Fig. 2. Dorsal patterning defects in sec5^E13. Stage 10 egg chambers with wild-type (A) or sec5^E13 (B-D) germline clones. Some mutants lack phalloidin (red) between nuclei (blue) and have aggregated ring canals (C, arrow). However, many sec5^E13 germlines (D) more closely resemble wild type. Wild-type eggs (E) have two stereotypically spaced appendages on the dorsal side. All eggs laid by sec5^E13 germline mothers display fused or closely spaced dorsal appendages (F). Scale bars: 20µm.
