Abstract
Tomato (Solanum lycopersicum) is greatly impacted by drought. Under drought stress, tomatoes produce an excessive amount of reactive oxidative species (ROS), which has a disastrous effect on tomato productivity and growth. One of the major risks to crop productivity and world food security is drought stress. This review aims to examine the physiological mechanisms of drought tolerance in tomatoes. ROS produced by drought-induced oxidative stress harm chloroplasts and other cellular components, further reducing photosynthetic efficiency. Many adaptation techniques have been developed by plants to mitigate these consequences. Tolerance is also strengthened by structural modifications like rearranged leaves and changed root architecture. Developing crop types resistant to drought and guaranteeing sustainability requires an understanding of these intricate relationships and adaptive techniques.
