WT strain. Isolated by D. Fitch in June 1990 from soil in Scott Emmons' compost heap in the Fort Greene section of Brooklyn, NY. A second strain, DF5038, was isolated from the same location one year later from the head and ventral segments of a male pill bug (Armadillidium vulgare). Hermaphroditic. Males are easily isolated by heat shocking L4 or early adult hermaphrodites at 30C for 6-12 hrs. Grows well at 6-25C on OP50. Dauer larvae accumulate under starved or overcrowded conditions. Freezes easily using C. elegans protocols with 90% viability. Previously called Rhabditis sp. See also WBPaper00003418. Formerly known as Oscheius myriophila.

Temperature-sensitive. Maintain at 15C. Animals form germline tumors that prevent fertility at restrictive temerature (25C). This is the first strain reported to be used for the isolation of germ cells for in vitro culture. This strain allows germ cells to remain viable for longer periods than other tumorous mutant strains tested. Reference: Chaudhari SH, et al. Dev Cell. 2016 Jul 11;38(1):33-46.

Temperature sensitive, embryonic lethal mutant. 98% of embryos produced by homoygous mothers hatch at 15C; 0% produced at 26C hatch (but some viability at 25C). Mutation is recessive at 26C. First mitotic spindle in one-cell zygote is mis-positioned, often abnormally near the posterior pole; some chromosome segregation defects.

Weakly semi-dominant, temperature sensitive, embryonic lethal mutant. 38% of embyros produced by homozygous mothers at 15C will hatch; 2% produced at 26C will hatch. Mutation is semi-dominant at 26C: 12% of embryos produced by heterozygous mothers hatched at 26C, and about 25% of the survivors were or295/or295, indicating the lethality is semi-dominant and maternal. Mutant embyros exhibit excess cortical actomyosin contractility (extra furrows and protrusions) in early embryonic cells, during interphase and most of mitosis. Throws males. or295 is a gga to aga substitution (G16R).

ruIs32 [pie-1p::GFP::H2B + unc-119(+)] III. apo-5(or358) is temperature-sensitive embryonic lethal. 100% dead embryos when L4 larvae are shifted to 26.6C. A small percentage of embryos survive form L4 larvae shifted to 25-26C. or358 appears to be semi-dominant; L4 or358/+ heterozygotes shifted to 26C produce ~20% embryonic lethality. Maintain at 15C.

or28 is a non-conditional maternal-effect embryonic lethal mutant ; the anterior pharynx is absent. and embryonic lethality is 100% penetrant. Pick single WT heterozygous hermaphrodites to maintain strain; these hets fill up with a mix of dead embryos and larvae [11/16 dead embryos due to aneuploidy from translocation segregation and lethal homozygous hT2; vulvaless due to homozygous lin-2(e1309) mutation; about 10% of lin-2(e1309) worms are leaky and lay eggs/can be mated into]. The homozygous or28 hermaphrodites fill up with dead embryos. The lin-2 background helps to score embryonic lethality for both heterozygotes and or28 homozygotes. or28 is a G to D mis-sense mutation at amino acid position 123.

Heterozygotes are WT and segregate WT, Lon males, lots of dead eggs, and Dpys. The Dpys should give all dead embryos at all temperatures. Approximately 60% of these dead embryos make excess mesoderm at the expense of endoderm, due to an E to MS fate transformation. Embryonic lethality is 100% penetrant for or46.

Heterozygotes are WT and segregate WT and Uncs. The Uncs have a non-conditional maternal-effect embryonic lethal phenotype: the E blastomere adopts MS fate in about 5% of mutant embryos. The Uncs are 100% penetrant for embyronic lethality and morphogenesis defects.

Temperature-sensitve sterile. Maintain at 15-20C. Superficially wild-type at permissive temperatures; contains large bubble-like structures on the inside in all stages (described as large early endosomes), reduced brood size. Sterile and very sick at 25°C with some single escapers that are sterile and sick themselves. Suppressors have been observed after long culturing over several months, periodically check for sterility at 25C.

Hypersensitive to copper and cadmium ions, and to starvation. [NOTE: Prior studies suggested possible cross-regulation of PMK-1 by MEK-1, but the identification of a tightly linked partial loss-of-function mutation in sek-1(qd127) in the strain carrying the mek-1(ks54) mutant allele (K. Reddy and D. Kim, unpublished data) suggests that the diminished PMK-1 activation observed in this mutant strain may actually be due to diminished SEK-1 activity.]
