||mei-1(or1178) I; ItIs37 IV; ojIs1.
||ltIs37 [pie-1p::mCherry::his-58 + unc-119(+)] IV. ojIs1 [pie-1p::GFP::tbb-2 + unc-119(+)]. Maintain at 15C; sterile at 26C. Shift to restrictive temperature (26C) for 3-6 hours to induce oocyte meiotic spindle phenotype and bypass sterility. [NOTE: the ltIs37 [pie-1p::mCherry::his-58 + unc-119(+)] IV transgene was previously annotated as itIs37 in this strain. The correct name of the transgene is ltIs37 and not itIs37.] Reference: Connolly A, et. al. Mol Biol Cell. 2014 Apr;25(8):1298-311.
||mei-1(b284) unc-29(e1072)/mei-1(ct46) unc-13(e1091) I.
||Heterozygotes are WT. ct46 is a dominant, temperature sensitive maternal effect lethal. ct46 homozygotes are viable and fertile at 15C. b284 is a non-conditional, recessive maternal effect lethal. Heterozygotes give more viable progeny at 15C than 25C.
||mei-1(ct46) unc-13(e1091) I; unc-119(ed3) III; abcIs3.
||abcIs3 [pie-1p::ebp-2::GFP + unc-119(+)]. Embryonic-lethal at 25ºC due to dominant gain-of-function mutation mei-1(ct46), and Uncoordinated due to unc-13 mutation. Maternal expression of EBP-2::GFP microtubule end-binding protein. EBP-2 encodes an EB1-like protein (end-binding) that, in early embryos, locates to the growing tips of microtubules. A strong fluorescent signal localizes to the centrosomes of early embryos due to a high concentration of polymerizing microtubules. mei-1(ct46)-based ectopic microtubule severing causes mitotic spindle defects in the early embryo.

||mei-1(ok2000) I/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III).
||T01G9.5. Homozygous sterile deletion chromosome balanced by bli-4- and GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP ok2000 homozygotes (sterile, lays eggs that don't hatch). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: TAATTGTTTGTCGCGGATGA.
