UAS regulatory sequences drive expression of a DsRed(Unk) fluorescent protein. A genomic fragment containing the mir-3 pre-miRNA hairpin has been inserted into the DsRed(Unk) 3'UTR.
Surviving adults expressing mir-3Scer\UAS.T:Disc\RFP under the control of Scer\GAL4Bx-MS1096 have small wings, which are spoon shaped or folded.
