Heterozygotes are WT and segregate WT, Dpy Unc-4, and Unc-104s.

Temperature sensitive. Maintain at 15C. Animals grown at 14C take 23% longer than wild-type to reach adulthood, exhibit 0% larval arrest, locomotion rates that are ~40% of wild type, and synaptic vesicle densities at synapses that are ~60% of wild type. Animals grown at 20C take 80% longer than wild type to reach adulthood, exhibit locomotion rates that are ~3% of wild type, and synaptic vesicle densities at synapses that are ~2% of wild type. Animals grown at 25C exhibit >90% larval arrest. When shifting late larval stage and adult animals from 14C to 25C, it takes 8-12 hours to see effects on locomotion and SV density.

The Auxin Inducible Degron (AID*) flanked by a 5X Myc/spacer tag on left and a single spacer on the right is fused to the N-terminus of the unc-104 gene. Allows conditional degradation of UNC-104 protein when combined with tissue specific expression of TIR1 in the presence of 1 mM Auxin in plate media. Note: KG5148 does not express TIR1. On standard plates: wild type growth, appearance, and locomotion rate. For animals expressing a TIR1 transgene in the nervous system: Animals that hatch and develop on 1 mM Auxin plates generally remain tightly coiled near the location of hatching and exhibit slow growth (up to 7 days to reach adulthood, with 98% reaching adulthood by 7 days). Adults placed on Auxin abruptly lose about 75% of their locomotion function between 6 and 12 hours after plating. The remaining locomotion function is lost gradually between 12 and 52 hours.

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.

Heterozygotes are WT and segregate WT, Uncs and dead eggs and larvae with severe body morphology defects that do not develop beyond the L2 stage. A few very rare mc44 larvae reach adulthood but they become sterile. mc 44 is a deletion affecting the downstream transcription unit of vab-10 named vab-10b. Fails to complement the vab-10 null reference allele vab-10(h1356), but complements the vab-10a alleles vab-10a(e698) and vab-10a(ju281).

Heterozygotes are WT and segregate WT, Uncs, and severely Lumpy arrested L1s (ok817). m1 can easily get lost through recombination.

Heterozygotes are GFP+ wild type and segregate GFP+ Unc, GFP+ wild type, and GFP- sptf-3 homozygotes. nIs425 was integrated into sptf-3(tm607)/hIn1[unc-101(sy241)] I. The position of integration appears to be close to or lie within the region covered by hIn1: sptf-3(tm607) heterozygotes are GFP+ whereas sptf-3(tm607) homozygotes do not express GFP in the pharynx.
