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.
An incorrect sequence location for breakpoint 2 of 2R:4 ,732,831 (Release 5), and incorrect estimated cytology for breakpoint 2 of 44F1, was displayed on FlyBase through to the FB2009_10 release.
Breakpoint from FlyBase's release 5 sequence location of progenitor insertion.
The presence of P+PBac{XP5.WH5}BSC267 was verified using the PCR methods and primers described in FBrf0175003.
The cytological breakpoints of Df(2R)BSC267, predicted from the Release 5 genomic coordinates of the progenitor insertion sites, are 44A4;44C4.
