Expression of DrefdsRNA.t-t.Scer\UAS under the control of Scer\GAL4GMR.PS can result in a rough eye phenotype, depending on the P{UAS-Dref.IR.t-t} insertion line used.
Expression of DrefdsRNA.t-t.Scer\UAS under the control of Scer\GAL4en-e16E can result in lethality, or can result in a notched wing phenotype, depending on the P{UAS-Dref.IR.t-t} insertion line used.
