摘要: 多种有机和无机离子作为重要的营养物质、渗透物质、辅酶和信号分子, 参与植物生殖、生长发育和逆境反应等多种生物学过程。离子通道是离子跨质膜和内膜运动的重要渠道和动态调控因子, 直接影响和调控细胞内离子浓度及亚细胞分布的动态变化。目前, 植物尤其是模式植物拟南芥(Arabidopsis thaliana)的多个离子通道家族被先后鉴定出来, 其中部分离子通道蛋白定位在细胞质膜上, 其基本生物学功能, 诸如蛋白结构、离子选择性和通透性、门控特点、活性调控机理以及不同离子通道之间的协同关系等均取得重要进展。该文概要介绍近年来植物细胞质膜离子通道方面的研究进展。

Abstract: Multiple ions, including cations and anions, are involved in growth, development, reproduction and stress responses as essential nutrients, osmotic components, cofactors of proteins and signaling molecules in plants. Ion channels localized in the plasma membrane and endomembrane of plant cells are essential tunnels and dynamic regulators of ion flux across biological membranes and are involved in the direct regulation of ion homeostasis in plant cells. A large number of ion channels have been identified in diverse plant species, especially in the model plant Arabidopsis, in recent years. Many ion channels are localized in the plasma membrane, and their protein structure, ion selectivity and permeability, gating patterns, activity-regulating mechanisms and the functional coordinating mechanisms between different ion channels have been analyzed. In this review, we summarize the research progress on the plasma membrane ion channels of plant cells and discuss the outstanding questions.
