植物逆境胁迫相关蛋白激酶的研究进展

干旱、高盐、高温和低温等非生物胁迫及各种病虫害等生物胁迫严重影响植物的生长发育和作物产量.蛋白激酶主要通过激活不同的磷酸化途径介导外界环境信号的感知和传递,调控下游抗逆基因的转录表达,启动相应的生理生化等适应性反应来降低或消除危害.该文对近年来国内外有关与非生物胁迫和生物胁迫信号传导相关的受体蛋白激酶、促分裂原活化蛋白激酶、钙依赖而钙调素不依赖的蛋白激酶、蔗糖不发酵相关蛋白激酶和其它胁迫相关的植物蛋白激酶的研究进展进行综述,探索蛋白激酶介导的不同磷酸化途径应对逆境胁迫的信号传递网络,为进一步了解植物逆境分子应答机制提供依据.

Research Progress on Stress-related Protein Kinases in Plants

Abiotic and biotic stresses,including drought,high-salinity,high-and low-temperature,and many diseases seriously affect plant growth and crop yield.Protein kinases mediate the perceiving and transducing of external environment signals via activating diverse phosphorylation pathways,regulate the expression of downstream resistant genes,and trigger multiple physiological and biochemical reactions to minimize and eliminate hazards.Based on previous studies,we reviewed the progress in the researches on plant protein kinases,such as receptor-like kinase(RLK),mitogen-activated protein kinase(MAPK),calcium-dependent and calmodulin-independent protein kinase(CDPK) and sucrose non-fermenting-1-related protein kinase(SnRK),which participate in abiotic and biotic stress signal pathways in recent years and explored signal transduction networks of diverse phosphorylation pathways in the responsive reactions.Moreover,some emphases in the future study were put forward.This paper provides the basis for deep understanding the molecular mechanism of plant resistance.
