Abstract
Transient depolarization of cell membranes precedes induction by a pul se of blue light (BL) of pulvinar movement in Phaseolus vulgaris. The depolarization may involve the plasma membrane H+-ATPase since vanadat e and dicyclohexylcarbodiimide decreased or almost completely inhibite d depolarization. BL may inactivate the enzyme, thereby decreasing the turgor pressure in motor cells.
