Encodes an ovo-A-like isoform (carries the nucleotide substitution A1282T).
adult thorax & microchaeta, with Scer\GAL4Bx-MS1096
adult thorax & trichome, with Scer\GAL4Bx-MS1096
eye, with Scer\GAL4GMR.PF
Expression of ovoD1.Scer\UAS.cAa under the control of Scer\GAL4Bx-MS1096 strongly reduces trichome density in the thorax. The microchaete shafts fail to extend and have an abortive morphology. Wing hair formation is prevented and the wing has a naked surface. Pupal F-actin prehairs in the wing are not formed in these animals. Clones in the wing expressing ovoD1.Scer\UAS.cAa under the control of Scer\GAL4αTub84B.PP that are induced up to 8 hours after puparium formation (APF) prevent actin prehair formation or strongly reduced the length of prehairs. Clones induced up to 18 hours APF impair prehair formation. Expression of ovoD1.Scer\UAS.cAa under the control of Scer\GAL4GMR.PF results in a reduction in eye size with ommatidial fusions and a lack of bristles.
Expression of ovoD1.Scer\UAS.cAa in the embryo under the control of Scer\GAL4e22c results in naked cuticle.
