Heterozygotes are WT and segregate WT, RolUncs and dead eggs. Homozygous wDf1 embryos arrest uniformly as unenclosed balls of differentiated cells. wDf2 formerly called zen-1(w1). sc8 previously called rol-4(sc8).

Resistant to germ cell death induced by ionizing radiation. Sensitive to hypoxia and starvation stresses. This strain contains an intact copy of the gene at the normal locus on LG I. w40 is a translocated partially deleted copy of the cep-1 locus that has a dominant-negative effect on cep-1 function and is not linked to the chromosomal location of cep-1.

Heterozygotes are WT and segregate WT, DpyUncs and dead eggs. Homozygous wDf1 embryos arrest uniformly as unenclosed balls of differentiated cells. wDf1 formerly called zen-1(e2482). 2/02: dpy-21 appears to have been lost from this strain.

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.

Temperature sensitive dauer constitutive. Highly penetrant at 25C, much less so at 20C and 15C. The dauers recover almost immediately after temperature down shift, so one may work with synchronous broods. Semi-dominant: about 10% of heterozygotes form dauers.

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).

Enteric and egg-laying muscle structures are normal. Semi-dominant for Egl defect, but not for constipation defect. n2372/+ : ME3. ES3: adult heterozygotes and homozygotes.

Lon. Daf-d. Suppresses Daf-c phenotype of daf-19(m86). Dyf.

Defective in enteric muscle contraction (expulsion) step of defecation motor program and egg-laying (severe bloating- Egl Type A). Enteric and egg-laying muscle birefringence normal.

Recessive, early stop mutation within the coding sequence (C to T substitution in aa52) makes sa734 a likely null allele. May grow slightly better at 15C. Hyperactive, lays early stage eggs, increased amplitude of locomotort wave-form. Suppresses the lethargy and egg-laying defects of unc-43(n498). Reverses direction of locomotion more frequently than WT.
