Expression of Mmus\Med29 is governed by UASp regulatory sequences.
Mmus\Med29UASp.cSa, Scer\GAL4αTub84B.PL, ix3 has visible | dominant phenotype
Mmus\Med29UASp.cSa, Scer\GAL4αTub84B.PL, ix3/ix[+] has visible phenotype
Mmus\Med29UASp.cSa/Scer\GAL4αTub84B.PL is a non-suppressor of abdominal tergite 6 | female phenotype of Df(2R)en-B/ix3
Mmus\Med29UASp.cSa/Scer\GAL4αTub84B.PL is a non-suppressor of cercus | female phenotype of Df(2R)en-B/ix3
Mmus\Med29UASp.cSa/Scer\GAL4αTub84B.PL is a non-suppressor of hypogynial long bristle phenotype of Df(2R)en-B/ix3
Mmus\Med29UASp.cSa/Scer\GAL4αTub84B.PL is a non-suppressor of prothoracic metatarsal segment transverse row bristle | female phenotype of Df(2R)en-B/ix3
Mmus\Med29UASp.cSa, Scer\GAL4αTub84B.PL, ix3 has abdominal tergite 6 | female phenotype
Mmus\Med29UASp.cSa, Scer\GAL4αTub84B.PL, ix3 has hypogynial long bristle phenotype
Mmus\Med29UASp.cSa, Scer\GAL4αTub84B.PL, ix3 has cercus | female phenotype
Expressing Mmus\IxlScer\UAS.P\T.cSa in the fly, under the control of Scer\GAL4αTub84B.PL does not rescue the ix3/Df(2R)en-B phenotype. The pigmentation of abdominal tergite 6 was male-like, the anal plates were shifted laterally, the vaginal teeth were reduced in number and not present in rows and the last transverse row bristles, which form the sex combs in the male, were darker, thicker, and rotated upwards, as in the male. Expressing Mmus\IxlScer\UAS.P\T.cSa under the control of Scer\GAL4αTub84B.PL in heterozygous ix3 females yields a strong intersexual transformation. Indeed females heterzygous for endogenous ix and expressing Mmus\IxlScer\UAS.P\T.cSa are indistinguishable from females homozygous ix3 mutant and expressing Mmus\IxlScer\UAS.P\T.cSa, suggesting that Mmus\IxlScer\UAS.P\T.cSa acts in a dominant-negative manner.
