Expression of UbxIVa.Scer\UAS.cRa under the control of Scer\GAL4sd.PU results in a lack of costal bristles on the wing.
Expression of UbxIVa.Scer\UAS.cRa under the control of Scer\GAL4Bx-MS1096 or Scer\GAL4sd.PU results in transformation of wing into haltere.
Expression of UbxIVa.R.Scer\UAS under the control of Scer\GAL4sca-109-68 does not block apical bristle development.
The partial transformation of haltere into wing which is seen in UbxLDN/Ubxabx-1 Ubxbx-3 Ubxpbx-1 flies is partially suppressed by expression of one copy of UbxIVa.Scer\UAS.cRa under the control of Scer\GAL4Ubx-LDN and is almost completely suppressed by expression of two copies of UbxIVa.Scer\UAS.cRa under the control of Scer\GAL4Ubx-LDN.
