A set of ~800 largely isogenic deficiency stocks created by FLP-induced recombination between FRT-carrying transgenic insertions; molecularly defined deletion endpoints correspond to initial location of the progenitor insertions. Designed to fill gaps in deletion coverage and breakpoint placement; also used to replace older available deficiencies that have not been molecularly mapped.
The breakpoints of Df(2R)BSC878 predicted from the Release 5 genomic coordinates of the progenitor P{RS5}5-SZ-3561 and PBac{RB}CG4712e00550 transposable element insertion sites are 2R:9085479..9085997 ;9136746 and the cytological breakpoints predicted from these coordinates are 49F7;49F13.
