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),
hhIJ35 homozygous embryo (B) and
dlyA187 mutant embryo derived from a
dlyA187 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 dlyA187 mutant (E) embryos. (F,G)
wg transcription in stage 10 wild-type (F), and
dlyA187 mutant (G) embryos visualized by in situ
hybridization. (H,I) bap transcription in stage 10 wild-type (H) and
dlyA187 mutant (I) embryos visualized by in situ
hybridization.
