Fusicoccin (FC) has long been known to promote K+ uptake in higher plant cells, including stomatal guard cells, yet the precise mechanism behind this enhancement remains uncertain. Membrane hyperpolarization, thought to arise from primary H+ pumping stimulated in FC, could help drive K+ uptake, but the extent to which FC stimulates influx and uptake frequently exceeds any reasonable estimates from Constant Field Theory based on changes in the free-running membrane potential (V m) alone… CONTINUE READING
