摘要:

钾是植物必不可缺的大量元素,作为细胞内的主要溶质,参与植物的生长发育过程。植物通过钾通道和钾转运体两种方式吸收钾营养。钾转运体包括4个家族,其中KUP/HAK/KT家族成员最多,且研究最为深入。其成员是广泛存在于植物细胞质膜和液泡膜上的一种跨膜蛋白,多具有高亲和性钾吸收功能的转运体。KUP/HAK/KT转运体不仅在植物对K+的吸收与转运过程中发挥作用,也参与调节植物的生长发育。综述了植物KUP/HAK/KT家族的分类、组织定位、功能和表达调控等方面的研究进展,以期为研究植物的钾营养吸收机制提供理论参考。

Abstract:

Potassium is an essential mineral element in cytolist for plant growth and development. Plants absorb potassium through potassium channels or transporters. There are 4 potassium transporters families, among which KUP/HAK/KT families have the largest family members and received most thorough studies. Its members are kinds of transmembrane protein, which exist on plant plasma or tonoplast and have high affinity with K+. KUP/HAK/KT transporter not only play roles in plant absorbing and transporting K+, but also take part in adjusting plant growth and development. This paper expounded the research progress on classification, tissue localization, physiological function and expression regulation of the KUP/HAK/KT family, so as to provide theoretical references for studying the mechanism of plant potassium absorption.

Key words: potassium transporter, KUP/HAK/KT, classification, function, expression regulation
