Strain Genotype Species Description
KK112 mel-8(b309) unc-4(e120) sqt-1(sc13)/mnC1 [dpy-10(e128) unc-52(e444)] II. C. elegans mel-8 is a maternal effect lethal. WT heterozygotes (sc13 recessive) segregate WT, MelUncSqt (sick and small), mnC1 dpy-10 unc-52 homozygotes (paralyzed Dpys). Rescued by male mating.
KK114 daf-7(e1372) par-2(it5) III. C. elegans Temperature sensitive-grow at 15C. Par at 25C. Strict maternal effect lethal.
KK1216 par-3(it298[par-3::GFP]) III. C. elegans Superficially wild-type. Made in N2 background.
KK1218 par-3(it300[par-3::mCherry]) III. C. elegans Superficially wild-type. Made in N2 background.
KK1228 pkc-3(it309[GFP::pkc-3]) II. C. elegans Superficially wild-type. Note that double homozygous mutants of pkc-3(it309) with par-2(it315) exhibited partially penetrant and variable maternal effect lethality and maternal effect sterility that was stronger than it315 alone. Thus, although the GFP tag on pkc-3 shows no effect in an otherwise wild-type background, it does seem to somewhat compromise the activity of the protein it tags. Made in N2 background.
KK1248 par-6(it319[par-6::GFP]) I. C. elegans Superficially wild-type. Made in N2 background.
KK1254 par-2(it315[mCherry::par-2]) III. C. elegans 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.
KK1262 par-1(it324[par-1::GFP::par-1 exon11a]) V. C. elegans Superficially wild-type. Made in N2 background.
KK1273 par-2(it328[GFP::par-2]) III. C. elegans Superficially wild-type. Made in N2 background.

KK288 sqt-3(sc8) par-1(b274) IV/nT1 [unc-?(n754) let-?] (IV;V). C. elegans Heterozygotes are Unc and segregate Unc, RolPar (adult homozygotes lay eggs that don't hatch) and dead eggs. nT1[unc-?(n754) let-?] is dominant Unc and recessive lethal.

Strict maternal effect lethal.
KK300 par-4(it57) V. C. elegans Temperature-sensitive maternal effect lethal (strict). Maintain at 15-16C (95% of embyros hatch). Shift to 25C for Par phenotype (no hatching embryos).
