Research/Scientific Activity Overview With the dual challenges of a growing global population and climate change, enhancing crop production has become a critical priority in agriculture. Abiotic stresses, including drought, salinity, high temperature and heavy metals, are major contributors to crop loss worldwide. My research focuses on the physiology and molecular biology of abiotic stress tolerance in agronomically important crops, aiming to develop stress-resilient plants through physiological, biochemical, and molecular approaches. Key objectives include: *Development of Abiotic Stress Tolerant Crops: Investigating how plants respond to environmental stressors at the molecular and physiological levels to develop crop varieties that better withstand abiotic stresses. *Role of Mineral Nutrients in Stress Amelioration: Examining the role of essential nutrients in alleviating abiotic stress and enhancing crop resilience. *Antioxidant Machinery and Stress Signaling: Analyzing how antioxidant systems and signaling mechanisms react to oxidative stress induced by abiotic factors, such as drought, heavy metals, and salinity. Research involves crops such as Capsicum annuum, Solanum melongena, Brassica spp., Triticum aestivum, Zea mays, Oryza sativa, Hordeum vulgare, Avena sativa, Solanum lycopersicum, Pisum sativum, and Cicer arietinum. Specifically, the focus is on understanding the roles of antioxidant systems, photosynthetic efficiency, with a detailed analysis of ROS.
