Df(3R)BSC685 was isolated as a FLP recombinase-induced recombination event involving P{XP}d08171 and PBac{WH}oa2f02819. 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; P{XP}d08171/PBac{WH}oa2f02819 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}BSC685 from the segment of P{XP}d08171 to the left of its FRT site and the segment of PBac{WH}oa2f02819 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(3R)BSC685 predicted from the Release 5 genomic coordinates of the transposable element insertions sites are 94A6;94B2. Df(3R)BSC685 failed to complement epsin-like03685.
