Overexpression of Ubx::Hrob\Lox2Scer\UAS.cCa driven by Scer\GAL4dpp.blk1 causes transformation of the antenna towards a thoracic leg. Overexpression of Ubx::Hrob\Lox2Scer\UAS.cCa driven by Scer\GAL4Bx-MS1096 causes transformation of the wing towards a haltere. This transformation is more severe in males than in females. The phenotype is stronger on the dorsal surface of the wing. Overexpression of Ubx::Hrob\Lox2Scer\UAS.cCa in the ectoderm, driven by Scer\GAL4arm.PS, transforms the denticle belts of thoracic segments towards A1 identity. The development of Keilin's organs and ventral pits are repressed.
