Deletion that removes the terminal 323 amino acid residues (52%) of the Ir92a coding sequence, including all transmembrane domains. A sequence cassette containing a Disc\RFPDsRed(T1).3xP3.cHa marker flanked by loxP sites, plus a single attP site, has been inserted in place of the deleted sequence
The 3xP3-DsRed marker from the pHD-DsRed-attP vector replaced genomic region 3R:20 ,342,366-20,344,610.
