摘　　要：植物钙通道蛋白几乎在植物生长发育的所有阶段都是必需的,它们参与细胞内钙离子浓度的调控,在植物细胞内钙离子的跨膜转运过程中起着极其重要的作用;它们同时调控植物细胞和组织的极性生长,参与植物应对一系列不同逆境胁迫因素的适应性反应,在植物抗逆方面同样起着极其重要的作用。本文对近年来国内外有关不同钙通道蛋白的性质及其在植物抗冷性和抗盐性中的作用研究进展进行综述,为在生理水平和分子水平上深入阐明植物钙通道蛋白参与植物抗逆性的机理提供信息资料。Plant calcium channel proteins are needed at almost all stages of plant growth and development.They participate in the regulation of intracellular Ca2＋ concentration,and play an important role in the trans-membrane transport of Ca2＋ in plant cells.Meanwhile,plant calcium channel proteins not only regulate the polar growth of plant cells and tissues,and participate in plant adaptations to a serious of various stress factors,but also play an identically important role in plant stress resistance.In this paper,the characteristics of calcium channel proteins and their roles in plant salt and cold resistance are mainly reviewed,so as to provide theoretical basis for the elucidation of the mechanism of calcium channel proteins involvement into plant stress resistance at both physiological and molecular levels.
