Abstract:

As one of 3 essential nutrients for plant growth and development,potassium(K)plays an crucial role in regulating enzyme activity,membrane potential,cell homeostasis,and protein stable synthesis. K+ uptake and transport in plant is via potassium channels and transporters. In recent years,different types of potassium channels have been isolated. The earliest discovered and most studied potassium channel is the Shaker potassium channel. This paper introduces the potassium channel in plant in aspects of its classification,the structural characteristics of the Shaker potassium channel,the effects of AKT1 on plant growth and development,the function of AKT1 under abiotic stress and biotic stress,and 2 internal regulation mechanisms of potassium channel AKT1 by CBL/CIPK phosphorylation and heteromerization. The paper also prospects the future issues in studying the potassium channel AKT1.

Key words: potassium ion, potassium ion channel, AKT1, regulation
