摘要: 钙信号是一种重要的第二信使,在动植物生长发育和信号转导中具有重要的调节作用。为了深入了解其参与植物低温响应的作用机理,笔者归纳了钙离子转运系统和相关钙离子感受器的结构和功能,并从生理变化和基因表达2 个方面分析了钙信号参与植物低温响应的研究进展;总结了Ca2+转运系统、CaM、CMLs、CBLs和CDPKs中参与植物低温响应的基因,并简要分析了其作用机制。分析表明钙信号能通过多条途径增强植物的低温抗性,在农业生产中具有重要的现实意义。

Abstract: Calcium signal is an important second messenger with diverse functions in developmental regulation and signal transduction in both animals and plants. In order to further study the molecular details of the connection between calcium signaling molecules and low temperature responses of plants, the authors summed up the structure and function of the calcium transport system and calcium ion receptors, and analyzed some recent research progresses of the calcium signal participating in the response of plants to low temperature from the physiological changes and gene expression. In addition, the calcium transport system, CaM, CMLs, CBLs and CDPKs genes involved in low temperature response of plants were summarized, and their mechanism of action was briefly analyzed. Available evidences show that calcium signal can improve the plant tolerance to cold through different regulatory pathways and this may have important implications in agriculture.
