Calcium-dependent protein kinases (CDPKs) constitute a large multigene family in various plant species. CDPKs have been shown to have important roles in various physiological processes, including plant growth and development and abiotic and biotic stress responses in plants. Functional analysis using gain-of-function and loss-of-function mutants has revealed the biological function of CDPKs in planta. Several CDPKs have been shown to be essential factors in abiotic stress tolerance, positively or negatively regulating stress tolerance by modulating ABA signaling and reducing the accumulation of reactive oxygen species (ROS). This review summarizes recent results describing the biological function of CDPKs that are involved in abiotic stress tolerance.
钙依赖型蛋白激酶(CDPKs)在各种植物物种中构成一个大型多基因家族。已经表明,CDPKs 在各种生理过程中具有重要作用,包括植物生长和发育以及植物的非生物和生物胁迫反应。使用功能获得和功能丧失突变体进行的功能分析揭示了 CDPKs 在植物体内的生物学功能。已经表明,一些 CDPKs 是非生物胁迫耐受性的必需因素,通过调节 ABA 信号和减少活性氧(ROS)的积累,正或负地调节胁迫耐受性。本综述总结了描述参与非生物胁迫耐受性的 CDPKs 的生物学功能的最新结果。
