Heterozygotes are wild-type with pharyngeal-expressed GFP, and segregate wild-type GFP+(pharynx) heterozygotes, arrested nT1[qIs51] homozygotes, and viable non-GFP(pharynx) rad-51(iow53[GFP::rad-51]) homozygotes. Balancer is prone to breaking down. If a population contains a mix of bright and dim GFP animals, pick dim GFP and check for correct segregation of progeny to maintain. iow53 inserted a GFP tag at the N-terminus of the endogenous rad-51 locus, but the tagged protein is not fully functional. non-GFP(pharynx) rad-51(iow53[GFP::rad-51]) homozygotes form GFP foci in the germline that are mostly spo-11 dependent, and GFP::rad-51 homozygotes have defects in unloading RAD-51. Created by CRISPR using pDD282, therefore may also contain 3XFLAG. Reference: Koury E, et al. Nucleic Acids Res. 2018 Jan 25;46(2):748-764.

Homozygous gfp and 3xflag C’ terminal tag inserting just before the STOP codon of mre-11. The strain is fertile and contains wild type germline (examined by DAPI). GFP is expressed in all germline nuclei. Maintain the strain by picking worms at 20C, no selection required. gfp::3xflag was added by CRISPR/Cas9 using pDD282-based vector.

N-terminal 3xFLAG tag inserted into the endogenous rpa-4 locus using Crispr/Cas9. Homozygous sterile deletion balanced by bli-4- and GFP-marked translocation. Heterozygotes are wild-type with pharyngeal GFP signal, and segregate wild-type GFP heterozygotes, arrested hT2 aneuploids, and non-GFP ok1627 homozygotes. Homozygous hT2[bli-4 let-? qIs48] inviable. Pick wild-type GFP and check for correct segregation of progeny to maintain. Generated in rpa-2(ok1627) background.

Heterozygotes are wild-type with pharyngeal-expressed GFP, and segregate wild-type GFP+(pharynx) heterozygotes, arrested nT1[qIs51] homozygotes, and viable non-GFP(pharynx) ubc-9(iow97[3xFLAG::ubc-9]) homozygotes. Maintain the strain by picking wild-type GFP+ worms and checking for correct segregation of progeny. iow97 was created by CRISPR/Cas9 insertion of a 3xflag tag at the N-terminus of the endogenous ubc-9 locus; however, the tagged protein is not fully functional. SSM491 is a replacement for SSM291: analysis shows that in all parameters tested, SSM491 is identical to SSM291, which was genetically unstable and prone to breaking down.

CRISPR/Cas9 engineering used to insert N-terminal Myc tag into the endogenous rpa-4 locus, N-terminal 3xFLAG tag into the endogenous rpa-2 locus, and N-terminal OLLAS tag into the endogenous rpa-1 locus. SSM559 was generated by crossing rpa-2(iow49) with rpa-1(iow92), followed by CRISPR insertion of the Myc tag into rpa-4.
