membrane potential of Arabidopsis thaliana guard cells; depolarizations induced by apoplastic acidification

The apoplastic pH of guard cells probably acidifies in response to light, since light induces proton extrusion by both guard cells and epidermal leaf cells. From the data presented here, it is concluded that these apoplastic pH changes will affect K+ fluxes in guard cells of Arabidopsis thaliana (L....
