As a ubiquitous secondary messenger in plant signaling systems, calcium ions (Ca) play essential roles in plant growth and development. Within the cellular signaling network, the accurate decoding of diverse Ca signal is a fundamental molecular event. Calcium-dependent protein kinases (CDPKs), identified commonly in plants, are a kind of vital regulatory protein deciphering calcium signals triggered by various developmental and environmental stimuli. This review chiefly introduces Ca distribution in plant cells, the classification of CDPKs (AtCDPKs), the identification of the Ca-AtCDPK signal transduction mechanism and AtCDPKs’ functions involved in plant growth regulation and abiotic stress responses. The review presents a comprehensive overview of AtCDPKs and may contribute to the research of CDPKs in other plants.
钙离子（Ca）作为植物信号系统中普遍存在的二级信使，在植物生长和发育中发挥着重要作用。在细胞信号网络中，对各种 Ca 信号的准确解码是一个基本的分子事件。钙依赖蛋白激酶（CDPKs）是植物中普遍存在的一种重要调节蛋白，可对各种发育和环境刺激引发的 Ca 信号进行解码。本综述主要介绍了植物细胞内 Ca 的分布、CDPKs（AtCDPKs）的分类、Ca-AtCDPK 信号转导机制的鉴定以及 AtCDPKs 参与植物生长调控和非生物胁迫响应的功能。该综述全面概述了 AtCDPKs，可能有助于其他植物中 CDPKs 的研究。
