Worms are slow growing, with reduced brood size and become sterile at elevated temperatures. met-2 and set-25 mutants co-segregate with ~ 20cM distance. Express GFP::H2B in germline and early embryos. Might still carry unc-119(ed3) in background. Reference: Zeller P, et al. Nat Genet. 2016 Nov;48(11):1385-1395. doi: 10.1038/ng.3672. PMID: 27668659.

Pick GFP+, Egl to maintain. Segregates GFP- lin-41(xe8) homozygotes (die by vulval bursting as young adults), lin-41(xe8)/lin-41(bch28[eft-3p::gfp::h2b::tbb-2 3'UTR] xe70) heterozygotes (GFP+, Egl), and lin-41(bch28[eft-3p::gfp::h2b::tbb-2 3'UTR] xe70) (GFP+, Ste, Dpy). lin-41(xe8) is a deletion of let-7 binding sites in the lin-41 3'UTR. The balancer was derived from lin-41(bch28), a lin-41(0) allele in which an expression cassette that drives ubiquitous nuclear GFP from the eft-3 promoter has been inserted into the lin-41 coding sequence (Katic et al., G3 (2015) 5:1649-56).

kpIs100 [pie-1p::Ub(G76V)::GFP::H2B::drp-1 3' UTR + unc-119(+)]. Expresses Ubiquitin::GFP fusion protein in the germ line. The last amino acid of ubiquitin is mutated to valine (G76V), which prevents the cleavage of ubiquitin from GFP by the deubiqutinating enzymes and renders the GFP constitutively targeted for degradation by the proteasome. The strain can be used to assay proteasome activity in the germ line. Reference: Kumar GA & Subramaniam K. Development. 2018 Mar 29;145(7):dev163949. PMID: 29540500
