N-terminal tag of CCDC-47 via CRISPR/Cas9 knock-in of mNeonGreen at ccdc-47 locus. Insertion verified by PCR, Sanger sequencing, and fluorescence. Left flank: 5' gttaaatcactcaatttcgggtcgttcacc 3'; Right flank: 5' ATGAAGATAGTATGGATTTTCCTAATATTC 3' (3 silent mutations); sgRNA: cgttcaccATGAAAATCGTC; Cas9/sgRNA plasmid: pGLOW13; mNG^SEC^3xFlag plasmid: pGLOW17; SEC insertion allele strain (balanced): GLW38.

Temperature sensitive. At 22.5C, maternal effect embryonic lethal. Temperature shift-up to 22.5C during embryogenesis results in animals with Egl, Pvul and Psa (phasmid socket absent) phenotypes. Shift-up to 25C results in growth arrest at larval stage. The T cell division can be symmetric as in lin-17 mutants. At 15C, nearly WT. Males grown at 15C can mate very well. psa-1 encodes a homolog of yeast SW13, a component of the SWI/SNF complex. Sequence data of this strain revealed the mutation is actually GTC/CCC/TCA to GTC/CTC/TCA causing a P86L substitution (G. Hayes).

pkIs2386 [unc-54p::alpha-synnuclein::YFP + unc-119(+)].

Endogenous tni-3 locus tagged with mCherry using CRISPR/Cas9. GFP-nls coexpressed from the endogenous promoter using SL2 trans-splicing. Visible using fluorescent dissecting microscopes. WT movement and behavior. Please contact Ryan Littlefield prior to publishing work using this strain.

GFP tag inserted in endogenous unc-94 locus; specifically tags UNC-94A isoform. mCherry tag inserted into endogenous tni-3 locus; GFP::NLS coexpressed from the endogenous tni-3 promoter via SL2 trans-splicing. GFP::UNC-94 is visible by compound microscopy as striations in body wall muscles, as elongated puncta in single-sarcomere (anal depressor, uterine, and vulval) muscles, as well as the cell bodies of two neurons. GFP::UNC-94 is not visible on fluorescent dissection microscopes. Please contact Ryan Littlefield prior to publishing work using this strain.

Animals with the duplication are WT. Animals without the duplication are Nob (NO Back end; 100% lethal). Pick wild-type to maintain; typically segregates about 50% wild type progeny and 50% Nob larvae.

Heterozygotes are WT and segregate WT, DpySteriles and dead eggs. Maintain by picking WT.

gwIs39 [baf-1::gfp-lacI::let-858 3'UTR + vit-5::GFP] III. bqSi225 [emr-1p::emr-1::mCherry + unc-119(+)] IV. gwIs59 [pha-4::mCherry::256xLacO::4xLexA + unc-119(+)]. Superficially wild-type. Express ubiquitous EMR-1::mCherry at the nuclear periphery. Expresses GFP-LacI from early embryogenesis and throughout development, which forms a small spot at the lacO array. Worms have red intestine (all stages) and green intestine (from late L4 stage). Reference: Harr JC, et al. Genes Dev. 2020 Apr 1;34(7-8):560-579. PMID: 32139421.

Egg-laying (Egl) defects and subsequent internal hatching of progeny (Bagging) in > 95% of animals. xe11 is a C-to-U point mutation in each of the endogenous let-7 complementary sites, LCS1 and LCS2 [I:C9,335,211T & I:C9,335,260T]. xe11 is a weak gain-of-function allele: mutation of two functionally relevant let-7 binding sites impairs repression by let-7 causing over-expression of LIN-41 in L4 stage animals. Reference: Ecsedi M, et al. Dev Cell. 2015 Feb 9;32(3):335-44. Do not distribute this strain; other labs should request it directly from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

General chemical hypersensitivity (including bleach), fragile cuticle. Derived by outcrossing CB7014 five times to N2. [NOTE: the e3016 mutation is TGG>TGA but it affects codon W124, not W130.] Reference: Loer CM, et al. Genetics. 2015 May;200(1):237-53.

Abnormal distal tip cell migration detectable as clear patches in anterior and posterior. Partially penetrant embryonic arrest and early larval lethal.

Heterozygotes have Unc-24 phenotype and segregate additional hets, embryonic lethals (stDf7/stDf7) and Unc females (or sometimes hermaphrodites) that Twitch.

At 20C heterozygotes are WT and segregate WT, Uncs and PATs. st430 is a recessive lethal causing "mild" PAT phenotype. unc-45 is temperature sensitive (WT at 15C).

Segregates heterozygotes that display only the unc-82 phenotype: slow but normal movement, disorganized muscle structure, somewhat Egl. stDf7 homozygotes die as embyros. unc-44 unc-82 homozygotes generally die as coiled, poorly-moving larvae.

Heterozygotes are Unc non-Dpy and segregate Unc non-Dpy, DpyUnc and PATs. st568 is a recessive lethal causing a PAT phenotype (paralyzed embryoes, arrested elongation at 2-fold length).

Animals with the duplication are WT and segregate WT, sterile and Pats. Strain can be propagated by chunking.
