Fig. 1. dly is required for Hh signalling in embryogenesis. All cuticles are oriented anterior towards the left. (A-C) Ventral views are shown. Cuticle preparation of the wild-type first instar larva (A), hh^IJ35 homozygous embryo (B) and dly^A187 mutant embryo derived from a dly^A187 germline clone (C). (D-I) All embryos are oriented anterior towards the left and dorsal upwards. En staining in stage 10 wild-type (D) and dly^A187 mutant (E) embryos. (F,G) wg transcription in stage 10 wild-type (F), and dly^A187 mutant (G) embryos visualized by in situ hybridization. (H,I) bap transcription in stage 10 wild-type (H) and dly^A187 mutant (I) embryos visualized by in situ hybridization.
