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(3L)BSC815 predicted from the Release 5 genomic coordinates of the progenitor PBac{WH}f07661 and P{XP}d06673 transposable element insertion sites are 3L:8256164 ;8499740 and the cytological breakpoints predicted from these coordinates are 66C3;66D4.
