Weak allele of bar-1.

[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.

Unc. QL descendants in a mutant position (anterior of ALM). Okay to grow at 15 or 20C.

Egl. QL descendants in a mutant position (anterior of ALM). Okay to grow at 15 or 20C.

Hermaphrodites are sluggish and exhibit protruding vulva, ruptured vulva, or internally hatched progeny. Males move slower than WT and have disorganized tail rays.
