KG421 C. elegans gsa-1(ce81) I. Show Description
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.
KG4386 C. elegans unc-104(ce782) II. Show Description
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. Reference: Edwards SL, et el. Genetics. 2015 Sept 201(1): 91-116.
KG524 C. elegans gsa-1(ce94) I. Show Description
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.
KG744 C. elegans pde-4(ce268) II. Show Description
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.
KK1228 C. elegans pkc-3(it309[GFP::pkc-3]) II. Show Description
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.
KK1254 C. elegans par-2(it315[mCherry::par-2]) III. Show Description
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.
KK725 C. elegans nop-1(it142) III. Show Description
Recessive maternal effect. Embryos from nop-1 mothers exhibit no pseudocleavage contractions or furrow. The majority of the embryos survive and grow into fertile adults.
KK822 C. elegans par-1(zu310) V. Show Description

KN1510 C. elegans huIs120. Show Description
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.
KP1287 C. elegans nuIs26 IV. Show Description
nuIs26 [cat-1::GFP] IV. nuIs26 contains a full length CAT-1::GFP fusion protein (with GFP fused at the predicted carboxy terminus of CAT-1). This transgene rescues the hyperactive locomotion defect of cat-1(e1111). This strain is slightly sluggish for locomotion and has a high degree of sterility (80%), both of which appear to be associated with the transgene. GFP expression in this strain is similar to the CAT expression pattern described by Duerr et al (1999) J Neurosci 19: 72-84.
KQ2841 C. elegans aat-1(ft1003) IV. Show Description

Reference: Lin L, et al. Genes Dev. 2020 Aug 1;34(15-16):1033-1038. doi: 10.1101/gad.339119.120. PMID: 32675325.
KR2365 C. elegans unc-11(e47) I; hEx16. Show Description

Homozygous ifg-1::mos yields only 444 bp product. Outcrossed heterozygotes yield both 353 bp (wild type ifg-1) and 444 bp products.
KX84 C. elegans ced-3(n2452) IV; bcIs39 V. Show Description
bcIs39 [lim-7p::ced-1::GFP and lin-15(+)] V.  Resistant to germ cell apoptosis.

LE6897 C. elegans src-1(syb7248)/tmC20 [unc-14(tmIs1219) dpy-5(tm9715)] I; juIs76 II. Show Description

Heterozygotes are wild-type with Venus+ pharynx, and will segregate wild-type with Venus+ pharynx (heterozygotes), embryonic lethality (syb7248 homozygotes), and Dpy with Venus+ pharynx (tmC20 homozygotes).

LV18 C. elegans unc-45(wc1) dpy-1(e1)/daf-7(e1372) par-2(it46) III. Show Description
Maintain at 25C. At 25C, heterozygotes are WT and segregate WT, Dauers (dauer escapers will be Par and give only dead eggs), and DpyUcs which arrest as dead eggs (range from twitching multicellulars to 3-folds that hatch). [There is a greater percentage of hatchlings when the mother is heterozygous (wc1 dpy-1/+). There may also be the possibility of near complete maternal rescue (near full-sized, sterile Dpys), but this has not been routinely observed in the balanced strain (as opposed to wc1 dpy-1/+).] Maintain by picking WT at 25C and scoring for correct segregation of progeny. [3/97: The dauers are not giving dead eggs-they are giving other dauers. Appears that the Par mutation is no longer present.]
LV19 C. elegans unc-45(wc2) dpy-1(e1)/daf-7(e1372) par-2(it46) III. Show Description
Maintain at 25C. At 25C, heterozygotes are WT and segregate WT, Dauers (escapers will be Par and give only dead eggs) and DpyUncs which are dead eggs (a range of embryonic lethality from multicellular twitchers to 3-folds that do not hatch). Maintain by picking WT at 25C and scoring for correct segregation of progeny. [3/97: the dauers are giving dead eggs.]
