Df(1)BSC351 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}CG14439f06522 and P{XP}d06258. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of PBac{WH}CG14439f06522/P{XP}d06258; 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}BSC351 from the segment of PBac{WH}CG14439f06522 to the left of its FRT site and the segment of P{XP}d06258 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)BSC351 predicted from the Release 5 genomic coordinates of the transposable element insertions sites are 6C11;6D7. It failed to complement shf2 and sov2.
