Fig. 6. Dally colocalizes with and stabilizes Hh. (A,B) Hh staining (red) in wing discs expressing GFP-Dly (green) under the control of hh^Gal4 (A) or ptc^Gal4 (B). Hh staining and GFP-Dly in boxed areas are shown separately in small panels. (C-C') Hh staining in a wing disc carrying a sfl^9B4 mutant clone (marked by the absence of GFP in C'). The AP boundary is determined by Ci staining (not shown) and marked by solid lines. The clone is outlined with broken lines. (D,E) Hh staining (green) in a stage 9 wild-type (D) or dly^A187 (E) embryo. The Hh expressing cells are determined by En expression (red).
