Figure 3.—

Comparison of the basal F-actin of middle stage egg chambers stained with phalloidin. (A) Basal F-actin of wild-type egg chamber is organized in parallel bundles that are oriented perpendicularly to the A–P axis. (B) Basal F-actin of pak⁶/pak¹¹ egg chamber displaying disorganized F-actin bundles that have no specific orientation with respect to the A–P axis. (C) Basal F-actin of rhoGEF2⁰⁴²⁹¹/+; pak⁶/pak¹¹ egg chamber showing that suppressors of the pak rounded egg chamber phenotype suppress the basal F-actin disorganization. Bar: 25 μm.
