Molecular basis of plant-specific acid activation of K+ uptake channels

During stomatal opening potassium uptake into guard cells and K+ channel activation is tightly coupled to proton extrusion. The pH sensor of the K+ uptake channel in these motor cells has, however, not yet been identified. Electrophysiological investigations on the voltage-gated, inward rectifying K...
