植物蛋白磷酸酶2C在非生物胁迫信号通路中的调控作用

摘要

植物在非生物胁迫下会产生一系列的形态、生理生化和分子水平上的适应性变化，尤其是非生物胁迫会引起植物体内的蛋白磷酸酶2C（PP2C）基因表达的改变，从而诱导植物合成相关的蛋白以适应胁迫。植物中有不同类型的PP2C亚群，各种PP2C亚群能够通过不同的信号途径参与胁迫应答，因此在植物响应非生物胁迫的过程中发挥重要作用。综述了植物PP2C在非生物胁迫信号通路中的作用机制。%Abiotic stress could cause a series of changes to plants in morphological, physiological, biochemical and molecular level. Especially the abiotic stresses would lead protein phosphorylase PP2C related gene expression change. At the same time, the proteins related biosynthesis induced by the abiotic stresses would improve plants resistance. However, the different PP2C through the different signaling pathways involved in abiotic stress. This article introduced the regulative mechanisms of PP2C mediated the abiotic stress signal pathways.
