摘　要：

脱落酸(ABA)是植物体内一种重要的激素分子, 在调节植物生长发育和对环境适应的过程中发挥重要的信号作用。 促分裂原活化蛋白激酶(MAPK)是一种广泛存在于真核生物中的信号转导途径, 由环境胁迫、细胞因子、植物激素、生长因子等诱导, 是植物细胞信号转导过程中的主要级联途径之一。已知许多蛋白激酶和蛋白磷酸酶参与了ABA信号途径, MAPKs作为ABA信号转导的下游组分发挥着重要的调节作用。本文就MAPK级联参与ABA信号转导途径的相关研究进 展进行叙述, 以便对MAPKs和ABA信号之间的交互作用(cross-talk)机制有更深入了解。

Abstract:

Abscisic acid (ABA), one of the most important hormones in plants, plays a very important role in regulating the process of plant growth and development and environment adaptation. Mitogen-activated protein kinase (MAPK) cascade, a widely present in eukaryotic signal transduction pathways, is induced by stress, cytokines, plant hormones and growth factors, and is also one of the key cascades in the process of signal transduction in plant cells. It is well known that many protein kinases and protein phosphatases are involved in ABA signal pathway. MAPKs, identified as downstream components of ABA signal, play a regulatory role. This paper reviewed the recent progress in MAPKs involved in ABA signal transduction pathways in order to provide insights into the cross-talk mechanism between MAPKs and ABA signal in plants.
