The deletion was isolated as a chromosome lacking miniwhite markers in progeny of w[1118]; Dr[1]/TM6C, Sb[1] females crossed to P{hsFLP}1, y[1] w[1118]; P{XP}d10752/PBac{WH}CG9018[f03052] 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}CG9018[f03052] 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 sls[1] and Df(3L)ED4284. Df(3L)FDD-0116595 is a synonym for Df(3L)BSC365. __________________________________________________________ Kevin Cook, Ph.D. Bloomington Drosophila Stock Center Department of Biology http://flystocks.bio.indiana.edu Jordan Hall 142 Indiana University 812-856-1213 1001 E.
