Figure 4


Fig. 4. Ena is essential for morphogenesis. Cuticles. Wild-type (A,J) and representative ena mutant (C,H,I) or FP4mito-expressing (B,D-G,K) embryos illustrating phenotypic classes. (J,K) Close-ups of A,B. Arrowheads, wild type (A,J) or defective dorsal midline (B,D,G,K). Arrows in A,C,D, wild type (A) or failed head involution (C,D). Arrow in E, germband retraction failure. Arrows in F,H, small or large ventral holes. Bottom, frequency of defects for each genotype. Scale bars: 100 µm.
