Df(3L)BSC831 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}CG5931^f02582 and P{XP}brm^d00415. 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; PBac{WH}CG5931^f02582/P{XP}brm^d00415 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}BSC831 from the segment of PBac{WH}CG5931^f02582 to the left of its FRT site and the segment of P{XP}brm^d00415 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(3L)BSC831 predicted from the Release 5 genomic coordinates of the transposable element insertion sites are 3L:15960876 ;15973064 and the cytological breakpoints predicted from these coordinates are 72C1;72C1. Df(3L)BSC831 failed to complement brm².
