mel-8 is a maternal effect lethal. WT heterozygotes (sc13 recessive) segregate WT, MelUncSqt (sick and small), mnC1 dpy-10 unc-52 homozygotes (paralyzed Dpys). Rescued by male mating.

Temperature sensitive-grow at 15C. Par at 25C. Strict maternal effect lethal.

Superficially wild-type. Note that double homozygous mutants of pkc-3(it309) with par-2(it315) exhibited partially penetrant and variable maternal effect lethality and maternal effect sterility that was stronger than it315 alone. Thus, although the GFP tag on pkc-3 shows no effect in an otherwise wild-type background, it does seem to somewhat compromise the activity of the protein it tags. Made in N2 background.

par-2(it315) exhibits a weak maternal effect sterility, suggesting that the tag reduces the protein activity. Note, however, that double homozygous mutants of it315 with pkc-3(it309) or par-6(it310) exhibited partially penetrant and variable maternal effect lethality and maternal effect sterility that was stronger than it315 alone. Thus, although the GFP tags on pkc-3 and par-6 show no effect in an otherwise wild-type background, they do seem to somewhat compromise the activity of the proteins they tag. Made in N2 background.

Maternal effect lethal mutation. Temperature sensitive-grow at 15C. Some growth at 20C. Does not grow at 25C. Rescued by male mating.

Strict maternal effect lethal. Temperature sensitive-grow at 15C. Par at 20C and 25C.

Temperature-sensitive maternal effect lethal (strict). Maintain at 15-16C (95% of embyros hatch). Shift to 25C for Par phenotype (no hatching embryos).

Maternal effect lethal mutation. High incidence of males in surviving offspring. Not rescued by male mating. Temperature sensitive.

mel-8 is a maternal effect lethal. WT heterozygotes segregate WT; mel-8 unc-4 homozygotes that lay eggs that don't hatch, and mnC1 dpy-10 unc-52 homozygotes (paralyzed Dpys). Some F2 mel homozygotes hatch, but such escapers arrest at L1 or L2. Previously called mel-6(it27).

Heterozygotes are WT and segregate WT, DpyUncs and Sterile Uncs. it145 is a recessive mutation that results in multiple rows of small oocytes instead of a single row of normal size oocytes. it145 is a recessive maternal effect lethal mutation: hermaphrodites produce embryos that fail to hatch - the embryos exhibit a partial defect in P0 nuclear rotation and a strong defect in P1 nuclear rotation; PAR proteins are mislocalized in P1.

Heterozygotes are WT and segregate WT, paralyzed Unc, and Coilers which give only dead eggs (slightly leaky, but survivors are agametic). zu222 is a strict maternal effect embryonic lethal. Partitioning defect similar to that of par-3; fails to localize PAR-3 protein.

Temperature-sensitive maternal effect lethal. Maintain at 15C. At 25C embryos show polarity defects and fail to hatch. Reference: Morton DG, Hoose WA, Kemphues KJ. Genetics. 2012 Aug 10.

mix-1(b285) is maternal effect lethal. Heterozygotes are WT and segregate WT, Unc-4 worms which are strong Egl, and paralyzed Dpy Uncs.

Slightly short and fat as adults. 1376 bp deletion of part of intron 1 through intron 4. Contains an integrated hlh-8::GFP reporter marking the postembryonic M lineage.

760 bp deletion beginnin in exon 3 and ending in exon 4. No strong visible phenotype.

745 bp deletion of cdk-4 from intron I to exon3 removing putative ATP binding domain and catalytic residues. Most homozygous animals arrest at L2 due to absence of most or all postembryonic somatic cell divisions. Some germline proliferation resulting in slightly elongated gonad.

huIs120 [hsp-16.2p::sfrp-1 + myo-2p::Tomato]. Wild-type under normal culture conditions. Heat-shock (10 min) during embryogenesis causes embryonic lethality and HSN migration defects. Heat-shock (10 min) at hatching causes Ql and QR migration defects. Reference: Harterink M, et al. Development. 2011 Jul;138(14):2915-24.

sf1003 is a CRISPR-engineered deletion in aat-1. aat-1(sf1003) mutants show elevated pumping rates and enhanced learning capacity compared to well-fed wild type animals (similar to nkat-1 mutants). Reference: Lin L, et al. Genes Dev. 2020 Aug 1;34(15-16):1033-1038. doi: 10.1101/gad.339119.120. PMID: 32675325.

kasEx80 [oig-1p::tagRFP::unc-54 3'UTR + pha-1(+)]. Maintain at 25C to maintain array. RFP driven by minimal oig-1 promoter for expression in VD-type GABAergic motor neurons. This construct uses the minimal length of promoter containing overlapping LIN-39 and UNC-30 ChIp-seq peaks (deletion of the single LIN-39 binding site within it compromised GABAergic motor neuron expression). Whereas other available oig-1 constructs are expressed ectopically in cholinergic motor neurons in unc-3 mutants, expression of this construct remains exclusively in GABAergic motor neurons. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx73 [unc-3p::dsUnc-3(RNAi) + myo-2p::GFP]. Pick GFP+ to maintain array. Array carries a construct with the unc-3 promoter driving transcription of a hairpin targeting unc-3 for RNAi depletion in cholinergic motor neurons. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx149 [oig-1p(2.6kb_del)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 2.6kb cis-regulatory region with 200bp deletion removing predicted LIN-39 binding site upstream of oig-1 was fused to GFP. Expression of oig-1::GFP in GABAergic motor neurons is been abolished; expression was observed specifically in cholinergic motor neurons of the ventral nerve cord. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx151 [oig-1p(2.6kb_del)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 2.6kb cis-regulatory region with 300bp deletion removing predicted LIN-39 binding site upstream of oig-1 was fused to GFP. Expression of oig-1::GFP in GABAergic motor neurons is retained, but eliminates ectopic expression in cholinergic motor neurons of the ventral nerve cord. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.
