Y. Nishizaki, VANADATE AND DICYCLOHEXYLCARBODIIMIDE INHIBIT THE BLUE LIGHT-INDUCED DEPOLARIZATION OF THE MEMBRANE IN PULVINAR MOTOR CELLS OF PHASEOLUS, Plant and Cell Physiology, 35(5), 1994, pp. 841-844
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.
