Figure 5From: Polarization of the endomembrane system is an early event in fucoid zygote developmentEndocytosis is inhibited by actin disruption. Zygotes 6 h AF were treated for 30 min with DMSO (a) or 30 nM Lat B (b) and then labeled with FM4-64 for 30 min in the presence of drug. Diffuse cortical fluorescence in (b) is primarily due to out-of-focus labeling of plasma membrane. Bar = 50 μm.Back to article page
