DG4269 C. elegans mex-3(tn1753[gfp::3xflag::mex-3]) I. Show Description
Superficially wild type
EU149 C. elegans mex-3(or20)/hT1 I; +/hT1 V; lin-2(e1309) X. Show Description
Strain is egg-laying defective. Homozygous mex-3(or20) is a non-conditional maternal effect lethal: worms fill up with dead eggs. Heterozygotes bag with 11/16 dead embryos and larvae. About 10% of worms can lay eggs and be mated into for outcrossing. The mex-3(or20) mutant embryos produce excess body wall muscle anteriorly.
JJ478 C. elegans mex-3(zu155) egl-30(n686)/hT1 I; +/hT1 V. Show Description
Heterozygotes are WT and segregate WT, Egls which give only dead eggs, dead eggs, and mid-larval lethals (hT1 homozygotes)
JJ1014 C. elegans mex-3(zu155) dpy-5(e61)/hT1 I; pos-1(zu148) unc-42(e270)/hT1 V. Show Description
The double heterozygote is WT. WT will segregate WT, DpyUncs, mid-larval lethal (hT1 homozygotes) and dead eggs. The DpyUncs are homozygous for zu155 and zu148 and will segregate only dead embryos; the dead embryos have excess hypodermis and muscle and lack germ cells and intestine.
HCC21 C. elegans hwSi3 II; unc-119(ed9) III. Show Description
hwSi3 [pie-1p::GFP::mex-3::pie-1 3'UTR + unc-119(+)] II. Worms are healthiest at 15C. Shift to 25C overnight to increase brightness of GFP. Mos1-mediated single-copy insertion (MosSCI) into EG4322. GFP-tagged transgene expressing full-length MEX-3 uniformly throughout oocytes and early embryos through the 4-cell stage. GFP::MEX-3 then mirrors endogenous MEX-3, disappearing from somatic cells by about the 12-cell stage. Also detected in P granules. GFP::MEX-3 can replace endogenous MEX-3. Reference: Huang NN & Hunter CP. Gene. 2015 Jan 10;554(2):160-73.
HCC27 C. elegans hwSi8 II; unc-119(ed9) III. Show Description
hwSi8 [pie-1p::GFP::mex-3(601-1248)::pie-1 3'UTR + unc-119(+)] II. Worms are healthiest at 15C. Shift to 25C overnight to increase brightness of GFP. Mos1-mediated single-copy insertion (MosSCI) into EG4322. GFP-tagged transgene expressing a portion of MEX-3(601-1248) required for protein degradation. At about the 12-cell stage, soma-germline asymmetry is briefly visible before GFP::MEX-3(601-1248) becomes undetectable even in the germline blastomeres. Detected weakly on P granules only in the presence of endogenous MEX. Reference: Huang NN & Hunter CP. Gene. 2015 Jan 10;554(2):160-73.
HCC31 C. elegans hwSi13 II; unc-119(ed9) III. Show Description
hwSi13 [pie-1p::GFP::mex-3(2-636)::pie-1 3'UTR + unc-119(+)] II. Worms are healthiest at 15C. Shift to 25C overnight to increase brightness of GFP. Mos1-mediated single-copy insertion (MosSCI) into EG4322. GFP-tagged transgene expressing truncated MEX-3 that is missing a portion required for protein degradation. GFP::MEX-3(2-636) is extraordinarily stable, persisting in somatic cells through the comma stage (~550 cells) at levels similar to those in 1- and 2-cell embryos. Also detected on P granules through hatching. Reference: Huang NN & Hunter CP. Gene. 2015 Jan 10;554(2):160-73.
JH2333 C. elegans unc-119(ed3) III; axIs1688. Show Description
axIs1688 [pie-1p::GFP::histone H2B::mex-3 3'utr + unc-119(+)]. Transgene is prone to silencing -- maintain at 25C.
WRM2 C. elegans sprSi2 II; unc-119(ed3) III. Show Description
sprSi2 [pie-1p::GFP::histone-H2B::nos-2 3'UTR + Cbr-unc-119(+)] II. Fluorescence in all cells of early embryo. This fluorescence reporter has mutations in both MEX-3 binding sites and shows ectopic expression relative to strain WRM1. Reference: Pagano JM, et al.
