Detailed Description
Statement
Reference

Ubx1:Cbx-1 adults exhibit partial wing-to-haltere transformation.

89.6% of heterozygotes show substantial loss of posterior wing tissue that often leads to the posterior region folding over the wing. 10.4% of heterozygotes have a large blister on the wing that comprises one third of the entire wing area or show wing necrosis.

Heterozygotes have a wing with an abnormal shape and an alula that is greatly reduced in size.

za, UbxCbx-1/+ flies do not differ from UbxCbx-1/+, whereas the wings of za, Ubx1:Cbx-1/+ are considerably less like halteres than those of Ubx1:Cbx-1/+.

The Cbx phenotype in Ubx1:Cbx-1/In heterozygotes is enhanced by M(2)531.

Ubx1:Cbx-1 heterozygotes show a dominant phenotype of warped and held-out wings because the UbxCbx-1 part acts to misexpress Ubx+ on the homologue. This effect is disrupted by rearrangements that break once in between Ubx and the centromere and once elsewhere.

Reference

The severity of the Ubx1:Cbx-1/+ wing phenotype is dominantly enhanced by Cap-H2Z3-0019, Cap-H2TH1 and Df(3R)Exel6159; in each case the proportion of flies that show blistering or necrosis of the wing is increased.

Expression of Cap-H2Scer\UAS.P\T.T:Disc\RFP-mCherry under the control of Scer\GAL4sd-SG29.1 partially suppresses the Ubx1:Cbx-1/+ wing phenotype.

Expression of Cap-H2EY09979 under the control of Scer\GAL4sd-SG29.1 partially suppresses the Ubx1:Cbx-1/+ wing phenotype.
