植物MAP激酶级联途径研究进展

MAP激酶(促分裂原活化蛋白激酶)级联途径可以将不同的细胞膜感受器与细胞应答联系起来,响应各种生物以及非生物胁迫,在植物激素信号以及细胞分裂和发育过程中发挥着重要的作用.为有效地传递各种特异信号,MAP激酶级联相互交叉形成复杂的信号传递网络.近年来,随着功能获得型突变体、功能缺失型突变体的获得以及其它一些新技术的应用,进一步阐明了MAP激酶级联途径在信号传导过程中的功能和作用.本文主要对植物MAPK级联途径在信号传导过程中交叉串通以及复杂性的最新研究结果进行综述.

Research Advances about MAPK Pathways in Plants

Mitogen-activated protein kinase(MAPK) pathways play a central role in transfer information from diverse receptors/sensors to a wide range of cellular responses in plants.Signaling through MAP kinase cascade can lead to cellular responses including cell division,development,hormone physiology,as well as response to a broad variety of biotic and abiotic stresses.MAP kinases are organized into a complex network for efficient transmission of specific stimuli.In recent years,the loss-of-function mutant,the gain-of-function mutant and other additional tools were used to investigate the plant MAPK cascades.The functions of the individual MAPK cascade in particular signal transduction pathway were described.This review briefly summaries the recent research results about the cross-talk and complexity of MAP kinase cascades in plant.
