Df(3L)BSC125 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}f04555 and P{XP}d10863. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of w1118, P{hsFLP}1; PBac{WH}f04555/PBac{XP}d10863 females crossed to w1118; wgSp-1/CyO; sensLy-1/TM6B, Tb1 males. The 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}BSC125 from the segment of PBac{WH}f04555 to the left of its FRT site and the segment of P{XP}d10863 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(3L)BSC125 predicted from the transposable element insertions sites are 61B3;61B3. It failed to complement Df(3L)Exel6084.
