umnIs52 [myo-2p::mKate2 + NeoR, III: 8856215 (intergenic)] II. Pick viable fertile GFP+ and mKate2+ animals to maintain. Apparent homozygous lethal or sterile deletion balanced with mT1. Heterozygotes are wild-type GFP+ mKate2+, and segregate wild-type GFP+ mKate2+, sterile Dpy non-GFP mKate2+ mT1 homozygotes, and large numbers of arrested aneuploid embryos. Derived from parental strains VH7157 and CGC66. hd7157 is a 1439 bp deletion with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break. Left flanking Sequence: AATTTGATAATCTCTTGAGCAGCTATTCCA; Right flanking sequence: GTTGGTGGCTGACTACTTGCACTACCAGAG. sgRNA #1: CCGACGTACGATGAAATGAC; sgRNA #2: CATCTTCCATAGCTAACGCT. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.

Derived from parental strains VH7180 and CGC66. hd7180 is a 1876 bp deletion with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break.

Heterozygotes are wild-type GFP+ mKate2+, and segregate wild-type GFP+ mKate2+, sterile Dpy non-GFP mKate2+ mT1 homozygotes, and large numbers of arrested aneuploid embryos. Derived from parental strains VH7181 and CGC66. hd7181 is a 1382 bp deletion with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break. Left flanking Sequence: ACTTCCTGCACCCAGAACTCATCAATTCCA; Right flanking sequence: AGCCATGCTAGAATTTCCTTTGGGTCCCCA. sgRNA #1: TCACTACTATTTACTCCACG; sgRNA #2: GGAAGTCTTGCATTAGATGG.

Homozygous viable mutation balanced by GFP- and dpy-10-marked inversion. Heterozygotes are WT with relatively dim pharyngeal GFP signal, and segregate WT dim GFP, Dpy bright GFP (mIn1 homozygotes), and non-GFP ok3294 homozygotes. Pick WT dim GFP and check for correct segregation of progeny to maintain. ok3294 homozygotes are morphologically wild-type but show ~30% reduction in fertilized eggs and a trans-generational increase in sterility. Maintain under normal conditions. Reference: Bickel JS, et al. PLoS Genet. 2010 Jul 22;6(7):e1001028.

Pick wild-type Venus+ animals to maintain. coh-4(tm1857) coh-3(gk112) homozygotes exhibit defects in synaptonemal complex formation on meiotic chromosomes. Many of the progeny from coh-4 coh-3 homozygotes exhibit embryonic lethality, likely due to aneuploidy, but only a few progeny hatch and exhibit the Him phenotype. The coh-3 and coh-4 genes encode nearly identical meiosis-specific kleisins. The deletion mutations can be checked by PCR with the following primers: coh-4(tm1857): TACGCGGCACACATGGGTCT and CAATTCCCCCTAGACATACGATTC; coh-3(gk112): CTCGCAGCGATCGAGCAAGC and AACTGAACATGAGAGCCACGAAG. tmC16 homozygotes are Unc Venus(+). [NOTE: ZT73 with the inversion-based balancer is more amenable to producing coh-4 coh-3 homozygous mutant males than TY5120 with a translocation-based balancer.] Reference: Tabara H, et al.
