| 摘 要： | Ca^2＋信号是植物应答各种逆境胁迫响应的一个重要组分，它在植物抗病、抗虫及适应非生物胁迫反应中起着重要的作用。Ca^2＋信号作为第二信使在激素信号转导尤其是ABA信号转导过程中发挥着重要作用。研究表明，当植物受到如干旱、低温、盐害等环境胁迫时，细胞迅速积累ABA，胞内钙离子浓度瞬间升高，然后钙离子浓度呈现忽高忽低的震荡现象。在植物细胞中发现Ca^2＋／CDPK、Ca^2＋／CaM和Ca^2＋／CBL三类钙信号系统，它们与逆境胁迫信号转导密切相关。本文通过综述植物在逆境条件下，ABA与钙信号的产生、转导及产生适应性和抗性等方面，介绍了ABA与钙信号之间的相互调节机制。

| Abstract: | The Ca2+ signal is a very important component in plants responsive to environmental stresses. It plays a critical role in plants to resistantance diseases,insects defense and acclimation non-biological stresses. The Ca2+ signal takes the influential role as a second messenger in hormone signal transduction,particularly in the ABA signal transduction process. When encourtered with abiotic stresses,such as cold,drought,and salt,plants rapidly accumulated ABA and elevated the calcium ion concentration instanta... |
