Bacteria. E. coli HT115(DE3) bacterial strain carrying pGC8. pGC8 is a partial cDNA of him-14 (ZK1127.11) cloned into the Timmons and Fire "double T-7 vector" L4440. The source of the cDNA is Yuji Kohara's clone yk240h12. pGC8 was constructed by inserting the 1.65kb KpnI/SacI fragment of the him-14 cDNA (from base pair 1071 to 192 base pairs beyond the stop codon) into the same sites in L4440. HT115(DE3) carrying pGC8 should be selected in the presence of 50 um/ml tetracyline and 100 um/ml ampicillin. Prior to an actual feeding experiment, it can be grown in liquid in the presence of amp alone (no tet) and then seeded onto NGM plates containing amp and 1 mM IPTG. This technique does not work well if the cells are old; therefore, the strain should be seeded onto IPTG-containing plates from a fresh overnight that was grown from a colony on an amp/tet plate. Biosafety Level: BSL-1. For more info see http://www.wormbook.org/wli/wbg17.1p32/

K10D2.3 Slow development. Reduced fertility. Thermotolerant. Resistant to hydroxyurea.

zcIs13 [hsp-6p::GFP + lin-15(+)] V. Stable transgenic line with GFP expression mainly in the posterior intestine, observed from L1 to adult. Perturbation of mitochondrial folding environment induces robust GFP expression throughout the intestines. Derived by outcrossing parental strain SJ4100 to N2 six times to remove suspected background mutations causing uneven transgene expression and low penetrance of sterility.

pgIs2 [gcy-8p::TU#813 + gcy-8p::TU#814 + unc-122p::GFP + gcy-8p::mCherry + gcy-8p::GFP + ttx-3p::GFP]. TU#813 and TU#814 are split caspase vectors (Chalfie Lab) subcloned downstream of the gcy-8 promoter. Expression of GFP in coelomocytes and AIY neuron, and mCherry in AFD neuron when caspase activity is lost. Reference: Glauser DA, et al. Genetics. 2011 May;188(1):91-103.

Slow pumping. Egg laying defective. Low frequency of dauer formation. Residual serotonin immunoreactivity, rare and very faint (<1% of NSMs) in most stages, but nearly 100% of CP neurons in adult males show faint to moderate serotonin immunoreactivity. Males mate quite well (E. Hare and C. Loer). Some phenotypic defects originally attributed to mg280 in this strain are likely due to vs166. vs166 is a large deletion (approx. 9.8kb) in the cam-1 gene; flanking sequences are: 5'-gctactggtaaataaggtaa-3' and 5'-atgcttttaaagtttatatt-3' (Edith Myers, personal commnication). See MT15434 for a strain carrying mg280 without the cam-1 mutation.

Caenorhabditis elegans wild isolate. Isolated from soil under a Kiwi fruit tree in a botanical garden in Wuhan City, Hubei Province, China, on Nov 11, 2010. Lat: 30° 32' 34.40" N; Lon: 114° 25' 11.38" E. This strain was whole-genome sequenced as part of the Million Mutation Project (MMP).

rtSi10 [smn-1p::smn-1 + Cbr-unc-119(+)] IV. nuIs175 [myo-2p::RFP + unc-129p::RFP::snb-1] X. rtSi10 transgene partially rescues smn-1(ok355): smn-1 homozygotes normally arrest as larvae, but somatic defects, including late larval lethality, are ameliorated by rtSi10. Sterility in smn-1(ok355) homozygotes is not rescued by rtSi10. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP ok355 homozygotes (sterile due to partial rescue by rtSi10). Homozygous hT2[bli-4 let-? qIs48] inviable. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype. Pick WT GFP and check for correct segregation of progeny to maintain. Reference: O'Hern PJ, et al. eLife 2017;6:e20752 doi: 10.7554/eLife.20752

Superficially wild-type with increased sensitivity to paraquat in multiple assays. Can be maintained 15-25C. rt451 is CRISPR/Cas9 engineered G85R missense mutation in endogenous sod-1 locus mimicking human ALS SOD1 model. Reference: Baskoylu SN, et al. PLoS Genet. 2018;14(10):e1007682. NOTE: A micropublication on these strains (PMID: 33474528) incorrectly described sod-1(rt448) as the G85R mutant version and sod-1(rt449) as the control. Additionally, the strains list in the paper also incorrectly describes rt449 as sod-1 [G85RC]. The correct descriptions are that rt448 is the wild-type control, rt449 is the sod-1 [G93AC] mutant version, and rt451 is the sod-1 [G85RC] mutant version.]

rtIs11 [osm-10p::GFP + osm-10p::HtnQ150 + dpy-20(+)]. osm-10 promoter drives expression of both GFP and Htn-Q150 strongly in ASH and more weakly in other neurons of the head and tail. pqe-1(rt13) accelerates Htn-Q150 induced toxicity resulting in ASH neuron cell death predominantly during larval stages. Hence, many adult animals will lack overt GFP expression in ASH neurons. rtEx377 in the original HA759 was selected against leaving only rtIs11 in the strain available at the CGC.

HG231 exhibits an approximately 20% increase in mean, median and maxium lifespans compared to N2. HG231 exhibits somewhat reduced fertility and somewhat longer development time than N2. It has a normal appearance, movements and mating behavior. It's swimming rate in liquid is slightly higher than N2. STS mapping indicates the most likely location for age-2 is on LG I.

This double mutant exhibits a doubling of both mean and maximum lifespans at 25C compared to N2. It exhibits a longer lifespan at 25C than it does at 20C. It has somewhat reduced fertility. It has normal development time, appearance, movements and feeding behavior. It's swimming rate in liquid is slightly higher than N2. STS mapping indicates the most likely location for age-2 is on LG I.
