Moderate resistance to ivermectin. NOTE: originally described as carrying ad1302, but reported to actually be ad1305; see strain JD740 for verified avr-14(ad1302) I; avr-15(ad1051) V double mutant. Do not distribute this strain; other labs should request it from the CGC.

Bacteria. Str-R. L10 papilla 2; sporulation-defective mutant. This is a low-quality food that is difficult for the worms to eat, and is useful for studies of the effect of food on behavior, physiology, etc. [NOTE: This strain grows better on NGM than on LB media in CGC.] Described in J Exp Biol 206: 2441-2457. Biosafety Level: BSL-1.

Extensively backcrossed to N2. Background strain for most of the feeding-defective mutant screens.

Eat mutant. Slippery pharynx. Slight relaxation defect.

Eat mutant. Strong Unc Eat. Jerky backward Unc. Hypomorph.

Eat mutant. Slippery isthmus, corpus and grinder.

Eat mutant. Stuffs corpus and isthmus. Abnormality in m6 and m7 contraction timing. Displays clumping behavior; isolated in an RC301 background, so it's likely to have the RC301 bor-1 mutation.

Unc. Eat mutant. Slippery pharynx-Slight relaxation defect.

Bacteria. E. coli. Str-R. Uracil auxotroph. DA837 is derived from OP50. DA837 is harder for worms to eat than most E. coli strains. Some mild Eat mutant worms are easier to distinguish from WT when grown on DA837 than when grown on other E. coli strains. Biosafety Level: BSL-1.

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.
