摘要
环核苷酸门控离子通道(CNGCs)是植物体内重要的非选择性的四聚体阳离子通道,参与植物细胞离子选择通透性、生长发育、生物和非生物胁迫响应等多种生物学功能的调控。本文简要介绍了植物中CNGCs的分类和定位,并阐述了CNGCs的结构和其异四聚体组装的最新进展,总结了近年来CNGCs在植物生长发育、对盐、干旱、冷、热和重金属等非生物胁迫的耐性及抗病反应等生物学功能方面的研究,讨论了CNGCs关于被cNMP激活调控的争议以及磷酸化和CaM调控模式的最新研究进展,为深度发掘其功能奠定基础。
Cyclic nucleotide-gated ion channels(CNGCs) are important non-selective cation channels in plants,which are involved in the regulation of various biological functions such as plant cell ion selective permeability,growth and development, responses to biotic and abiotic stresses. The present paper reviewed the latest findings on the classification, positioning, and structure of CNGCs as well as the assembly of their heterotetramers in plants, and summarized the latest progress in the biological function of CNGCs in plant growth and development, responses to abiotic stresses including salt, drought, cold, heat, heavy metals and disease resistance. The controversy on CNGCs activation by cNMP and their regulation by phosphorylation and CaM were also discussed in this paper. This article provided a basis for an indepth exploration of its functions.
