Homozygous or195 hermaphrodites make 100% dead embryos at 26C. One-cell embryo has a very small but bipolar spindle, severe chromosome segregation defect. Maintain at 15C. Previously called spd-4. 2/06: From Bruce Bowerman: The or195 mutation changes base 10,679 of the cosmid clone T21E12 from a C to a T. This corresponds to dhc-1 cDNA nucleotide 9599 (WS153) , which is the center nucleotide of codon 3200. This codon changes from Serine in N2 to Leucine in or195 (S3200L). Note: this is not the same mutation for or195ts that we reported in Hamill et al, 2002(Dev Cell 3, 673-684). The mutation reported in our paper is not present in this strain. We apologize for the confusion. The pairs dhc-11a,b amplify the mutated fragment in dhc-1(or195). The mutation is near the center of this fragment; a clean (gel purified) DNA prep helps get a good read of it. dhc-11b: 5' aacagacgcacgattgacct 3'. dhc-11a: 5' ctcaaatcaaggaaggagct 3'. PCR conditions: 5 min at 94 degrees C; 30 sec at 94 degrees C; 30 sec at 55 degrees C; 1 min at 72 degrees C. 35 Cycles using Taq polymerase.

Conditional, semi-dominant, maternal-effect, embryonic-lethal mutation. Once-cell stage mitotic embryos have short astral microtubules and a mispositioned mitotic spindle. Maintain at 15C.

Homozygous mutant animals give rise to >99% dead embyros at the restrictive temperature of 26C, with embryos exhibiting a lack of pronuclear migration at the one-cell stage. Homozygous mutant animals give rise to viable progeny at the permissive temperature of 15C. Maintain at 15C.

[NOTE: (10/22/2020) This strain also carries a (T to A) missense mutation in pry-1 which results in a PRY-1 N354K amino acid substitution.] bar-1(ga80) hermaphrodites are usually Egl and often have a protruding vulva (Pvl), although approx. 40% of animals appear WT on plates. Also slightly Unc. In bar-1(ga80) hermaphrodites any of the six vulval precursor cells (P3.p - P8.p) can sometimes fuse with hyp7 without dividing, and P5.p - P7.p can adopt the tertiary cell fate instead of the primary or secondary fates. In addition, the neuroblast QL and its progeny migrate towards the anterior instead of the posterior, and the cell P12 usually adopts the fate of P11. bar-1(ga80) do mate, but poorly. bar-1 encodes a beta-catenin molecule and the ga80 mutation is predicted to cause an early truncation of the protein.

Superficially wild-type. Null mutation: premature STOP codon and frame shift. Reference: Delaney K, et al. Genetics. 2018 Apr 10. pii: genetics.300909.2018. doi: 10.1534/genetics.118.300909. [Epub ahead of print].

Hypomorphic allele. Fully viable and fertile. Strongly uncoordinated larvae, tend to coil backward. Dpyish, mildly Unc adults. Isolated out of a mutator strain also containing uncharacterized e2281 and e2282.

cdk-5(gm336) mutants exhibit defects in polarized trafficking of dense-core vesicles in motor neurons, and decreased localization of GLR-1::GFP to puncta in ventral nerve cord interneurons. Note that this strain does not contain GLR-1::GFP. References: Juo P, et al. Mol Biol Cell. 2007 Oct;18(10):3883-93. Goodwin PR, et al. J Neurosci. 2012 Jun 13;32(24):8158-72.

Hypersensitive to copper and cadmium ions, and to starvation. [NOTE: Prior studies suggested possible cross-regulation of PMK-1 by MEK-1, but the identification of a tightly linked partial loss-of-function mutation in sek-1(qd127) in the strain carrying the mek-1(ks54) mutant allele (K. Reddy and D. Kim, unpublished data) suggests that the diminished PMK-1 activation observed in this mutant strain may actually be due to diminished SEK-1 activity.]

Made by crossing MT3353 egl-15(n484) sma-5(n678) with N2 males and selecting animals that grew much better. FK312 probably only carries the sma-5(n678) mutation but that has not been confirmed by sequencing. Small body size, slow growth, abnormal intestinal granules, shorter lifespan than WT.

Rollers express mutated HMR-1 intracellular domain (unable to bind catenins) pan-cortically in cells upon heat shock. Maintain at 15C or 20C to prevent leaky expression of heat shock transgene.
