Fig. 3. Antp^Ctx show similar adult phenotypes to ectopic Antp in combination with N^act in eye imaginal discs. (A,B) Head of Antp^Ctx an adult showing an ectopic dorsal thoracic structure (Th in A) and wing tissue (W in B) on the dorsal side. (C,D) ey-Gal4>UAS-N^act; UAS-Antp head showing some ectopic thoracic tissue (Th in C) and a wing (W in D) growing out of the dorsal side. (E,F) Heads of OK-107-Gal4>UAS-Antp flies showing the eye reduction phenotype. (G) The addition of bip2 increases the frequency of formation of ectopic wings (W) formed on the head of OK-107>UAS-bip2; UAS-Antp flies. Antp is able to induce ectopic wings without N^act.
