Abstract: Mitogen-activated protein kinase (MAPK) is a highly conserved protein kinase, which widely exists in eukaryotes. The MAPK cascade pathway is an important and highly conserved cellular signal transduction pathway, and it mainly includes three kinds of protein kinases, MAPKK, MAPKK and MAPK, which are activated by phosphorylation in turn. The MAPK cascade pathway is involved in plant growth and development, hormone regulation, biological stress and abiotic stress response. This paper presented the structure character and the response to abiotic stress of MAPK cascade members of plant. It would be helpful for understanding the function and regulation of MAPK cascade members of plant in response to abiotic stress.

摘要： 促分裂原活化蛋白激酶（mitogen-activated protein kinase, MAPK）是一种高度保守的蛋白激酶，广泛存在于真核生物中。MAPK级联途径是一种重要的高度保守的细胞信号转导途径，主要包括MAPKKK、MAPKK和MAPK三种蛋白激酶，通过磷酸化顺序被激活。MAPK级联途径参与了植物生长发育、激素调节、生物胁迫以及非生物胁迫的应答响应。从植物MAPK级联途径成员的分类、结构特征及对非生物胁迫的响应等方面进行了综述，将为系统的理解植物MAPK级联途径及其在非生物逆境胁迫下的表达调控等提供参考。
