Abstract:

Drought stress is one of the major abiotic stresses and seriously hinders the production of crops. The increased level of ROS under drought stress causes oxidative stress,destroys lipid,nucleic acid and protein,and finally leads to cell damaged and even death. Therefore,it is critical to maintain the physiological level of ROS for aerobic organisms,through the coordinated control of enzymatic and non-enzymatic antioxidants. This article summarizes the production,scavenging and signal transduction of ROS under drought stress,which may provide a reference for studies on plant response to drought stress.

Key words: drought stress, reactive oxygen species, oxidative stress, enzymatic antioxidants
