Mechano-avoidance movement of chloroplasts in the dark. A, A protonemal cell was continuously stimulated from both sides of the cell with the flank of bent microcapillaries. The avoidance movement of chloroplasts can be seen in a video supplement at www.plantphysiol.org. B, Time course of avoidance movement of individual chloroplast induced by short-term (1 min) mechano-stimulation from one side (vertically) with the flank of a capillary. Bar, 20 μm.
