Calcium signals play an important role in many aspects of plant growth and development, including plant response to biotic and abiotic stress. The stimulus characteristic intracellular Ca2+ signals are generated in plant cells by a variety of stimuli, including changes in environmental conditions, interaction with microbes and growth and development processes. Cytoplasmatic calcium brings about responses by interacting with target proteins, like calcium-dependent kinases. In plant there are at least five classes of protein kinases (CDPK, CRK, CCaMK, CaMK and SnRK3), which activity is regulated by calcium ions. In this article the structure, regulation and function of calcium stimulated protein kinases are briefly reviewed.
钙信号在植物生长发育的许多方面发挥着重要作用，包括植物对生物和非生物胁迫的响应。植物细胞中由多种刺激产生具有刺激特征的细胞内Ca2+信号，这些刺激包括环境条件的变化、与微生物的相互作用以及生长发育过程。细胞质钙通过与靶蛋白（如钙依赖性激酶）相互作用引发反应。在植物中至少有五类蛋白激酶（CDPK、CRK、CCaMK、CaMK和SnRK3），其活性受钙离子调节。本文简要综述了钙刺激蛋白激酶的结构、调节和功能。
