Strains carrying this gene

Strain Genotype Description
CB1309 lin-2(e1309) X. Vulvaless. M-MATING++ 1-10%WT.
EU149 mex-3(or20)/hT1 I; +/hT1 V; lin-2(e1309) X. 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.
EU1513 aph-1(or28)/hT2 I; +/hT2 [bli-4(e937) let-?(h661)] III; lin-2(e1309) X. or28 is a non-conditional maternal-effect embryonic lethal mutant ; the anterior pharynx is absent. and embryonic lethality is 100% penetrant. Pick single WT heterozygous hermaphrodites to maintain strain; these hets fill up with a mix of dead embryos and larvae [11/16 dead embryos due to aneuploidy from translocation segregation and lethal homozygous hT2; vulvaless due to homozygous lin-2(e1309) mutation; about 10% of lin-2(e1309) worms are leaky and lay eggs/can be mated into]. The homozygous or28 hermaphrodites fill up with dead embryos. The lin-2 background helps to score embryonic lethality for both heterozygotes and or28 homozygotes. or28 is a G to D mis-sense mutation at amino acid position 123.
EU1514 aph-1(or28)/hT2 I; +/hT2 [bli-4(e937) let-?(h661)] III; him-8(ec56) IV; lin-2(e1309) X. or28 is a non-conditional maternal-effect embryonic lethal mutant ; the anterior pharynx is absent. and embryonic lethality is 100% penetrant. Pick single WT heterozygous hermaphrodites to maintain strain; these hets fill up with a mix of dead embryos and larvae [11/16 dead embryos due to aneuploidy from translocation segregation and lethal homozygous hT2; vulvaless due to homozygous lin-2(e1309) mutation; about 10% of lin-2(e1309) worms are leaky and lay eggs/can be mated into]. The homozygous or28 hermaphrodites fill up with dead embryos. The lin-2 background helps to score embryonic lethality for both heterozygotes and or28 homozygotes. Strain produces a lot of males due to him-8(ec56). or28 is a G to D mis-sense mutation at amino acid position 123.
EU407 mom-4(or39)/hT2 I; +/hT2 [bli-4(e937) let-?(h661)] III; him-8(e1489) IV; lin-2(e1309) X.
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.
EU924 zyg-8(or484) III; lin-2(e1309) X. Temperature-sensitive. Maintain at 15C. Reference: Gonczy P, et al. Dev Cell. 2001 Sep;1(3):363-75.
EU931 zyg-8(or490) III; lin-2(e1309) X. Maintain at 15C. Temperature-sensitive embryonic-lethal at restrictive temperature of 26C. Viable embryos at permissive temperature of 15C. Mitotic spindle in one-cell stage embryo assembles normally, but microtubules destabilize at anaphase and spindle becomes mis-positioned toward the posterior pole leading to highly abnormal cleavage and chromosome segregation defects.

MT105 lin-2(n105) X. Temperature sensitive vulvaless. Penetrance: 24% at 15C, 90% at 25C.
MT3881 lin-2(n1610) X. Vul. Suppressor of lin-15(n765).
MT397 lin-2(n397) X. 77% Vul. Probably has a linked suppressor mutation - see WBPaper00002382.
MT491 him-5(e1467) V; lin-2(e1309) X. Vulvaless. Segregates males.
SP1377 dpy-11(e224) V; lin-2(e1309) unc-7(mn384) xol-1(mn467) X. Animals are DpyUncVul. Can mate at low frequency. N2 males X SP1377 fail to give male progeny. Weak unc-7 allele when not in lin-2 background.
