Drought stress research focuses on understanding the physiological, biochemical, and molecular responses of plants to water scarcity. It aims to identify mechanisms that enable plants to cope with water stress and develop strategies to enhance drought tolerance in crops. Studies in this area often involve investigating the effects of drought on plant growth, photosynthesis, water use efficiency, and stress-responsive gene expression. The ultimate goal of this research is to improve crop productivity and sustainability in water-limited environments, as well as to contribute to global food security in the face of climate change.
