Figure 2From: Polarization of the endomembrane system is an early event in fucoid zygote developmentEndomembrane accumulation marks the rhizoid pole. Vital staining of a field of 6 zygotes with FM4-64 during photopolarization (a, 8 h AF) and following germination (b, 20 h AF). Each zygote germinated at the position previously marked by brightest FM4-64, except for the cell indicated by an asterisk, which had uniform labeling at 6 h and did not germinate. Arrow indicates direction of orienting light vector and scale bar = 100 μm.Back to article page
