Movie 4

Rho-GEF2 photo-activation results in apical or basal cell constriction
Time-lapse movies showing apical (left) and basal (right) views of wing discs expressing RhoGEF2-CRY2 and CIBN::pmGFP before and during illumination with blue light at the apical (left) or basal (right) region of cells. Time after onset of a two-minutes illumination is indicated. Cell membranes are visualized by CIBN-pmGFP. Scale bars: 10 μm.
