Chemical pesticides are frequently used to manage them. Due to their constant usage over many years, insect pests have become increasingly resistant to practically all kinds of chemical pesticides, which has increased the demand for alternatives. For effective and environmentally safe insect pest control, insect pathogenic fungi are seen to be a viable alternative to practically all kinds of conventional pesticides. However, the viability of this strategy is being constrained by the sluggish death rate and necessity of large conidial concentrations. The ability of these fungi to regulate insects has previously been examined, but more recent research has focused on their potential to operate as plant endophytes to protect plants from phytopathogens and enhance other elements of agricultural output. The significance of these entomopathogenic fungi as endophytes in the context of biological control is discussed in this article. Finding local strains of entomopathogenic fungi that can colonise endophytes and their possible utility in the management of disease-causing pests are the main goals of our research for this review.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":"68 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139534735","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 review article provides a comprehensive overview of seed priming techniques, their underlying mechanisms, and diverse applications in crop production during the recent years. The article introduces the concept of seed priming and its importance in optimizing seed performance, discussing various seed priming techniques including osmotic priming, hydro-priming, hormonal priming, and microbial priming. Each technique is described in detail, outlining the specific procedures and conditions involved, and their advantages and limitations are discussed. The underlying mechanisms of seed priming are explored, elucidating the biochemical, physiological, and molecular changes that occur during seed priming, and the interactions between priming substances and seeds. The article also provides an in-depth analysis of the applications of seed priming, discussing its positive effects on seed germination, seedling vigour, stress tolerance, and its potential for sustainable agriculture. This review article serves as a valuable resource for researchers, scientists and faculties working in the field of seed technological research and progressive farmers who can adopt this technology for enhancing crop yield. This article provides insights into the techniques, mechanisms, and applications of seed priming for optimizing seed performance and enhancing crop productivity in diverse agricultural systems.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":"88 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139440508","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 India, the genus is represented by 10 species, with two species reported from Western Ghats and Eastern Ghats, and the remaining eight species from the Northwestern Himalayas and Northeastern regions. This study reports the occurrence of Cheirostylis griffithii Lindl. in Manipur, Northeast India, which is a new generic record for the state. The taxon was discovered in Pudunamei village and identified based on herbarium specimens and available literature. Detailed morphological descriptions and measurements were made using living plant specimens. The taxonomic treatment includes information on plant characteristics, distribution, and a comprehensive list of Indian Cheirostylis species. The species is a terrestrial orchid with fleshy stems, lanceolate bracts, pubescent flowers, connate sepals forming a tube, and a 3-lobed lip with deeply laciniate lobes. The occurrence of Cheirostylis in Manipur expands its distributional range within India. The study contributes to the documentation of the orchid flora of Manipur, which encompasses a diverse range of orchid taxa.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139440034","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}

Kariyil, Priyanka Menon K., Hari Sankar V J","doi":"10.14719/pst.3016","DOIUrl":"https://doi.org/10.14719/pst.3016","url":null,"abstract":"In silico screening is a methodological approach, which is invaluable for rational drug design and the identification of potential therapeutic agents. In the context of antibiotic-resistant infectious wounds, molecular docking can provide a deeper understanding of how phytocompounds might interfere with bacterial virulence and antibiotic resistance. In this study, proteins involved in antimicrobial resistance and wound healing were docked against major phytoconstituents of ethyl acetate extract of Cissus quadrangularis (EACQ) and ethanol extract of Chromolaena odorata (EECO), two medicinal plants that have been traditionally used. Receptor structures for interleukin 6 (PDB id: 1n26) of human and mice, IL6 (Uniprot id p 20607) of rat, vascular endothelial growth factor (VEGFR, PDB id: 2ctw) for human, mice, rat and penicillin binding protein 2a (PBP2a, PDB id: 1vqq) of S. aureus were downloaded from the database of the RCSB protein data bank. The ligand structures were downloaded from PubChem compound database in structure data file (.SDF) format. The docking studies were conducted using Autodock4. and the results of the docking analysis were visualised using Discovery Studio Visualizer. The docking log (dlg) file, featuring an RMSD table, provides binding energy values in Kcal/mol for each molecule at its optimal docked postures, offering insights into structural accuracy and ligand-receptor interaction strength in molecular docking simulations. In silico analysis of ligands showed that squalene of EACQ and epilupeol of EECO had the least binding energy towards proteins of antimicrobial resistance and wound healing. Thus, these compounds could emerge as promising lead molecules against infectious wounds.","PeriodicalId":509766,"journal":{"name":"Plant Science Today","volume":"49 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139441295","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}
