ZK20.3, ZK20.4. Homozygous lethal/sterile deletion chromosome 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 ok1910 homozygotes (late larval arrest or sterile adult with no eggs). Pick WT dim GFP and check for correct segregation of progeny to maintain. External left primer: CAGACTTGCATCGTCTCCAA. External right primer: AGAGCCTTCTCAACTGCGAC. Internal left primer: TGACAGGATTCTGGCCTTTT. Internal right primer: AGAAGATTTTTATGGGCGGC. Internal WT amplicon: 2172 bp. Deletion size: 1030 bp. Deletion left flank: AAATTTCTCACTTCGTAGCATCCAAATCTG. Deletion right flank: AATCTGGTTCTTGGTCAGCAGCATCATCAG. Attribution: This strain was provided by the C. elegans Reverse Genetics Core Facility at the University of British Columbia, which is part of the international C. elegans Gene Knockout Consortium, which should be acknowledged in any publications resulting from its use.

umnIs37 [myo-2p::mKate2 + NeoR, II: 11755713 (intergenic)] II. Pick viable fertile GFP+ and mKate2+ animals to maintain. Apparent homozygous lethal or sterile deletion balanced with mnC1. Heterozygotes are wild-type GFP+ mKate2+, and segregate wild-type GFP+ mKate2+, GFP+ homozygotes and paralysed DpyUnc mKate2+ mnC1 homozygotes. Derived from parental strains VH7182 and CGC48. hd7182 is a 1757 bp deletion with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break. Left flanking Sequence: TTGCACAACTCTGTGGAATATCCATTTCAC; Right flanking sequence: ATAGCTTCTTCGCTTATTTTTCCAGACATC. sgRNA #1: ACGCTCGAATCGCAAACTGG; sgRNA #2: GCAGGAACAGGCCGAAAGGG. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.
