Heterozygotes are Unc. Segregates DpyUncs. Segregates Uncs which are recessive Mel. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

dnIs24 [sup46::flag::mCherry + Cbr-unc-119(+)]; site of integration unknown. Strong nuclear-localized mCherry.

Movement WT. Body muscle abnormal.

Dpy. Cold sensitive kinker Unc.

Heterozygotes are WT and segregate WT, Dpy Uncish with occasional Rol (nmy-1 dpy-8), Lon males, and dead eggs. nmy-1 homozygotes have a low brood size and are slow growing. sb115 is a null, truncation allele.

Segregates WT, males, Dpy, Rol, DpyRol, dead eggs (mcDf2). Use XX tra-2 males to move mcDf2 around. mcDf2 is an approx. 500 kb deficiency removing a large chunk between mec-2 and sup-7 (non-inclusive).

Heterozygotes are WT and segregate more WT, Dpys and dead eggs.

Maintain by picking semi-Dpy. Segregates semi-Dpy and Dpy.

FREE DUPLICATION. Segregates Dpy and semi-Dpy. Maintain by picking semi-Dpy.

Animals with mnDp30 are WT (slightly Dpy) and segregate WT (slightly Dpy) and dead eggs.

zuIs45 [nmy-2p::nmy-2::GFP + unc-119(+)] V. Temperature-sensitive maternal-effect lethal. Maintain at 15C. NMY-2::GFP is expressed in the germline and somatic gonad. Cross of JJ1473 and EU822. Unknown if unc-119(ed3) is still present or homozygous in background. NOTE: this strain was originally described as heterozygous for lin-2(e1309), but lin-2 has been lost; this strain is now homozygous wild-type for lin-2. Reference: Small LE & Dawes AT. Mol Biol Cell. 2017 Aug 1;28(16):2220-2231.

Unc. Suppressed by sup-5 and sup-7. Null allele? Milder than most null.

Temperature sensitive Unc.

Vulvaless. M-MATING++ 1-10%WT.

Strain is egg-laying defective. Homozygous mex-3(or20) is a non-conditional maternal effect lethal: worms fill up with dead eggs. Heterozygotes bag with 11/16 dead embryos and larvae. About 10% of worms can lay eggs and be mated into for outcrossing. The mex-3(or20) mutant embryos produce excess body wall muscle anteriorly.

or28 is a non-conditional maternal-effect embryonic lethal mutant ; the anterior pharynx is absent. and embryonic lethality is 100% penetrant. Pick single WT heterozygous hermaphrodites to maintain strain; these hets fill up with a mix of dead embryos and larvae [11/16 dead embryos due to aneuploidy from translocation segregation and lethal homozygous hT2; vulvaless due to homozygous lin-2(e1309) mutation; about 10% of lin-2(e1309) worms are leaky and lay eggs/can be mated into]. The homozygous or28 hermaphrodites fill up with dead embryos. The lin-2 background helps to score embryonic lethality for both heterozygotes and or28 homozygotes. or28 is a G to D mis-sense mutation at amino acid position 123.

The homozygous or28 hermaphrodites fill up with dead embryos. The lin-2 background helps to score embryonic lethality for both heterozygotes and or28 homozygotes. Strain produces a lot of males due to him-8(ec56). or28 is a G to D mis-sense mutation at amino acid position 123.

Maintain at 15C. Temperature-sensitive embryonic-lethal at restrictive temperature of 26C. Viable embryos at permissive temperature of 15C. Mitotic spindle in one-cell stage embryo assembles normally, but microtubules destabilize at anaphase and spindle becomes mis-positioned toward the posterior pole leading to highly abnormal cleavage and chromosome segregation defects.

hqIs180 [sdhb-1p::mtLS::cpYFP + rol-6(su1006)]. Rollers. About four mitoflash events per anterior pharynx per 200 seconds on adult days 2-3 when cultured on standard NGM plates at 20C. In hqIs180 mtLS is a mitochondrial localization sequence from SDHB-1 and cpYFP is circularly permuted yellow fluorescent protein, a superoxide sensor (Wang W. et al., Cell, 2008). The cpYFP signal is detected in most or all tissues, but most strongly in the pharyngeal muscles. Reference: Shen E-Z, et al. Nature. 2014 Feb 12. doi: 10.1038/nature13012.
