hLhx2 rescues the wing phenotype of ap mutants. (A) Wing imaginal disc expressing UAS:lacZ from the ap-GAL4^MD544 driver. This GAL4 P-element insertion in ap inactivates the gene and recapitulates its expression pattern. (B) ap-GAL4^MD544/ap^UGO35 mutant fly. Note the lack of wings, halteres, and the scutellum region of the notum. (C and D) ap-GAL4^MD544/ap^UGO35 mutant flies carrying the UAS:ap and UAS:hLhx2 transgenes, respectively. Note that, in both cases, the wing, notum (white arrow), and haltere (black arrow) phenotypes are rescued.
