Phallusia: Actin dynamics in the zygote at entry into mitosis

Organism : Ascidian
Species : Phallusia mammillata
Description : Z-projection of a confocal timelapse showing the cortical actin. LifeAct::Venus protein was injected into unfertilized oocytes that were subsequently fertilized. The animal pole is upNote the deformation of the zygote and the transient loss of vegetal cortical actin when the female PN reaches the sperm aster (circa 14 min time point). Scale bar is 40 µm.
