Unc. Head muscles degenerative. Recessive. M-MATING+POOR <1%WT.

Hermaphrodites are Dpy and Him. Males are non-Dpy and Mab. Males have abnormal bursa and defective rays. Both sexes show lateral hypodermis lineage defexts. M-MATING+POOR <1%WT.

Him. M-MATING+POOR <1%WT. Tail abnormalities->knob-like swelling in larvae and adults.

Heterozygotes are WT and segregate WT, Dpy, and Long Thin Steriles (adults lay no or few eggs). lin-23 animals have excess cell divisions in larval blast cell lineages.

Heterozygotes are WT and segregate WT, Dpys, and steriles. mig-6(e1931) hermaphrodites are sterile, with failure of DTC migrations. Gonad sterile, disorganized, otherwise hermaphrodites appear normal. Strain is imperfectly balanced - check for correct segregation of Dpy and Mig from WT hermaphrodites.

WT heterozygote, fem-1(e1965) maternal. Segregates WT heterozygotes, WT fem-1 homozygotes that give only fertile female progeny, and UncMor. (Probably has lost mor-2 [Edgley, 4/92]. When confirmed, should be given a new strain name.)

WT phenotype. tra-3 amber mutant carrying homozygous linked amber suppressor.

Obligate XX female, XO male strain. Maintain by mating. e2020 is a dominant mutation transforming XX into fertile females. XO animals are partly feminized by starvation or elevated temperatures, therefore the strain cannot be grown at 25C.

Shrinker-contracts both dorsally and ventrally when prodded. Slow, poor backing. Slightly small. M-MATING++ 1-10%WT

Unc. Recessive. Levamisole resistant. M-MATING++ 1-10%WT. Also contains an unc-11 mutation->Aixa Alfonso 10/94. See WBPaper00002195. Use ZZ37 for unc-63 reference strain.

Partly or completely suppressed Dpy.

Non-Dpy 4A;3X hermaphrodites segregating 4A;3X hermaphrodites, 4A;2X males and dead or very dumpy 4A;4X hermaphrodites. Reference: Strain 19 in Hodgkin (2002) PMID: 12399387

Hets are Unc and segregate Unc, WT hermaphrodites and dead eggs. The WT hermaphrodites segregate only abnormal sterile males or intersexes. Maintain by picking Unc.

Severely Uncoordinated; Him; feminized at temperatures above 20C. Grow at 15C. Used for generating patroclinous WT males, by exploiting non-disjunction caused by him-8, and dominant sex-linked unc-1.

eIs2137 [sup-7(+) + Dm-hsp::lacZ] IV. lacZ expression induced by heat shock. Limited pattern (the pSHZ1 vector was originally designed for use in Drosophila, not C. elegans, and is not the best vector for expression of lacZ in the worm). This strain has predominantly historical value (as the first C. elegans strain shown to express a foreign gene). eIs2137 transgene is integrated and contains two plasmids: pAST (sup-7 amber suppressor), and pSHZ1 (lacZ driven by Drosophila heat shock promoter (S. Munro)).

Heterozygotes are WT and segregate WT and DpyUnc. 1/3 of the WT are fem-2 homozygotes. Homozygous fem-2 animals are hermaphrodites if mother was heterozygous for fem-2, and are fertile females if mother was homozygous for fem-2.

Temperature sensitive. Sterile at 25C. Maintain at 15C. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects. [2/98: Craig Mello noticed a different embryonic phenotype in this strain as compared to the e2141 stock that Jim Priess obtained from England-the ABp fate appears WT.] [NOTE (11/16/10 - J. Hubbard): This strain is NOT synonymous with glp-1(e2144) as previously reported in Kodoyianni V, Maine EM, Kimble J. (1992) [Molecular basis of loss-of-function mutations in the glp-1 gene of Caenorhabditis elegans. Mol Biol Cell. 3,1199-213. PMID: 1457827]. As reported in Worm Breeders Gazette December 2010; 18(3), e2144 carries the mutation c2785t in exon 8, leading to the amino acid change L929F, whereas e2141 carries the mutations c2920t and a3610g in exon 8, leading to the amino acid changes R974C and T1204A.]

Phenotypically wildtype XX hermaphrodite at 20C; poor viability and fertility at 25C. Rare XO animals are hermaphrodite due to suppression of amber mutation e2115 and consequent transformation of XO due to tra-2(e2046) gain-of-function. Reference: Hodgkin & Albertson (1995) PMID: 8647390.

Anterior displacement of rays and fan. Ray identities are not altered. Slightly Unc (coiler).

Viable Dpy at 15C. Extreme Dpy or L1 lethal at 25C.

sup-34 is dominant amber suppressor: weak suppression of Unc, medium suppression of Dpy.

Hermaphrodites have an abnormal protrusive vulva. Segregate males with abnormally swollen bursa. Suppressor of certain alleles of certain genes.

Hermaphrodites have an abnormal protrusive vulva. Segregate males with abnormally swollen bursa. ma116 is a weak recessive suppressor of certain alleles of certain genes.

Heterozygotes mostly fertile at or below 20C; all sterile at 25C. Progeny are fertile heterozygotes with variable Gon abnormality, e1254 homozygotes (strong Gon, "white patch" phenotype) and eDf18 homozygotes (embryonic lethal). See also WBPaper00003841.
