krIs14 [hsp-16.48p::MosTransposase + lin-15(+) + unc-122p::GFP] V. Recessive Unc. unc-5(lib1) is a CRISPR/Cas9 engineered mutant carrying the Intersister/Intrachromatid Repair Assay (ICR Assay) cassette inserted into the endogenous unc-5 locus. Briefly, ICR assay cassette includes two tandem GFP cassettes: the upstream using the myo-3 (body wall) promoter with a truncated GFP coding sequence, and the down-stream using the myo-2 (pharynx) promoter with GFP coding sequence interrupted by a Mos1 Drosophila transposon. Excision of Mos1 yields a single DSB, which if repaired by intersister or intrachromatid recombination, then will yield GFP+ progeny. The krIs14 insertion carrying heat-shock inducible Mos1 transposase is marked with coelomocyte GFP expression. Reference: Toraason E, et al.
