Abstract
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.
