Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc spo-11(me44) homozygotes, and dead eggs (nT1 homozygotes). spo-11(me44) homozygotes are viable and produce more than 90% dead eggs (a large fraction of the survivors are males — strong Him phenotype); cytologically they lack chiasmata in diakinesis-stage oocytes and lack RAD-51 foci. Maintain by picking Unc.

meIs1 [pie-1p::GFP::lacI + unc-119(+)]. meIs4 [lac-O + rol-6(su1006) + lacO] IV. Pick Rol worms to maintain. This strain throws both Rol and non-Rol worms, seemingly due to random silencing of rol-6(su1006) in the lacO array, meIs4. The strain expresses GFP::LacI in the gonad and embryos that is observed as foci (of lacO target) and nuclear haze. The expression level of GFP::LacI occasionally becomes low possibly due to random silencing of meIs1. If this happens, heat shock the strain at 25°C for 3 days, and pick a clone that exhibits bright GFP signals. Even at the highest expression level, GFP signal is too weak to detect with a fluorescent dissection microscope, and it is necessary to use a regular compound fluorescent microscope with an oil immersion 60X or 100X objective. The NA of the objective should be higher than 1.4. Reference: Bilgir C, et al. G3 (Bethesda). 2013 Mar 11. pii: g3.112.005165v1.

Heterozygotes are WT and GFP+. Segregate syp-3(me42) homozygotes that are non-GFP and lay mostly dead eggs; these mutants form abnormal synaptonemal complex formation during meiosis. Homozygous hT2[bli-4 let-? qIs48] animals are inviable.

Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc him-3(me80) homozygotes, and dead eggs (nT1 homozygotes). him-3(me80) homozygotes are viable and non-Unc. They produce more than 85% dead eggs and a large fraction (11%) of the survivors are males (Him phenotype). Cytologically they exhibit a reduced level of HIM-3 loading and fewer stretches of SYP-1 than WT. In diakinesis-stage oocytes, they contain a mixture of bivalents and univalents. Maintain by picking Unc.

meIs5 [him-17::GFP + unc-119(+)]. him-17::GFP is expressed in the germline. meIs5 not mapped.

Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc syp-1(me17) homozygotes, and dead eggs (nT1 homozygotes). syp-1(me17) homozygotes produce 95% dead embryos and 38% males. Cytologically they lack chiasmata in diakinesis-stage oocytes, exhibit persistent polarized nuclear organization during earlier meiotic prophase, lack synaptonemal complexes, and exhibit unstable pairing of homologous chromosomes. qIs50 is an insertion of ccEx9747 with markers: myo-2::GFP expressed brightly in the pharynx throughout development, pes-10::GFP expressed in embryos, and a gut promoter (F22B7.9) driving GFP in the intestine.

qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP ok197 homozygotes (viable, sterile), wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. rad-50 homozygotes are viable, produce more than 95% dead eggs and a large fraction of the survivors are male (Him phenotype). Pick wild-type GFP+ and check for correct segregation of progeny to maintain. Reference: Hayashi M, et al. PLoS Genet. 2007 Nov;3(11):e191.
