Df(2R)BSC347 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}CG10936f02448 and P{XP}d02678. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of P{hsFLP}1, y1 w1118; PBac{WH}CG10936f02448/P{XP}d02678 males crossed to w1118; P{hs-hid}2, wgSp-1/CyO females. These males 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}BSC347 from the segment of PBac{WH}CG10936f02448  to the left of its FRT site and the segment of P{XP}d02678 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(2R)BSC347 predicted from the Release 5 genomic coordinates of the transposable element insertions sites are 54D2;54E9. It failed to complement sub1 and Df(2R)Exel7149.
