Df(3L)BSC737 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}f04990 and P{XP}d09500. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of w1118; P{hs-hid}3, Dr1/TM6C, Sb1 cu1 females crossed to P{hsFLP}1, y1 w1118; PBac{WH}f04990/P{XP}d09500 males. The 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}BSC737 from the segment of PBac{WH}f04990 to the left of its FRT site and the segment of P{XP}d09500 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)BSC737 predicted from the Release 5 genomic coordinates of the transposable element insertion sites are 70B1;70C10. Df(3L)BSC737 failed to complement Df(3L)Exel6119 and Gl1.
