Df(3R)BSC198 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}f02841 and P{XP}d04754. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of w1118; Dr1/TM6B, Tb1 females crossed to P{hsFLP}1, y1 w1118; PBac{WH}f02841/P{XP}d04754 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}BSC198 from the segment of PBac{WH}f02841 to the left of its FRT site and the segment of P{XP}d04754 to the right of its FRT site. The cytological breakpoints of Df(3R)BSC198 predicted from the transposable element insertions sites using Release 4 coordinates are 84F13;85A2. It failed to complement l(3)84Fk2 and stckEY06672.
