SSM474 C. elegans syp-4(iow90[GFP11::syp-4]) I; iowSi8 II; unc-119(ed3) III. Show Description
syp-4(iow90[GFP11::syp-4]) I. iowSi8[pie-1p::GFP(1-10)::him-3 3UTR + Cbr-unc119(+)] II. CRISPR/Cas9 insertion of GFP11 tag into endogenous syp-4 locus in background strain SSM471. GFP::SYP-4 fluorescence only observed in the germline. If germline silencing occurs, transgene expression can be recovered by growing worms at 25C for 2 generations. Reference: Hefel A & Smolikove S. G3. 2019 Jun 5;9(6):1933-1943. PMID: 30992318.
CV87 C. elegans syp-4(tm2713) I/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III). Show Description
Homozygous lethal allele balanced by bli-4- and GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP syp-4(tm2713) homozygotes (viable but throw 97% dead eggs, 40% males). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. Reference: Smolikove S, et al. (2009) PLoS Genet 5(10):e1000669.
