Movie 4

Cortical F-actin in live embryos: partial rescue of F-actin dynamics in aura mutants by phalloidin treatment. Left: cortical F-actin in aura mutants, as in Movie 1 (right) and corresponding to still data in Fig. 6B. F-actin dynamics defects characteristic or aura mutants are partially restored, as manifested by local cortical contractions and expansions. Representative movie of 3 trials. In both movies, F-actin is detected by the Life Act transgene, with images at 200x magnification, corresponding to scale bar in Fig. 6.
