Defective response to short wavelength light; response strongly reduced but not eliminated. All other characteristics seem wild type, including reponse to mechanosensory stimuli. Strong, probably null, allele. This mutation also blocks the coordinated light response of unc-31(e928) and egl-30(ad805). To identify lite-1 homozygous mutants when crossing into different backgrounds, use a fluorescence stereomicroscope with a GFP filter and zoom to the hightest magnification (60-100X) to distinguish Lite from non-Lite animals. This works best when the animals are mired in thicker parts of the food to slow their spontaneous locomotion but not their response to light. Scan animals around the edge of the food where it is thickest. Leave the lid of the plate off for a minute or so before starting to let the animals adjust to air currents.

Coordinated hyperactive locomotion. Hypersensitive to mechanical stimuli. Most mature adults have vulval bump. Mature animals are slightly short and egl-d. Terminal phenotype is usually bag of worms. Population tends to severely crash within 2-3 weeks of starvation. Dominant, gain-of-function allele. Heterozygotes are difficult to distinguish from homozygotes. Mutation is R182C. This same mutation causes constitutive Gs activity in vertebrates. Sequence in WT: CCT TCG GTG TCG. Sequence in ce81: CCT TCG GTG TTG.

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.

Lox P sites in 3' UTR and 4th intron flank kinesin motor domain sequences; sup-1(e995) mini-gene inserted in second intron. Appears wild-type on plates and in quantitative locomotion assays. Can be used to conditionally delete gene sequences encoding the conventional kinesin motor domain in a tissue specific manner by driving expression of Cre recombinase in the tissue of interest.

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.

About normal size and distribution on food. Hyperactive locomotion. Hypersensitive to stimuli. Most mature adults have slight vulval bump. Not obviously Egl-d or Egl-c. Dominant, gain-of-function allele. Mutation is P260S. Sequence in WT: CAGTCTGTGATG C CT. Sequence in ce2: CAGTCTGTGATG T CT.

About normal size. Hyperactive locomotion. Hypersensitive to stimuli. Most mature adults have slight vulval bump. Not obviously Egl-d or Egl-c. Dominant, gain-of-function allele. Mutation is A337T. Sequence in WT: TAAATCT G CCGACG. Sequence in md1756: TAAATCT A CCGACG.

Short. Relatively constant motion (coordinated hyperactivity). Adults quickly become Egl-d and most have vulval bump. Hypersensitive to stimuli. Loopy backing, but does not like to back, especially after repeated stimuli. Terminal phenotype is usually bag of worms. Population tends to severely crash after 2-3 weeks of starvation. Dominant, gain-of-function allele. Heterozygotes are also hyperactive and difficult to tell apart from homozygotes. Mutation is G45R. Sequence in WT: GGC GCC G GA GAG AGC. Sequence in ce94: GGC GCC A GA GAG AGC.

Adults generally short, although some can reach near normal length. Slow growth rate. Backing can be loopy, but does not like to back. Strongly hypersensitive to stimuli. Relatively constant spontaneous movement. Some clustering especially in response to stimuli. Mature adults have vulval bump. Most young adults are Egl-c and young embryos can be found on the plate. Some mature adults become moderately Egl-d. Recessive allele. Males are small and slow growing. Mutation is R92C, which is a conserved residue in the 10 amino acid inhibitory domain that normally functions to keep protein kinase A turned off in the absence of cAMP. Population tends to severely crash within 2-3 weeks of starvation.

Hyperactive locomotion and hypersensitive to stimuli such as plate dropping. Restores wild type levels of locomotion to paralyzed ric-8(md303) mutants. Most, but not all adults, appear significantly Egl-c. Some mature adults are thinner than normal. Aldicarb sensitivity, growth rate, pumping, length, and distribution on food are all similar to wild type. The ce268 mutation is a D448N change relative to PDE-4D isoform. It disrupts the catalytic domain by changing one of the four active site residues that together chelate an active site zinc atom. Inheritance is semi-dominant due to dominant negative side effects.

Animals with the Duplication are WT. Animals which have lost the Duplication are Lon and throw dead eggs.

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).

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.

tm1095 enhances Q neuroblast migration and vulva induction phenotype of pry-1. Minor defect in excretory cell development. Reference: Oosterveen et al. (2007) Dev Biol 308: 438-48.

No obvious phenotype on its own. Suppresses cell swelling and death caused by expression of a GTPase defective Gxs subunit expressed from the glr-1 promoter, semi-dominant. Strongest allele.

Slow-growing wild-type, Him. Segregates WT, DpyUnc, WT males and dead eggs (hDf8 homozygotes). Heterozygotes also exhibit low-penetrance vulval blips; these may be more pronounced, present at higher frequency and accompanied at times by tail blips upon recovery from starvation. hDf8 dominantly suppresses recombination from around unc-13 at least to dpy-5, and possibly to the left end of chromosome I. Maintain by picking WT and checking for correct segregation of progeny.
