As a part of the course, PBG 112 – Principles of Genetics and Cytogenetics (2+1), by the students of B.Sc., (Hons.) Horticulture (2023 Batch) at Adhiparasakthi Horticultural College, the study was undertaken on the behaviour of chromosomes at meiosis. In this context, we have observed the Pollen Mother Cell (PMC) and Microspores. For which, the inflorescence of rice was used as an experimental material for studying the behavior of chromosomes at meiotic cell division. Both the cells were observed at 40 X magnification.
The quest is continuous for effective health-promoting ingredients in the fields of culinary innovation and nutritional research. The increasing consumer demand for functional foods - those offering additional health benefits beyond basic nutrition has propelled researchers and food technologists to explore new, natural ingredients. Over the past decade, the commercial, academic, and governmental sectors have all shown a greater interest in the creation of functional foods. Consumers readily accept food items with health claims attesting to their functional potential to enhance health beyond the supply of vital nutrients, which probably lowers morbidity and mortality and improves the overall population quality of life.
Plants have been indispensable for their nutritional and health benefits, serving as primary sources of natural products used in pharmaceuticals, agrochemicals, flavors, fragrances, and more. The beneficial properties of plants are largely due to secondary metabolites, compounds essential for modern medicine and various industries. This article examines the role of microRNAs (miRNAs), small non-coding RNAs that regulate gene expression, in controlling the biosynthesis of these valuable secondary metabolites. The miRNAs influence plant developmental activities, stress responses, and various biological processes, including secondary metabolite production. By understanding and manipulating miRNA pathways, the production of these compounds can be enhanced. Effective techniques such as artificial miRNAs (amiRNAs) are widely used for targeted gene silencing and modification of small RNA biosynthesis pathways. The article discusses the potential of miRNA technology to revolutionize the production of plant-derived compounds, paving the way for innovations in medicine, agriculture, and industry through more efficient and sustainable practices.
Marine fisheries play a crucial role in the sustenance and livelihood of coastal communities worldwide. Women, who make up a significant portion of the workforce, are deeply involved in various activities across the fisheries value chain, from pre-harvest to marketing. However, their contributions often go unrecognized, and they face numerous challenges, including social, economic, and environmental constraints. This article explores the essential roles of fisherwomen in marine fisheries, the myriad challenges they encounter, and their transformative impact on the industry.
