Temperature-sensitive embryonic lethal. Maintain at 15C. Reference: O'Rourke SM, et al. PLoS One. 2011 Mar 1;6(3):e16644.

[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.

Bacteria. E. coli HT115(DE3) bacterial strain carrying pGC8. pGC8 is a partial cDNA of him-14 (ZK1127.11) cloned into the Timmons and Fire "double T-7 vector" L4440. The source of the cDNA is Yuji Kohara's clone yk240h12. pGC8 was constructed by inserting the 1.65kb KpnI/SacI fragment of the him-14 cDNA (from base pair 1071 to 192 base pairs beyond the stop codon) into the same sites in L4440. HT115(DE3) carrying pGC8 should be selected in the presence of 50 um/ml tetracyline and 100 um/ml ampicillin. Prior to an actual feeding experiment, it can be grown in liquid in the presence of amp alone (no tet) and then seeded onto NGM plates containing amp and 1 mM IPTG. This technique does not work well if the cells are old; therefore, the strain should be seeded onto IPTG-containing plates from a fresh overnight that was grown from a colony on an amp/tet plate. Biosafety Level: BSL-1. For more info see http://www.wormbook.org/wli/wbg17.1p32/
