摘　　要：植物的三种蛋白激酶MAPKKK、MAPKK和MAPK组成了丝裂原活化蛋白激酶(MAPK)级联信号系统,可快速放大胞外刺激并将其转化为胞内响应。在此过程中,丝裂原活化蛋白激酶激酶(MAPKK)是MAPK通路的中间环节,在信号放大和传递过程中至关重要。大量研究表明, MAPKK在植物生长发育及胁迫响应等过程中发挥重要作用。本文从植物MAPKK的结构特征、细胞定位、生长发育调控、生物及非生物胁迫响应等方面进行了综述,并展望了未来的研究方向,期望对相关研究提供借鉴。The plant mitogen-activated protein kinase(MAPK) cascades are composed of three protein kinases(MAPKKK, MAPKK and MAPK), which can quickly magnify the extracellular stimulation and convert it as intracellular response. In this relationship, mitogen-activated protein kinase kinase(MAPKK) is the intermediate link of MAPK cascades, which is vital in signal amplification and transmission. A large number of reports have shown that MAPKK plays a crucial role in plant growth and development, as well as response to the biotic and abiotic stresses. In this paper, the plant MAPKK is reviewed and discussed in the structural characteristics, cell localization, regulation of growth and development, response to biotic and abiotic stresses, and the ideas for the further study is prospected, which is expected to provide reference for related research.
