title: Ion Efflux from Pulvinar Cells during Slow Downward Movement of the Petiole of Mimosa pudica L. Induced by Photostimulation.
abstract: Change of extracellular ion concentration in the main pulvinus of Mimosa pudica L. during a slow downward movement induced by white light (0.24 mW cm(-2)) was investigated using K(+)- and Cl(-)-selective electrodes and a pH electrode. The photostimulation induced a transient and concurrent efflux of K(+) and Cl(-) from the motor cells and acidification of extracellular pH in the main pulvinus.
