Expression of Mes4dsRNA.Scer\UAS.WIZ under the control of Scer\GAL4GMR.PS, Scer\GAL4ey.PH, Scer\GAL4en-e16E or Scer\GAL4Act5C produces no detectable mutant phenotype.
Expression of Mes4dsRNA.Scer\UAS.WIZ under the control of Scer\GAL4ap-md544 results in an upwards curved wing.
Expression of a single copy of Mes4dsRNA.Scer\UAS.WIZ under the control of Scer\GAL4tub results in an atrophied wing. Expression of two copies of Mes4dsRNA.Scer\UAS.WIZ under the control of Scer\GAL4tub results in embryonic lethality.
Expression of of Mes4dsRNA.Scer\UAS.WIZ under the control of Scer\GAL4Bx-MS1096 results in an atrophied wing. Wing discs of these animals show increased BrdU signals in the wing pouch compared to controls.
