Df(2L)BSC184 was isolated as a FLP recombinase-induced recombination event involving P{XP}d06368 and PBac{WH}CG9135f03307. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of P{hsFLP}1, y1 w1118; P{XP}d06368/PBac{WH}CG9135f03307 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.WH5}BSC184 from the segment of P{XP}d06368 to the left of its FRT site and the segment of PBac{WH}CG9135f03307 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(2L)BSC184 predicted from the Release 4 genomic coordinates of the transposable element insertion sites are 26A8;26B5. It failed to complement eIF-4a02439 and ifc1.
