Drought tolerance research focuses on understanding how plants can survive and thrive in conditions of limited water availability. This involves studying the physiological, biochemical, and genetic mechanisms that allow plants to withstand periods of drought stress. Researchers aim to identify genes, proteins, and metabolic pathways involved in drought tolerance, as well as develop strategies for breeding or engineering crops that are more resilient to drought conditions. By enhancing drought tolerance in plants, researchers hope to increase agricultural productivity and improve food security in regions prone to water scarcity.
