From: kcook@XXXX Subject: Isolation and characterization of Df(1)BSC709 Date: December 28, 2008 1:14:33 PM GMT- 05:00 Isolation and characterization of Df(1)BSC709 Stacey Christensen, Kim Cook and Kevin Cook Bloomington Stock Center Indiana University Df(1)BSC709 was isolated as a FLP recombinase-induced recombination event involving PBac{RB}e04344 and P{XP}CG32813d00423. The deletion was isolated as a chromosome carrying two copies of the miniwhite marker in progeny of PBac{RB}e04344 w1118/P{XP}CG32813d00423 w1118; MKRS, P{hsFLP}86E/+ females crossed to Binsinscy/Y males. These females 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{XP3.RB5}BSC709 from the segment of PBac{RB}e04344 to the left of its FRT site and the segment of P{XP}CG32813d00423 to the right of its FRT site. The cytological breakpoints of Df(1)BSC709 predicted from the Release 5 genomic coordinates of the transposable element insertions sites are 1E4;2A1. It failed to complement fs(1)N4. __________________________________________________________ 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.
