Fig. 7. Distribution of Dpp-GFP in dally mutant wing disc. Dpp-GFP was expressed in A/P border cells by dpp-GAL4 and its distribution was monitored. Wild-type for dally gene (A), dally^gem/dally^gem (B-D), and dpp-GAL4/UAS-dally (E) larvae. All discs were heterozygous for dpp^d12 (see Materials and Methods). (F) Intensity profiles for Dpp-GFP in the posterior half of discs with three different genotypes are shown. 10, 8 and 12 samples were used for wild-type (green), dally homozygote (red) and dpp-GAL4/UAS-dally (blue), respectively, to obtain the averaged profiles.
