A set of 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. Initial core set of 209 isogenic deletions provides ~60% euchromatic genome coverage.
Scer\FRT-mediated recombination between the two progenitor insertions has resulted in the deletion of 79,079 bp of genomic sequence between them, including the entire Nedd4 open reading frame and four other genes.
Homozygous Df(3R)ED4688 stage 16 embryos do not display any midline crossing defects.
