Df(2L)BSC147 was isolated as a FLP recombinase-induced recombination event involving PBac{RB}CG9267e01101 and P{XP}d11348. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of P{hsFLP}1, y1 w1118; PBac{RB}CG9267e01101/P{XP}d11348 males crossed to w1118; P{hs-hid}2, wgSp-1/CyO 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.RB3}BSC147 from the segment of PBac{RB}CG9267e01101 to the left of its FRT site and the segment of P{XP}d11348 to the right of its FRT site. Its presence was verified using the PCR methods and primers described in Parks et al. with the substitution of the primer 5'-CCAATGCGTTTATTTCAGGTCACG-3' for the RB3' minus primer in the Hybrid PCR protocol in the Supplementary Methods. The cytological breakpoints of Df(2L)BSC147 predicted from the transposable element insertions sites using Release 4 coordinates are 34C1;34C6. It failed to complement kuz3 and Df(2L)b87e25.
