arIs37 [myo-3p::ssGFP + dpy-20(+)] I. GFP is secreted from muscle cells. Do not distribute this strain; other labs should request it from the CGC.

ar200 does not display any apparent phenotype. It suppresses the Egl defect of both sel-12(ar171) and sel-12(ar131), and displays genetic interactions with various lin-12 and glp-1 alleles. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are WT and segregate WT, Uncs and Sterile Dpys which have an everted vulva. ar95 previously called evl-10(ar95). See also WBPaper00004382. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are WT and segregate WT, DpyUncs and Steriles which have an everted vulva. Segregates males, so may have a him- mutation? ar104 previously called evl-22 and mat-2. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are WT and segregate WT, Steriles with an Everted Vul and DpyUncs. Do not distribute this strain; other labs should request it from the CGC. ar105 previously called evl-5(ar105).

arIs41 [lin-12::GFP + rol-6(su1006)]. Rollers. Reference: Levitan D, Greenwald I. Development. 1998 Aug;125(16):3101-9. Do not distribute this strain; other labs should request it from the CGC.

At 15C a high percentage of hermaphrodites have a 0 AC-Egl phenotype. e1948 recessively suppresses vulval lineage defects and proximal mitosis. sc8 previously called rol-4(sc8). See also WBPaper00002448. Do not distribute this strain; other labs should request it from the CGC.

Worms are slow growing, with reduced brood size and become sterile at elevated temperatures. CED-1::GFP used to detect apoptotic cells in germline. Reference: Zeller P, et al. Nat Genet. 2016 Nov;48(11):1385-1395. doi: 10.1038/ng.3672. PMID: 27668659.

lsIs17 [pie-1p::GFP::pcn-1(W03D2.4) + unc-119(+)]. Worms are slow growing with reduced brood size and become sterile at elevated temperatures. Express GFP::PCN-1 in dividing cells of germline, embryos and larvae. Reference: Padeken J, et al. Genes Dev. 2019 Apr 1;33(7-8):436-451. PMID: 30804228

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.

rtEx726 [del-1p::YC2.60 + pha-1(+)] expresses yellow cameleon YC2.60 in a subset of motor neurons. Maintain at 25C to select for the presence of the array. Haspel G, et al. (2010) J. Neurosci. 30:11151-6.

Superficially wild-type. Reference: Anderson E, et al.Mech Ageing Dev. 2016 Mar;154:30-42.

rtSi1 [sod-1p::sod-1(WT) + Cbr-unc-119(+)] (inserted into cxTi10882) IV. Superficially wild-type. HA2619 serves as a control strain for HA2464. Reference: Baskoylu SN, et al. PLoS Genet. 2018;14(10):e1007682.

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. This is the appropriate control strain for FUS disease models HA2846 and HA2847. This control strain contains presumably silent edits inserted by CRISPR editing while creating the FUS disease models in HA2846 and HA2847, and was back-crossed to remove the pha-1 allele used in strain construction. Reference: Baskoylu S, et al. bioRxiv 799932; doi: https://doi.org/10.1101/799932

fust-1(rt256[R446S]) was created by CRISPR editing of arginine codon in C. elegans fust-1 to create FUS disease model for human mutation R524S. This strain also contains additional silent edits (also present in control strain HA2845), and was back-crossed to remove the pha-1 allele used in strain construction. Under normal culture conditions HA2846 animals are superficially wild-type; after stress latent defects are observed. Reference: Baskoylu S, et al. bioRxiv 799932; doi: https://doi.org/10.1101/799932

fust-1(rt257[P447L]) was created by CRISPR editing of proline codon in C. elegans fust-1 to create FUS disease model for human mutation P525L. This strain also contains additional silent edits (also present in control strain HA2845), and was back-crossed to remove the pha-1 allele used in strain construction. Under normal culture conditions HA2847 animals are superficially wild-type; after stress latent defects are observed. Reference: Baskoylu S, et al. bioRxiv 799932; doi: https://doi.org/10.1101/799932

Superficially wild-type at 25C. Can be maintained 15-25C, and latent defects observed after oxidative stress. rt451 was created by CRISPR editing of the cognate glycine codon in C. elegans sod-1 to create a disease model for human mutation SOD1 G85R. This strain contains additional silent edits in sod-1, and was back-crossed to remove the edited pha-1 allele used in strain construction. The appropriate control is HA2986. Reference: Baskoylu S, et al. PLOS Genetics (https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1007682). NOTE: A micropublication (PMID: 33474528) incorrectly described sod-1 alleles in the text. This strain contains rt451, which is sod-1[G85RC], while rt449 is sod-1[G93AC] and rt448 is the wild-type control for both.
