Strains carrying this gene

Strain Genotype Description
ATD2 par-2(or373) unc-119(ed3) III; zuIs45 V. zuIs45 [nmy-2p::nmy-2::GFP + unc-119(+)] V. Temperature-sensitive maternal-effect lethal. Maintain at 15C. NMY-2::GFP is expressed in the germline and somatic gonad. Cross of JJ1473 and EU822. Unknown if unc-119(ed3) is still present or homozygous in background. NOTE: this strain was originally described as heterozygous for lin-2(e1309), but lin-2 has been lost; this strain is now homozygous wild-type for lin-2. Reference: Small LE & Dawes AT. Mol Biol Cell. 2017 Aug 1;28(16):2220-2231.
ATD7 par-2(ok1723)/sC1[dpy-1(s2170)], unc-119(ed3?) III; zuIs45 V. zuIs45 [nmy-2p::nmy-2::GFP + unc-119(+)] V. Heterozygous worms are wild type and segregate wild type, Par (maternal effect lethal), and Dpy (sC1 homozygotes). Heterozygous and Par adults are indistinguishable on the plate. Maintain by picking wild-type worms and checking for correct segregation of progeny. NMY-2::GFP is expressed in the germline and somatic gonad. Cross of JJ1473 and VC1313. Unknown if unc-119(ed3) is still present or homozygous in background. Reference: Small LE & Dawes AT. Mol Biol Cell. 2017 Aug 1;28(16):2220-2231.
EU1327 par-2(or640) III. Temperature-sensitive embryonic lethal. Maintain at 15C. Reference: O'Rourke SM, et al. PLoS One. 2011 Mar 1;6(3):e16644.
EU822 par-2(or373) III; lin-2(e1309) X. Temperature-sensitive embryonic lethal. Maintain at 15C. Reference: O'Rourke SM, et al. PLoS One. 2011 Mar 1;6(3):e16644.
EU948 par-2(or539) III. Temperature-sensitive embryonic lethal. Maintain at 15C. Reference: O'Rourke SM, et al. PLoS One. 2011 Mar 1;6(3):e16644.
JR1763 wcDf1 dpy-1(e1)/daf-7(e1372) par-2(it46) III. At 25C, heterozygotes are WT and segregate WT, dead eggs and Dauers (which will give only dead eggs if they exit dauer). e1372 and it46 are both temperature sensitive.
KK114 daf-7(e1372) par-2(it5) III. Temperature sensitive-grow at 15C. Par at 25C. Strict maternal effect lethal.
KK1254 par-2(it315[mCherry::par-2]) III. par-2(it315) exhibits a weak maternal effect sterility, suggesting that the tag reduces the protein activity. Note, however, that double homozygous mutants of it315 with pkc-3(it309) or par-6(it310) exhibited partially penetrant and variable maternal effect lethality and maternal effect sterility that was stronger than it315 alone. Thus, although the GFP tags on pkc-3 and par-6 show no effect in an otherwise wild-type background, they do seem to somewhat compromise the activity of the proteins they tag. Made in N2 background.
KK1273 par-2(it328[GFP::par-2]) III. Superficially wild-type. Made in N2 background.
LP637 par-2(cp329[mNG-C1^PAR-2]) III. mNG::PAR-2 endogenously tagged using Cas9-triggered homologous recombination. Reference: Dickinson DJ, et al. Dev Cell. 2017 Aug 21;42(4):416-434.e11. (PMID 28829947).
LV15 unc-45(st601)/daf-7(e1372) par-2(it46) III. st601 is a non-conditional two-fold arrest lethal. Maintain at 25C to see daf-7 par-2 segregants (Daf-7(+) escapers will be Par). WT heterozygotes segregate WT, DafPar, 1/4 lethal eggs and two-fold arrest hatchlings. [3/97: dauers are not giving dead eggs-they are giving more dauers. The par-2 mutation may be lost.]
LV18 unc-45(wc1) dpy-1(e1)/daf-7(e1372) par-2(it46) III. Maintain at 25C. At 25C, heterozygotes are WT and segregate WT, Dauers (dauer escapers will be Par and give only dead eggs), and DpyUcs which arrest as dead eggs (range from twitching multicellulars to 3-folds that hatch). [There is a greater percentage of hatchlings when the mother is heterozygous (wc1 dpy-1/+). There may also be the possibility of near complete maternal rescue (near full-sized, sterile Dpys), but this has not been routinely observed in the balanced strain (as opposed to wc1 dpy-1/+).] Maintain by picking WT at 25C and scoring for correct segregation of progeny. [3/97: The dauers are not giving dead eggs-they are giving other dauers. Appears that the Par mutation is no longer present.]
LV19 unc-45(wc2) dpy-1(e1)/daf-7(e1372) par-2(it46) III. Maintain at 25C. At 25C, heterozygotes are WT and segregate WT, Dauers (escapers will be Par and give only dead eggs) and DpyUncs which are dead eggs (a range of embryonic lethality from multicellular twitchers to 3-folds that do not hatch). Maintain by picking WT at 25C and scoring for correct segregation of progeny. [3/97: the dauers are giving dead eggs.]
UE103 oaSi10 II; par-2(or640) unc-119(ed3) III. oaSi10 [par-5p::GFP::par-5::par-5 3' UTR + unc-119(+)] II. Maintain at 15C. Temperature-sensitive embryonic lethal. MOS single copy insertion of GFP-tagged par-5 under control of its endogenous regulatory sequences. Reference: Mikl, M. and Cowan, CR. Cell Rep. 2014 Sep 11;8(5):1380-90.
VC1313 par-2(ok1723)/sC1 [dpy-1(s2170)] III. F58B6.3. Apparent homozygous lethal deletion chromosome balanced by dpy-1-marked recombination suppressor. Heterozygotes are WT, and segregate WT, Dpy (sC1 homozygotes), and ok1723 homozygotes (arrest stage/phenotype undetermined). Pick WT and check for correct segregation of progeny to maintain.

Heterozygotes are WT, and segregate WT, Dpy (sC1 homozygotes), and ok1890 homozygotes (arrest stage/phenotype undetermined). Pick WT and check for correct segregation of progeny to maintain.
