Wg target gene expression is unaltered in hrs-deficient cells. (A–L) Wing discs with hrs clones marked by the absence of GFP (green in merge). (A–C) Sal expression (red in merge) in (A) WT sibling and (B, C) hrs mosaic disc. Note ectopic Sal expression in an hrs clone straddling the endogenous domain (arrow). (D–F) Vg expression (red in merge) in (D) WT sibling and (E, F) hrs mosaic disc. (G–I) Dll expression (red in merge) in (G) WT sibling and (H, I) hrs mosaic disc. (J–L) Hnt expression (red in merge) in (J) WT sibling and (K, L) hrs mosaic disc. There is no detectable change in Vg, Dll or Hnt expression in hrs clones.
