Embryonic expression of group B genes in D. melanogaster and D. pseudoobscura. A-H, D. melanogaster. A'-H', D. pseudoobscura; anterior is to the left in all cases. A-A') Lateral view of stage 5 embryos showing expression of Dichaete in a central domain and the cephalic neuroectoderm. B-B') Lateral views of stage 8 embryos showing extensive Dichaete expression in the developing CNS. C-C') Ventral view of stage 5 embryos showing SoxN expression is restricted from the presumptive mesoderm. D-D') Dorsal view of stage 8 embryos showing SoxN expression in the CNS. E-E') Lateral view of stage 9 embryos showing Sox21a expression in the anlage of the foregut and hindgut. F-F') Ventral views of stage 14 embryos showing Sox21a expression restricted to specific cells in the midline. G-G') Lateral views of stage 13 embryos showing Sox21b expression in abdominal epidermal stripes. H-H') Ventral view of stage 14 embryos showing Sox21b expression in abdominal epidermal stripes.
