Df(3R)BSC139 was isolated as a FLP recombinase-induced recombination event involving P{XP}d06295 and PBac{WH}f05678. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of w1118; P{hs-hid}3, Dr1/TM6B females crossed to P{hsFLP}1, y1 w1118; P{XP}d06295/PBac{WH}f05678 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}BSC139 from the segment of P{XP}d06295 to the left of its FRT site and the segment of PBac{WH}f05678 to the right of its FRT site. The cytological breakpoints of Df(3R)BSC139 predicted from the transposable element insertions sites using release 4 coordinates are 82F8;83A3.
Df(3R)BSC139 failed to complement kkv1.
