摘要

钾(K)作为植物所需的3种大量元素之一，参与体内诸多的生理和生化过程，对于植物的生长和发育极其重要。目前，国内外学者对植物吸收、运输和利用K⁺的研究已有一定深度，尤其以模式植物拟南芥(Arabidopsis thaliana (L.) Heynh.)为研究对象。其中，与K⁺吸收、转运相关的离子通道和转运蛋白一直都是研究热点。本文综合近年来国内外相关研究进展，主要阐述K⁺通道和转运蛋白，K⁺的吸收和运输，类钙调磷酸酶(Calcineurin B-Like，CBL)-CBL相互作用蛋白激酶(CBL-Interacting protein kinase，CIPK)信号途径，参与该信号转导的一些小信号分子，对K⁺研究方面存在的问题进行了总结，并对未来的研究方向进行了展望。

Abstract：

As one of the three macronutrients required by plants, potassium (K) participates in many physiological and biochemical processes in the body and is extremely important for plant growth and development. Research has been carried out on K⁺ absorption, transportation, and utilization by plants, especially the model plant Arabidopsis thaliana, with a particular focus on ion channels and transporters related to K⁺ absorption and transport. This article summarizes current research progress, especially that related to K⁺ channels and transporters, K⁺ absorption and transport, calcineurin B-like (CBL)-CBL-interacting protein kinase (CIPK) signaling pathway, and small signal molecules involved in signal transduction. This article also summarizes existing problems in K⁺ research and discusses future research directions.

Key words： Arabidopsis thaliana K⁺ channel Transporter CBL-CIPK Signal molecule
