Abstract Title:Elucidating the lipoxygenase-mediated defense responses in pearl millet against biotic pathogens

Biography:

Research Interest: Pearl millet (Pennisetum glaucum) is an essential staple in the semi-arid tropics. Because of its nutritional value and ability to withstand harsh environmental conditions, it is a crucial crop for populations dealing with issues related to food security. Pearl millet is gluten-free and has a low glycemic index, its potential as a wheat flour substitute is particularly noteworthy for celiac patients. This crop's relevance is highlighted by its capacity to withstand drought and high temperatures as well as its rich nutritional profile, which includes vitamins, zinc, and iron. However, its yield is seriously threatened by the effects of biotic stress, especially diseases like downy mildew caused by Sclerospora graminicola. The predicted losses can be rather significant, which emphasizes the urgent need for comprehensive research to identify pearl millet’s defense mechanisms against these infections. Lipoxygenases (LOXs) are crucial in this context, as they mediate various plant responses to stress. Research into LOXs in pearl millet could reveal insights into enhancing its resistance to biotic stress, ultimately contributing to improved yields and food security in regions reliant on this crop. Understanding these mechanisms could lead to better breeding strategies and disease management practices. Eight PgLOX genes were identified here, and classified them into two groups based on phylogenetic and structural analyses. Significant changes in transcript levels were seen when RT-qPCR was used for expression profiling under biotic stress.
