Characterization of a G-protein-regulated outward K+ current in mesophyll cells of Vicia faba L

Whole-cell voltage-dependent currents in isolated mesophyll protoplasts of Vicia faba were investigated by patch-clamp techniques. With 104 millimole K+ in the cytosol and 13 millimole K+ in the external solution, depolarization of the plasma membrane from -47 mV to potentials between -15 and +85 mV...
