Pick WT to maintain. Throws WT, Roller Uncs and dead eggs. wDf4 arrests as dead eggs with no gut. sc8 previously called rol-4(sc8).

Unc. Daf-c at 25C. Egl, Clumpy, Lon, low brood size. Dauers do not recover when moved to 15C in the presence of food. Daf-c, Lon, Clumpy and fertility defects can be rescued maternally. Maintain at 15C.

Daf-c strongly but not completely suppressed; some dauers visible at 25C. sa935 alone is moderate Daf-d (dauer defective) in plate starvation assays, and resistant to exogenous dauer pheromone. sa935 confers strong suppression of daf-8 and daf-14, weak suppression of daf-1, -4, -7. scd-2(sa935) single mutant looks WT. snb-1(md247) hypomorph is an excellent balancer for scd-2; snb-1 is immediately neighboring. Maintain at 15 degrees.

Cholesterol concentration-dependent Daf-c. If cholesterol is omitted from NGM, animals form dauers (no dauers are formed on regular NGM). Temperature sensitive Daf-c; heh-1 animals more readily form dauers at 27C than WT animals. Partial dauer phenotype; dauers exhibit ale but do not fully constrict pharynges nor arrest germline proliferation. On low cholesterol, vulva protrudes and sometimes ruptures; animals exhibit egg-laying defects. Hypersensititve to progesterone in culture media.

daf-d. Weak heterochronic phenotypes in seam, somatic gonad, intestine. Class III allele.

Adults Age and Itt, but not Unc (class 1 allele). sa193 results in an amino acid substitution(A580T) in the extracellular portion of the DAF-2 receptor (specifically, the L2 domain).

Defecation motor program executed twice each cycle period. Hyperactive loopy movement. Previously called dec-8(sa200).

Temperature sensitive. Short defecation cycle period at 20C, longer at 25C. Appears to feed normally.

Nrf. sa366 previously called nrf-2.

Semidominant suppressor of lin-12(d) alleles.

Long defecation cycle period. Slightly slow growing and scrawny. Reduced brood size, especially at 25C. See also WBPaper00003693; previously called dec-4(sa73).

Temperature sensitive. Weak allele.

Daf-c at 25C. Egl, Clumpy, Lon, low brood size. Dauers do not recover when moved to 15C in the presence of food. Daf-c, Lon, Clumpy and fertility defects can be rescued maternally. Maintain at 15C.

CRISPR-engineered KO strain of haps-1 made by knock-in of tandem stop codons to the first exon of endogenous haps-1 locus. haps-1(C48B6.3) is the C. elegans ortholog of human HAPSTR1. haps-1(ljt1) is superficially wild-type when cultured at 20C, but is hypersensitive to paraquat (redox stress), MLN4924 (neddylation inhibition), and camptothecin (genotoxic stress).

Mesorhabditis okuensis wild isolate. Male-female strain: maintain by crossing. Typically very few males on plates (only 10%); might be necessary to transfer large chunks to the new plates to ensure enough males are transferred. This species displays a striking reproductive system (described in Grosmaire & al. Science 2019. doi: 10.1126/science.aau0099).
