Df(2R)BSC880 was isolated as a FLP recombinase-induced recombination event involving P{XP}fdld03111 and PBac{WH}vgf02736. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of P{hsFLP}1, y1 w1118; P{XP}fdld03111/PBac{WH}vgf02736 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{XP5.WH5}BSC880 from the segment of P{XP}fdld03111 to the left of its FRT site and the segment of PBac{WH}vgf02736 to the right of its FRT site. Its presence was verified using the PCR methods and primers described in Parks et al. The breakpoints of Df(2R)BSC880 predicted from the Release 5 genomic coordinates of the transposable element insertion sites are  2R:8384335 ;8781611..8781621 and the cytological breakpoints predicted from these coordinates are 49A9;49E1. Df(2R)BSC880 failed to complement sca2 and Df(2R)Exel7121.
