UASt regulatory sequences drive expression of DsRed2 followed by a 3'UTR into which a 300bp genomic fragment containing the mir-263a miRNA hairpin (which is encoded by bft) has been cloned.
Scer\GAL4sca.PU, mir-bftUAS.DsRed2, miGD11624 has lethal phenotype
Scer\GAL4mir-bft-Δ263a-G4/mir-bftUAS.DsRed2 rescues mir-bft24/mir-bftΔ263a-G4
mir-bftUAS.DsRed2 partially rescues mir-bft24/mir-bftΔ263a
Expression of bftScer\UAS.T:Disc\RFP-DsRed2 under the control of Scer\GAL4bft-Δ263a-G4 rescues the loss of interommatidial bristles which is seen in bftΔ263a-G4/bft24 flies.
Leaky expression of bftScer\UAS.T:Disc\RFP-DsRed2 in the absence of a Scer\GAL4 driver partially rescues the loss of interommatidial bristles which is seen in bftΔ263a/bft24 flies.
