ok98/+ animals are slightly Egl-d and have a small vulval bump. ok98 homozygotes are straight and paralyzed and slow growing. About 2/3 eventually reach adulthood and are paralyzed and sterile (they produce few if any oocytes). Segregates Unc Muv(ts).

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.

Null or nearly null allele. Sluggish locomotion. Slightly short. Egl. Growth rate ~72% of wild-type. Reference: Edwards SL, et al. Genetics May 2013 194:143-161. (See Commentary in same issue 194:35-37).

ceIs56 [unc-129p::ctns-1::mCherry + nlp-21p::Venus + ttx-3p::RFP]; Maps to X: 9.0 +/ 3.0 m.u. Expresses the lysosomal membrane marker CTNS-1 in a subset of 9 DA/DB cholinergic motor neurons in the ventral cord, and NLP-21::Venus in the same neurons as a marker for soluble DCV cargo and to help identify the boundaries of the somas and axons when imaging lysosomes.

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.

ceIs201 [unc-17p::ins-22::Venus + unc-17p::RFP + unc-17p::ssmCherry + myo-2p::RFP]; integration site maps to I:0.77. Expresses INS-22::Venus to mark Dense Core Vesicles in the cholinergic nervous system, including the ventral cord cholinergic motor neurons. Also expresses mCherry in the same neurons to help identify the boundaries of the somas, axons, and dendrites. ssmCherry is mCherry with a secretion signal on its N-terminus, which is constitutively secreted and taken up by coelomoctyes in the pseuodcoelomic space, making it a useful marker for those coelomocytes. The INS-22::Venus also gets secreted by DCVs and taken up by coelomocytes. The myo-2::RFP is a co-tranformation marker that lights up the pharyngeal muscle cells and is useful for crossing the integrant into various mutant backgrounds. Reference: Hoover CM, et al. Genetics. 2014 Mar;196(3):745-65.

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.
