased susceptibility of viral infections as in the case of COVID-19. Treatment for any kind of abnormality requires the identification of the key target proteins and pathways that are being altered. Withania somnifera is being used in the traditional medicinal system to improve health and longevity thus creating a sense of mental as well as physical well being. The present study utilises network pharmacological approach to predict the potential oxidative stress targets of the three major withanolides: withanolide A, withaferin A and withanone. Primarily, the targets of the individual withanolides were obtained from the Swiss target and DIGEP-pred databases and the GO terms and lead hits related to oxidative stress were retrieved from AMIGO2 database. Totally 40 correlative hits were obtained as anti stress targets of the withanolides, which were subjected to functional enrichment and protein–protein interaction analysis to study the enriched pathways underlying oxidative stress response. Further the eleven crucial targets of the four selected pathways were analysed using molecular docking analysis. A total of forty protein hits were obtained as oxidative stress targets of the withanolides. Further, the pathway enrichment of these forty target genes showed the AGE RAGE signalling pathway as highly enriched pathway. Therefore, the AGE RAGE signalling pathway along with its underlying pathways namely MAPK signalling pathway, FOXO pathway and PI3-AKT pathway were chosen among all the other enriched pathways. Further the molecular docking analysis of the eleven target proteins falling under these four pathways showed good docking scores of the withanolides with all the eleven targets with the highest interaction against BCL2.  From the above study, the biological targets and associated pathways of the withanolides have been retrieved.  Thus the in silico approach undertaken in this study explores the role of the key withanolides in the antioxidant potential of the traditional medicinal plant Withania somnifera.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44588561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight pairs of SSRs markers were used depend on their ability to separate between fig cultivars as mentioned in previous studies, six pairs of them gave amplified products in the polymerase chain reaction (PCR), while MFC3 and MFC6 primers did not give any amplification products. A total of 17 alleles were detected at six SSRs loci. The alleles number per locus ranged from 2 to 4 with  an average of 2.83 alleles/locus. The observed heterozygosity (Ho) was 0.33, while the expected heterozygosity (He) was 0.17. The mean value of genetic similarity was 0.69 where fig cultivars has separated into two clusters in Cluster Analysis, which confirms a significant genetic similarity between most of the cultivars. MFC1 and MFC2 loci gave about 0.67 and 0.61 PIC (Polymorphism Information Content) values respectively, which confirms their ability to study the genetic diversity of fig cultivars more than other loci. F1 and F2 cultivars greatly affect the quality of the fruits as paternity traits as Caprifigs. Tammozi cultivar has low values of its genetic similarity with the rest of the cultivars which reflect great difference between it and other cultivars. Generally, the challenges in this study were in characterizing unrecognized fig cultivars in southern Syria to distinguish between them as they were not certified in agriculture ministry in Syria because the lack in studies related to the same topic as these cultivars were not studied before, thus, we managed to make a significant contribution in certifying fig cultivars in Syria using SSR technique.","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47712148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to investigate the effects of three different explants for its regeneration potential, de embryonated cotyledon, immature zygotic embryo and nodal segments from a 30 year old neem plus tree were used. Half strength MS medium with benzyl amino purine (3 mg/L) and naphthalene acetic acid (0.5 mg/L) and casein hydrolysate (1 g/L) was effective in shoot bud sprouting from both nodes and cotyledons. Half strength MS medium fortified with TDZ (0.2 mg/L) was effective for induction of somatic embryogenesis from zygotic embryos. Shoot buds initiated from the cotyledons produced a maximum number of shoots per explants (4.33) which on further sub culturing induced maximum multiple shoots (15) on half strength MS medium fortified with BAP (1.5 mg/L), NAA (0.5 mg/L) and CH (400 g /L) and the nodal explants induced only 4-5 axillary shoots on further sub culturing. Even though immature zygotic embryos produced more number of somatic embryos per explant (24.97) within a short time (30-45 days), the plantlet conversion was poor (25.52 %).

Ligand analysis was performed and Phloretin was chosen as the experimental ligand and Bcl-2, NF Kappa B, Carbonic anhydrase I (CA-1), Inducible Nitric Oxide Synthase (iNOS), Endothelial Nitric oxide synthase (eNOS), Caspase 3, and Caspase 9 proteins were chosen as targets. Induced fit molecular docking was performed by the use of Glide 6.5 software (Schrodinger - 2015). The docked poses were further evaluated based on binding energy, Conformational changes, and the amino acid residues involved in the protein-ligand interaction. The docking results depicted that phloretin showed notable binding affinity especially with carbonic anhydrase I, ENOS, and INOS. It also showcased significant potential against Caspase 3 and NF Kappa, thereby showing its potential as an effective anti-cancer therapeutics. During this study, the Inhibitory potential of Phloretin was studied as a result of this molecular docking study.

Among the cereals, demand for maize is increasing year after year, but fluctuation in climatic conditions especially the temperature extremes is the current and future threat in maize cultivation. Each degree Celsius increase in global mean temperature causes yield reduction up to 7.4 per cent in maize. The high temperature stress impact at the reproductive stage affects grain filling rate and duration. Adaptation of maize crop to future warmer climatic conditions requires a better understanding of physiological responses to elevated temperatures. With this view, a pot culture experiment was conducted at the Department of Crop Physiology, TNAU, Coimbatore during the summer season of 2020. Two maize inbreds viz., UMI 1230 and CBM-DL- 322 were taken for the study and exposed to high temperature stress treatments viz., T1 - ambient, T2 - ambient+4°C and T3 - ambient+6°C (44°C) for 10 days during the reproductive stage to assess the changes in biochemical and yield traits. The ambient+4ºC treatment revealed that the maize inbred line CBM-DL-322 recorded lower malondialdehyde content with over production of antioxidant enzyme activity (superoxide dismutase, catalase and ascorbate peroxidase). Cob weight and seed set parentage showed a negative correlation with both elevated temperatures. It is concluded that the maize inbreds line CBM-DL- 322 performed better at an elevated temperature at ambient+4°C and recorded more cob weight (57.09g) compared to UMI 1230 inbred (43.56g).","PeriodicalId":16777,"journal":{"name":"Journal of Phytology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45735975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
