Df(2L)BSC213 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}Nosf02469 and P{XP}aubd04301. The deletion was isolated as a chromosome lacking miniwhite markers in progeny of P{hsFLP}1, y1 w1118; PBac{WH}Nosf02469/P{XP}aubd04301 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}BSC213 from the segment of PBac{WH}Nosf02469 to the left of its FRT site and the segment of P{XP}aubd04301 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)BSC213 predicted from the transposable element insertions sites using Release 4 coordinates are 32B1;32C1. It failed to complement piwi06843.
