About 11% of the animals should be Vulvaless. n1779 suppresses clr-1.

At 20C about 50% of the hermaphrodites are Egl. Males have an abnormal tail and do not mate.

Heterozygotes are mostly non-Muv (about 20% will be Muv because n1700 is semi-dominant) and non-Unc. Hets segregate Twitchers which die at various larval stages or as Vul adults, because of the maternal effect rescue of n1531 by n1700. The Twitchers will not give viable progeny. Hets also segregate DpyMuvs. The strain segregates males which will mate, though not very well.

At 20C about 50% of the hermaphrodites are Egl.

Animals with the Duplication are WT. Animals which have lost the Duplication are Dpy and Twitchers. Throws both WT and DpyTwitcher males. Maintain by picking WT.

Maintain by picking wild-type animals raised at 25C. Heterozygotes will be wild-type and segregate wild-type, Unc, and Sterile Muv. The phenotype of homozygous lin-13 hermaphrodites segregating from a heterozygous mother depends on the temperature at which the strain was grown. At 25C, homozygous hermaphrodites segregating from a heterozygote are both Muv and sterile. At 20C, ~1/2 of hermaphrodites segregating from a heterozygote are sterile, but only a few are Muv. At 15C, hermaphrodites segregating from a heterozygote are almost wild type in appearance and fertility. However, if the progeny of these 15C animals are grown at 15C, all are sterile and some are Muv. If the progeny of these 15C animals are grown at 25C, then some animals arrest during larval growth and the rest are both sterile and Muv. Reference: Ferguson EL & Horvitz HR.

nIs51 [egl-10(+) + lin-15(+)] X. Egl-C, Bor, hyperforaging, hyperactive locomotion, and male longevity and mating reduced. By Western blotting and staining the EGL-10 protein is highly overexpressed relative to N2. nIs51 was generated by injecting the lin-15 rescuing plasmid pEK1 at 50 ug/ml and the egl-10 rescuing fragment pMK21 at 80 ug/ml into MT1642 lin-15(n765) worms. The resulting strain was gamma irradiated and an integrant isolated, and was backcrossed to N2 four times. nIs51 was mapped to the right arm of X.

Heterozygotes are WT and segregate WT, Sterile Dpys, and Mel Uncs. cup-5(n3194) is a Q139 ochre allele with a maternal effect lethal phenotype including accumulation of refractile bodies resembling apoptotic cells in some regards. cup-5 homozygotes are also defective in coelomocyte uptake.

unc-2(e55) is very inactive. gm83 is a Unc (forward kinker). Double shows both phenotypes.

C. elegans var Bristol. Generation time is about 3 days. Brood size is about 350. Also CGC reference 257. Isolated from mushroom compost near Bristol, England by L.N. Staniland. Cultured by W.L. Nicholas, identified to genus by Gunther Osche and species by Victor Nigon; subsequently cultured by C.E. Dougherty. Given to Sydney Brenner ca. 1966. Subcultured by Don Riddle in 1973. Caenorhabditis elegans wild isolate. DR subclone of CB original (Tc1 pattern I). [NOTE: This stock might carry a ~1.8 kb deletion in alh-2 in the background. (UPDATE: 03/26/2018 - a user reported the stock they received was homozygous for the alh-2(ot588) mutation.)]

WT C. elegans. From Cambridge collection-originally frozen around 1968: In 1980, in order to establish an ancestral stock, Jonathan Hodgkin thawed one of the earliest frozen tubes of N2, dating from 1968. From this plate J.H. grew up a population en masse (without subculturing) on NGM plates (about 2 generations). Multiple samples of this were frozen in order to provide a reference N2 stock. This set of stock samples was replenished by regrowth in 1985 and 1991, using the same procedure, and a freshly thawed sample was sent to the CGC in 1993. Thus, samples from this frozen stock, called N2 (ancestral), should be only about 6 generations away from the stock used by Sydney Brenner as his standard WT N2. [Isolated from mushroom compost near Bristol, England by L.N. Staniland. Cultured by W.L. Nicholas, identified to genus by Gunther Osche and species by Victor Nigon; subsequently cultured by C.E. Dougherty. Given to Sydney Brenner ca. 1966.] Caenorhabditis elegans wild isolate. Note: N2 (ancestral) has reduced lifespan and fertility relative to the standard CGC N2 strains. See Worm Breeder's Gazette 16(5): 24 (February 1,2001).

C. elegans var Bristol. Self-fertilizing hermaphrodite. Generation time is about 3.5 days at 20C. Male stock maintained by mating. Also CGC reference 257. Isolated from mushroom compost near Bristol, England by L.N. Staniland. Cultured by W.L. Nicholas, identified to genus by Gunther Osche and species by Victor Nigon; subsequently cultured by C.E. Dougherty. Given to Sydney Brenner ca. 1966. Subcultured by Don Riddle in 1973. Caenorhabditis elegans wild isolate. DR subclone of CB original (Tc1 pattern I). [NOTE: (09/07/2018) The Gems Lab has identified a mutation in the gene fln-2 carried in this stock causing an increased lifespan. The effect is quite modest (+11%, median lifespan), but this effect can be more pronounced in other genetic backgrounds.] [NOTE: (03/26/2018) - a user reported the stock they received was homozygous wild-type for alh-2; some N2 stocks carry the ot588 mutation in alh-2.)

ltSi914 [osm-6p::vhhGFP4::zif-1::operon-linker::mCherry::his-11::tbb-2 3'UTR + Cbr-unc-119(+)] II. Sensory neuron-specific expression of anti-GFP nanobody fused to ZIF-1 mediates sensory neuron-specific degradation of GFP-tagged proteins (through recruited ZIF-1 but NOT requiring ZF1 tags). Can be combined with endogenous locus GFP-tagging or rescue of a null mutant with a GFP fusion to examine sensory neuron-specific functions of target genes.
