Salt stress research focuses on understanding how plants respond to and cope with high salt levels in soil or water. This type of stress can inhibit plant growth and development, reduce crop yield, and ultimately impact food security. Researchers study the mechanisms that plants use to tolerate salt stress, such as ion transport, osmotic adjustment, and antioxidant defense systems. By understanding these processes, scientists aim to develop salt-tolerant crop varieties that can thrive in saline environments and contribute to sustainable agriculture.
