interommatidial bristle & socket
sensillum trichodeum & trichogen cell
bftΔ263a/bft24 flies show loss of approximately 80% of interommatidial bristles.
bftΔ263a-G4/bft24 flies show loss of interommatidial bristles.
45% of the expected number of homozygotes survive. Mutant adults lack 50-90% of the interommatidial bristles and in most cases, severely defective structures are seen where the interommatidial bristles normally form. The sockets may be abnormal. Third instar mutant larvae often have abnormal trichoid sensilla in which the shaft is missing.
mir-bft24/mir-bftΔ263a has visible phenotype, enhanceable by Df(3L)X-21.2/mir-263bΔ
mir-bft24/mir-bftΔ263a has visible phenotype, suppressible by Scer\GAL4mir-263b-Δ-G4/mir-263bUAS.DsRed2

The loss of interommatidial bristles seen in bftΔ263a/bft24 flies is significantly enhanced if the flies are also carrying mir-263bΔ/Df(3L)X-21.2.
Expression of mir-263bScer\UAS.T:Disc\RFP-DsRed2 under the control of Scer\GAL4mir-263b-Δ-G4 rescues the loss of interommatidial bristles which is seen in bftΔ263a/bft24 flies.
mir-bft24/mir-bftΔ263a is partially rescued by mir-bftUAS.DsRed2
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.
