UAS regulatory sequences drive expression of a DsRed(Unk) fluorescent protein. A genomic fragment containing the mir-278 pre-miRNA hairpin has been inserted into the DsRed(Unk) 3'UTR.
Expression of mir-278Scer\UAS.T:Disc\RFP under the control of Scer\GAL4dpp.PU results in overgrowth of the L3-L4 intervein region.
