ozEx76 [cdk-4p::CDK-4::GFP + sur-5::DsRed)]. Maintain by picking DsRed+. ozEx76 is unstable; strain exhibits high levels of lethality and sterilty. ~10% of progeny are fertile. Reference: Fox PM, et al. Development. 2011 Jun;138(11):2223-34.

Heterozygotes are slow growing with WT phenotype. Hets segregate more slow growing WT, embryonic lethals (ozDf1/ozDf1) and DpyUncs which are sick and have a maternal effect lethal (none of the offspring from the DpyUncs survive to reproduce). Maintain by picking WT.

Segregates WT RFP+ heterozygotes, viable non-RFP nemp-1(oz534) homozygotes, and RFP+ Dpy. Maintain by picking wild-type RFP+. About 10-20% of nemp-1(oz534) homozygotes are sterile.

Wild type hermaphrodites and males which produce WT, Dpy, Unc and DpyUnc progeny due to mating or loss of the duplication. Pick WT hermaphrodites and males to maintain.

Heterozygotes are wild-type, and segregate WT heterozygotes, Dpy Mel (unc-62 dpy-11 homozygotes), and dead eggs (eT1 homozygotes). unc-62 dpy-11 homozygotes give only dead embryos (96%) or dead larva (4%).

Maintain at 15C. Temperature-sensitive maternal effect, gastrulation defective. 100% of embryos arrest without gastrulating at 25C.

Withered tail. Adults shorter than WT. Embryonic cell migrations affected: CAN migration with high penetrance. Previously called mig-11.

Vul and Unc.

Heterozygotes are Unc and segregate Uncs, dead eggs, and non-Uncs (dsb-1 homozygotes), which produce 99% inviable embryos due to meiotic nondisjunction. Pick Unc to maintain and check for correct segregation of progeny. we11 is a TCA to TAA nonsense mutation in the dsb-1 coding sequence that introduces a premature stop after leucine 96.

ieSi11 [syp-3p::EmeraldGFP::syp-3::syp-3 3'UTR + Cbr-unc-119(+)] II. ieSi11 was inserted into ttTi5605 II using MosSCI. Expression of GFP::SYP-3 largely complements syp-3(ok758), but some meiotic nondisjunction is detected above the N2 background (85% embryonic viability; ~1% male self-progeny;). GFP::SYP-3 expression is readily detected in spermatocytes and oocytes in the germline, and localizes to the interface between paired homologous chromosomes during most of meiotic prophase.

ieSi21 [sun-1p::sun-1::mRuby::sun-1 3'UTR + Cbr-unc-119(+)] IV. ieSi21 was inserted into cxTi10882 IV using MosSCI. Expression of the transgenic SUN-1::mRuby fusion protein complements the sun-1 deletion allele. SUN-1::mRuby is expressed throughout the germline and in the early embryo, where it localizes to nuclear envelope and associates with chromosome pairing centers during early meiotic prophase. Reference: Rog O, Dernburg AF. Cell Rep. 2015 Mar 10. pii: S2211-1247(15)00178-3.

This strain can be used for auxin-inducible degradation (AID) in germ line and early embryos. References: Zhang L, et al. Development. 2015 Nov 9. pii: dev.129635. Zhang et al., Elife. 2018 Mar 9;7. pii: e30789.

mIs11 [myo-2p::GFP + pes-10p::GFP + F22B7.9::GFP]. Pick WT with dim GFP+ in pharynx to maintain. mIs11 homozygotes will quickly overtake the population if not selected against. GFP expression in 4-cell embryos, pharyngeal muscle and gut. Heterozygotes are WT with dim GFP signal in the pharynx. mIs11 homozygotes are WT with bright GFP in the pharynx. rad-51(lg8701) homozygotes are non-GFP and throw dead eggs.

mIs11 [myo-2p::GFP + pes-10p::GFP + F22B7.9::GFP]. Heterozygotes are wild-type with dim GFP signal in the pharynx. mIs11 homozygotes are wild-type with bright GFP in the pharynx. ieDf2 homozygotes (non-GFP) develop normally but produce 97.5% inviable embryos and a high frequency of males among the surviving self-progeny. Pick WT with dim GFP+ in pharynx to maintain. mIs11 homozygotes will quickly overtake the population if not selected against. GFP expression in 4-cell embryos, pharyngeal muscle and gut. ieDf2 is a deficiency of zim-1, zim-2, zim-3, and him-8 generated by MosDel, resulting in single-copy insertion of a copy of the C. briggsae unc-119 gene on Chromosome IV. The deletion spans the sequences from the beginning of the zim-1 coding sequence through the ttTi22866 Mos1 insertion site.

[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.]
