摘要:

干旱胁迫是主要的非生物胁迫之一,严重阻碍了作物的生产。干旱胁迫导致ROS水平升高,过量的ROS会引起氧化胁迫,严重破坏脂质,核酸和蛋白质,导致严重的细胞伤害,甚至死亡。因此,维持ROS的生理水平对于需氧生物至关重要,它依赖于酶促抗氧化剂和非酶抗氧化剂等途径的协调作用。综述了干旱胁迫下ROS的产生、清除及信号转导的研究进展,旨为植物对干旱胁迫响应的研究提供参考。

关键词: 干旱胁迫, ROS, 氧化胁迫, 酶促抗氧化剂

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
