摘　　要：钙依赖蛋白激酶(CDPKs)是生长发育信号和逆境信号诱发的钙信号的重要信号传递体,在调控植物信号转导途径中下游基因的表达、生化代谢、离子和水分跨膜运输等生物学过程中具有重要作用。本研究对植物种属CDPK的结构特点、CDPK在植株体内的分布特征、CDPK生理生化特性及生化反应调控特性、CDPK在信号转导中的作用,以及CDPK在植株体内的生物学功能进行了概述。旨在为今后牧草作物CDPK的鉴定及其介导的信号转导机制的研究提供参考依据。An important component of the Ca^2＋ signal cascade induced by signals of plant growth and development, and biotic or abiotic stresses, is the calcium-dependent protein kinases （CDPKs） which play a vital role in biological processes, such as regulation of the expression of downstream genes, modification of biochemical metabolisms, controlling the transportation of ions and water. In this paper, the structure characterization,distribution property, physiological and biological properties, role in signal transduction, and the biological function in plants of the CDPKs are summarized, to provide a theoretical guidance for identification of CDPKsand exploration of the signal transduction mechanisms mediated by CDPKs in forage crops.
