Additional RNAi mutant phenotypes. Stage 13 (A and B) or 15/16 (C-I) embryos were stained with BP102 (A, C, E, and G) or 22C10 (B, D, F, H, and I) mAb after injection of the dsRNA indicated at top of each image. Ventral (A-C, E, and G) and lateral (D, F, H, and I) views of embryos are shown. The arrow in C indicates abnormal commissures.
