植物K^+通道AKT1的研究进展

Research Advance of K^+ Channel AKT1 in Plants

钾(K)是植物生长发育必需的大量营养元素之一,主要通过根细胞的K^+通道及转运蛋白介导吸收。AKT1是Shaker型K^+通道家族的重要成员,在植物根吸收K^+和体内跨膜转运中发挥重要作用。该文综述了植物AKT1的分子结构、组织特异性表达、调控机制及生物学功能等方面的研究进展,并对该通道今后的研究方向进行了展望。

Potassium（K） is an essential macronutrient for plant growth and development. K~＋ uptake was mainly mediated by K~＋ channels and transporters in root cells. Arabidopsis K~＋ transporter 1（AKT1） is one of the important members of the Shaker type K~＋ channel families and plays crucial roles in root K~＋ uptake and transmembrane transport of plants. Here, we summarize the latest research advances for the K~＋ channel AKT1, mainly its molecular structure, tissue-specific expression, regulation mechanisms, and biological function. We propose research hotspots and directions for research into the AKT1 channel.
