Df(3L)BSC365 was isolated as a FLP recombinase-induced recombination event involving P{XP}d10752 and PBac{WH}CG9018f03052. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of w1118; Dr1/TM6C, Sb1 females crossed to P{hsFLP}1, y1 w1118; P{XP}d10752/PBac{WH}CG9018f03052 males. 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}BSC365 from the segment of P{XP}d10752 to the left of its FRT site and the segment of PBac{WH}CG9018f03052 to the right of its FRT site. Its presence was verified using the PCR methods and primers described in Parks et al. The cytological breakpoints of Df(3L)BSC365 predicted from the Release 5 genomic coordinates of the transposable element insertion sites are 62B7;62D3. Df(3L)BSC365 failed to complement sls1 and Df(3L)ED4284. Df(3L)FDD-0116595 is a synonym for Df(3L)BSC365.
