摘要: AKT1 is an important K+ channel that mediates K+ uptake in Arabidopsis root. Here, we demonstrated that AKT1 plays an essential role in Arabidopsis response to low K+ stress. AKT1 can perceive external K+ concentration and subsequently regulate primary root growth by modulating PIN1 degradation and auxin redistribution.
