摘要 干旱是严重限制作物生长及产量的环境因子之一。经过长期的进化,植物形成了一套响应干旱胁迫的信号转导机制,包括对干旱胁迫信号的感知,第二信使的产生,信号转导和信号网络的形成。信号转导的结果是导致相关基因的表达和蛋白的合成,进而引起植物体渗透调节及抗氧化系统的改变,最终使植物适应干旱逆境或增强植物抗旱能力。干旱胁迫通常会促进ROS的积累及其他次级信号分子的产生。MAPK级联途径是真核生物信号转导最为保守的途径,在植物的生长发育及各种胁迫信号的传导中均起着较重要的作用。综述干旱胁迫信号及ROS→MAPK和ROS→Ca2+介导的信号途径,以及信号转导途径的调控机制。 Drought is a major environmental factor among many factors limiting productivity and growing of plants.Plants have developed signal transduction mechanism from long-term drought stress,including signal acceptation,the formation of second messenger,signal transduction and signal networks.The result of the signal transduction is related gene expression and protein synthesis.Thereby causing the changes of plant osmotic adjustment and antioxidant defense system,the plants adaptions to environment will eventually increase and drought stress resistance of plants also will be improved.Drought stress will usually promote the accumulation of ROS,and a number of secondary signaling molecules will generate.MAPK cascade signal pathway is one of the most conservative approaches in eukaryotes,and plays a very important role in plant's growth,development and various stress signal transduction.This paper outlines the drought signals,both ROS→ MAPK and ROS→Ca2+mediated drought signal pathways,and regulatory mechanism of signal transduction pathways.
