The effect of red and far-red light on proton secretion from mesophyll-cell protoplasts of Vicia faba L.
The influence of red and far-red irradiation on the transport of H(+) and (86)Rb(+) through the plasmalemma was studied using parenchymal protoplasts isolated from Vicia faba leaves. The results indicate that red light stimulates H(+) secretion and the uptake of (86)Rb(+). Moreover, it has been demonstrated that far-red irradiation acts antagonistically with respect to red light in both these processes.
