      Detailed Description
      Statement
      Reference

      Flies carrying two copies of PsnL235P.Scer\UAS expressed under the control of Scer\GAL4GMR.PF have wild-type eyes. Flies carrying two copies of Psn+14.Scer\UAS expressed under the control of Scer\GAL4GMR.PF have a rough eye phenotype, which is enhanced if the flies are also carrying one copy of PsnL235P.Scer\UAS. Does not affect the eye phenotype of flies expressing rprGMR.PH when expressed under the control of Scer\GAL4GMR.PF.
