摘　　要：蛋白质的可逆磷酸化是细胞信号识别与转导的重要环节。促分裂原活化蛋白激酶(mitogen-activatedprotein kinases,MAPKs)是一类丝氨酸/苏氨酸(Ser/Thr)蛋白激酶,主要催化蛋白质的磷酸化过程。植物中存在大量的MAPKs,它们在多种信号传递过程中起重要作用。笔者着重介绍MAPKs在植物逆境信号识别与转导中的作用。Reversible phosphorylation of protein is an important link in cellular signal transduction and recognition.Mitogen-activated protein kinases（MAPKs） are Serine/Threonine protein kinases,and mainly catalytic phosphorylation of protein.A large number of MAPK family members have been found in plants.They play an important role in the many kinds of stress signals transduction.This review focuses on the function of MAPK cascades in signal transduction during the process of plant response to stress.

关 键 词：蛋白激酶 逆境胁迫 信号转导
