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(1)BSC834 predicted from the Release 5 genomic coordinates of the progenitor PBac{WH}dncf00210 and P{XP}ecd05241 transposable element insertion sites are X:3182989 ;3739760 and the cytological breakpoints predicted from these coordinates are 3C11;3F3.
