Df(2L)BSC688 was isolated as a FLP recombinase-induced recombination event involving P{XP}d02064 and PBac{WH}f07743. The deletion was isolated as a chromosome carrying two copies of the miniwhite marker in progeny of P{hsFLP}1, y1 w1118; P{XP}d02064/PBac{WH}f07743 males crossed to w1118; P{hs-hid}2, wgSp-1/SM6a 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{XP3.WH3}BSC688 from the segment of P{XP}d02064 to the left of its FRT site and the segment of PBac{WH}f07743 to the right of its FRT site. The cytological breakpoints of Df(2L)BSC688 predicted from the Release 5 genomic coordinates of the transposable element insertions sites are 22B1;22D6. Df(2L)BSC688 failed to complement Df(2L)Exel8005 and l(2)s5379s5379.
