BRC546 C. elegans antIs30 II; unc-119(ed9) III. Show Description
antIs30 [attP-f + Cbr-unc-119(+) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. antIs30 was inserted into ttTi5605 on LG II using MosSCI. GFP expression in pharynx is very weak (as it is single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. Reference: Yang FJ, et al. "phiC31 integrase for recombination mediated single copy insertion and genome manipulation in C. elegans." Genetics 2021.
BRC566 C. elegans antIs31 II; unc-119(ed9) III. Show Description
antIs31 [attP-f + Cbr-unc-119(ant40) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. Unc. antIS31 has been found to self-excise; check for GFP expression periodically to retain the insertion. GFP expression in pharynx is very weak (as it is in single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. antIs31 was derived by CRISPR/Cas9 knockout of Cbr-unc-119 in antIs30 creating ant40, a 691 bp deletion in Cbr-unc-119. Because antIs31 does not rescue unc-119(ed3), BRC566 facilitates the use of Unc-119 rescue as a selection marker for transgene insertions. Reference: Yang FJ, et al.

Strain shows deficits in chemotaxis, associative learning, and thrashing in liquid. Strain also has incomplete sterility due to germline proliferation defects and embryonic lethality.

DR1942 C. elegans daf-2(e979) III. Show Description
This strain forms 20% dauers at 15C. At 25C there occurs about 25% embryonic arrest and about 75% L1 arrest. The e979 mutation results in an amino acid substitution, C146Y, in the ligand-binding domain of the DAF-2 receptor. [CGC received new stock of DR1942 September 2002. Previous stock was probably m41 and not e979.] [June 2004: Patrice Albert has confirmed the mutation in this stock: Repeat of sequencing for CGC collection strain DR1942 [daf-2(e979)] is complete. The strain does carry a C146Y mutation (coding strand TGC to TAC) [Mutation position is at 143, not 146, based on the amino acid sequence shown in Wormbase for daf-2. It's the C in partial sequence EKRCGPI of Exon 5.].]

FK163 C. elegans cam-1(ks52) II. Show Description

FK171 C. elegans mek-1(ks54) sek-1(qd127) X. Show Description
Hypersensitive to copper and cadmium ions, and to starvation. [NOTE: Prior studies suggested possible cross-regulation of PMK-1 by MEK-1, but the identification of a tightly linked partial loss-of-function mutation in sek-1(qd127) in the strain carrying the mek-1(ks54) mutant allele (K. Reddy and D. Kim, unpublished data) suggests that the diminished PMK-1 activation observed in this mutant strain may actually be due to diminished SEK-1 activity.]
GC363 Escherichia coli E. coli. Show Description
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/

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

Temperature sensitive Daf-c; heh-1 animals more readily form dauers at 27C than WT animals. Partial dauer phenotype; dauers exhibit ale but do not fully constrict pharynges nor arrest germline proliferation.
