Strain Genotype Description
CA538 rad-51(lg8701)/mIs11 IV. mIs11 [myo-2p::GFP + pes-10p::GFP + F22B7.9::GFP]. GFP expression in 4-cell embryos, pharyngeal muscle and gut. Heterozygotes are WT with dim GFP signal in the pharynx. mIs11 homozygotes are WT with bright GFP in the pharynx. rad-51(lg8701) homozygotes are non-GFP and throw dead eggs. Pick WT with dim GFP+ in pharynx to maintain. mIs11 homozygotes will quickly overtake the population if not selected against.
SSM264 rad-51(iow53[GFP::rad-51])/nT1[qIs51] (IV;V). 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.
TG5 rad-51(lg8701) IV/nT1 [let-?(m435)] (IV;V). Heterozygotes are WT and segregate WT and dead eggs. 1/3 of the WT are rad-51(lg8701) homozygotes and will give only dead eggs.
TG9 dpy-13(e184) rad-51(lg8701) IV/nT1 [let-?(m435)] (IV;V). Heterozygotes are WT and segregate WT, Dpys which give only dead eggs, and dead eggs.
VC1873 rad-51(ok2218) IV/nT1 [qIs51] (IV;V). Y43C5A.6. Homozygous sterile deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok2218 homozygotes (sterile, lays eggs that don't hatch). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: TCTTACCTCATTCTTGGCCG. External right primer: GTTCCTATCGGTGCCTTTCA. Internal left primer: TGAATCCGTGAAAGTGTGGA. Internal right primer: AGGACTTGGCACGTGTCTCT. Internal WT amplicon: 2435 bp. Deletion size: 1634 bp. Deletion left flank: AACGAACGGCTAGTCCTCGCGTGCGTCCTC. Deletion right flank: TGATACTTTCAATTCAATTAATTGGATTTT.
