Fig. 7. RNAi phenotypes of cdl-1 and core histone genes. (A,D) The predominant RNAi phenotypes for cdl-1 (A) and the histone H4 gene (D). Embryos arrest with around 50 cells in both cases. (B,C,E,F) Embryos showing later embryonic RNAi phenotypes, which are similar to those of the cdl-1 mutants. (B,C) cdl-1, (E,F) the histone H2B gene. Arrows indicate cell corpses. Arrowheads indicate the anterior tip of the pharynx. Scale bar, 10 µm.
