sos-1 gain-of-function allele originally isolated as a suppressor of sem-5(n1619) lethality. pd10 causes a E99K substitution within the N-terminal histone fold domain of SOS-1. Single mutants appear wild-type.

CGC1 (formerly known as PD1074) is intended to be used as a wild-type reference strain with the closely matched genome assembly of Yoshimura, et al. (Genome Res. 2019 Jun;29(6):1009-1022) available on Wormbase as VC2010-1.0. (ENA study accession PRJEB28388; assembly accession GCA_900538205). CGC1 is a defined and recently cloned population of animals derived from the original "Bristol" variant of C. elegans originally obtained by Brenner from E. Dougherty with no known history of mutagenesis. Brenner's original population, called N2, was used as the basis for the vast majority of laboratory strains in use currently. No early frozen stock of the unmutagenized N2 population currently exists, but later stocks were available from several laboratories. CGC1 is a clonal population founded by picking a single worm of one such stock, VC3510. VC3510 in turn derives from a subpopulation of N2 described in the literature as VC2010. We note that CGC1 is expected to be largely similar to most lab N2 strains, but that as a clonal isolate derived from N2, there will be some loci that will vary compared to any other particular N2 isolate. One such example is a partial deletion of the alh-2 locus in CGC1. Additional loci that were found to vary between the prior N2 reference genome (WormBase release WS264) and the VC2010-1.0 assembly are detailed in supplemental table 8 in Yoshimura, et al, (2019).

qaIs8400 [let-858p::Ov-GST-3 + rol-6(su1006)]. Called AK1 in the reference article. The Ov-GST-3 gene was amplified from genomic DNA of O. volvulus with 1µM of the sequence specific primer 5'Klon and 3'Klon (5'Klon: 5'-GGCGTACGATGTCAAGATTTCCTCAACAAG-3'; 3'Klon: 5'-GGTCTAGATTTATTTAGGAATGATTGAATCGGTCG-3'; representing bases 4 - 25 and the complementary sequence of bases 821 - 841 of the published Ov-GST-3 cDNA (AF203814); bold underlines indicate restriction sites for Pfl23II (SplI) and XbaI, respectively; dotted underline indicates the start codon for translation; italics indicates the conserved sequence for the polyadenylation signal for transgenic transcript processing; the 8 5'-nucleotides of primer 3'Klon and the fourteen 5'-nucleotides of primer 5'Klon do not correspond to the template and introduce the sequences to the amplicon), 200 µM of each deoxynucleotide (Gibco BRL) and 2.5 units of Taq polymerase (Gibco BRL). After an initial denaturation of 3 minutes at 93°C, 35 cycles of annealing at 55°C for 1 minute, synthesis at 72°C for 2 minutes and a 1 minute denaturation at 93°C were performed, followed by a final extension at 72°C for 5 minutes. The genomic Ov-GST-3 fragment obtained by PCR (see above) was ligated into the pGEM-T Easy vector (Promega) by TA-cloning, cleaved with the restriction enzymes Pfl23II (SplI) and XbaI (restriction sites introduced by the primer) and inserted between the unique Pfl23II (SplI) and XbaI sites of the vector pPD103.05 (kindly provided by A. Fire). The sequence of the genomic Ov-GST-3 fragment in the resulting plasmid pAK1 was confirmed by automated dye terminator, dideoxy sequencing (ABI Prism 377TM Sequencer, PE Applied Biosystems) using the PCR primers (see above). The pAK1 DNA was injected in combination with the marker plasmid pRF4 [rol-6(su1006)] into the gonads of N2 C. elegans at a concentration of approximately 100 ng/µl for each plasmid. Transgenic worms were identified by the selectable Roller marker phenotype and the stable transmitting line AK1ex (AK1 extrachromosomal) was established. Integration of the extrachromosomal arrays was achieved by irradiation of AK1ex worms with 3600 rad (1 rad = 0.01 Gy) of x-rays (x-ray chamber: RUM 9421-070-77002, Philips, Netherlands; dosimeter: PTW-SN4, PTW, Germany). The progeny of these worms was then screened for 100% transmittance of the Roller phenotype to obtain the C. elegans line AK1int (AK1 integrated) with the chromosomally integrated transgenes.
