[2/98: Craig Mello noticed a different embryonic phenotype in this strain as compared to the e2141 stock that Jim Priess obtained from England-the ABp fate appears WT.] [NOTE (11/16/10 - J. Hubbard): This strain is NOT synonymous with glp-1(e2144) as previously reported in Kodoyianni V, Maine EM, Kimble J. (1992) [Molecular basis of loss-of-function mutations in the glp-1 gene of Caenorhabditis elegans. Mol Biol Cell. 3,1199-213. PMID: 1457827]. As reported in Worm Breeders Gazette December 2010; 18(3), e2144 carries the mutation c2785t in exon 8, leading to the amino acid change L929F, whereas e2141 carries the mutations c2920t and a3610g in exon 8, leading to the amino acid changes R974C and T1204A.]

fib-1(mu498[wrmScarlet11::fib-1]) generated via CRISPR/Cas9 insertion into parental strain DUP237; transgene contains a linker between wrmScarlet11 and fib-1. Endogenous fib-1 detectable in the germline. T2A::wrmScarlet(1-10) fused to the C-terminus of endogenous GLH-1.
