Df(1)BSC766 was isolated as a FLP recombinase-induced recombination event involving P{XP}d00989 and PBac{WH}f06473. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of P{XP}d00989/PBac{WH}f06473; MKRS, P{hsFLP}86E/+ females crossed to Binsinscy/Y males. These females were heat shocked as larvae as described in Parks et al., Nature Genetics 36: 288-292, 2004 (FBrf0175003). This cross and crosses in preceding and succeeding generations maintained the original genetic background of the Exelixis insertion stocks (Thibault et al., Nature Genetics 36: 283-287, 2004; FBrf0175002). The recombination event generated the genetic element P+PBac{XP5.WH5}BSC766 from the segment of P{XP}d00989 to the left of its FRT site and the segment of PBac{WH}f06473 to the right of its FRT site. Its presence was verified using the PCR methods and primers described in Parks et al. The cytological breakpoints of Df(1)BSC766 predicted from the Release 5 genomic coordinates of the transposable element insertion sites are 11E9;12A7. Df(1)BSC766 heterozygotes have a Minute phenotype from deletion of RpS15Aa.
