||+/mT1 [umnIs52] II; psd-1(gk5580[loxP + myo-2p::GFP::unc-54 3' UTR + rps-27p::neoR::unc-54 3' UTR + loxP])/mT1 [dpy-10(e128)] III.
||umnIs52 [myo-2p::mKate2 + NeoR, III: 8856215 (intergenic)] II. Pick viable fertile GFP+ and mKate2+ animals to maintain. Apparent homozygous lethal or sterile deletion as unbalanced heterozygote. Heterozygotes are wild-type GFP+ mKate2+, and segregate wild-type GFP+ mKate2+, GFP+ non-mKate2 (gk5580 homozygotes), sterile Dpy non-GFP mKate2+ mT1 homozygotes, and large numbers of arrested aneuploid embryos. Derived from parental strains VC4509 and CGC66. gk5580 is a 6731 bp deletion with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break. Left flanking sequence: TACAAGCTCGACACTTGCCACGTGGACTAA. Right flanking sequence: TCTGGCGGACCGAAGAACGTTGAAAAGTGG. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.
