Our knowledge of plant ion channels was significantly enhanced by the first application of the patch-clamp technique to isolated guard cell protoplasts over 35 years ago. Since then, research has demonstrated the importance of ion channels in the control of gas exchange in guard cells, their role in nutrient uptake in roots, and the participation of calcium-permeable cation channels in the regulation of cell signaling affected by the intracellular concentrations of this second messenger. In recent years, through the employment of reverse genetics, mutant proteins, and heterologous expression systems, research on ion channels has identified mechanisms that modify their activity through protein-protein interactions or that result in activation and/or deactivation of ion channels through posttranslational modifications. Additional and confirmatory information on ion channel functioning has been derived from the crystallization and molecular modeling of plant proteins that, together with functional analyses, have helped to increase our knowledge on the functioning of these important membrane proteins that may eventually help to improve crop yield. Here, an update on the advances obtained in plant ion channel function during the last few years is presented. Expected final online publication date for the Annual Review of Plant Biology, Volume 72 is May 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

植物离子通道生理学新进展

35 年前,膜片钳技术首次应用于分离的保卫细胞原生质体,显着增强了我们对植物离子通道的了解。从那时起,研究证明了离子通道在保卫细胞中控制气体交换中的重要性,它们在根部养分吸收中的作用,以及钙渗透性阳离子通道参与调节受细胞内浓度影响的细胞信号传导。这个第二使者。近年来,通过使用反向遗传学、突变蛋白和异源表达系统,对离子通道的研究已经确定了通过蛋白质 - 蛋白质相互作用改变其活性或通过翻译后修饰导致离子通道激活和/或失活的机制. 关于离子通道功能的额外和确证信息来自植物蛋白的结晶和分子建模,这些信息与功能分析一起有助于增加我们对这些可能最终有助于提高作物产量的重要膜蛋白功能的了解。在这里,介绍了过去几年在植物离子通道功能方面取得的进展的最新情况。《植物生物学年度评论》第 72 卷的预计最终在线出版日期是 2021 年 5 月。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计值。有助于增加我们对这些可能最终有助于提高作物产量的重要膜蛋白功能的了解。在这里,介绍了过去几年在植物离子通道功能方面取得的进展的最新情况。《植物生物学年度评论》第 72 卷的预计最终在线出版日期是 2021 年 5 月。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计值。有助于增加我们对这些可能最终有助于提高作物产量的重要膜蛋白功能的了解。在这里,介绍了过去几年在植物离子通道功能方面取得的进展的最新情况。《植物生物学年度评论》第 72 卷的预计最终在线出版日期是 2021 年 5 月。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计值。
