umnIs52 [myo-2p::mKate2 + NeoR, III: 8856215 (intergenic)] II. Homozygous larval arrest. Deletion of 1309 bp with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break in parental strain N2. Heterozygotes are wild-type GFP+ mKate2+, and segregate wild-type GFP+ mKate2+ heterozygotes, GFP+ non-mKate2 arrested larvae (ve698 homozygotes), sterile Dpy non-GFP mKate2+ (mT1 homozygotes), and dead eggs (aneuploids). Maintain by picking wild-type GFP+ mKate2+ and check for correct segregation of progeny. Left flanking Sequence: tctttggagaaggggaaaacaccttctagt ; Right flanking sequence: GACGGCGAGCAGCATgaagaacagtaatac. sgRNA #1: gggaaaacaccttctagttt; sgRNA #2: CTGCTGAGCCGACTCGTAGA. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.

CRISPR/Cas9 engineered tagged endogenous locus.

ZK616.4, ZK616.6. Homozygous lethal deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok2654 homozygotes (mid-larval arrest). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: TGTCTGTCCCATGTCTGCTC. External right primer: TGTTACAATTTGATGGCGGA. Internal left primer: CGGAATTCAAAATCCTGGAA. Internal right primer: TTCAGGGGTTCTCTTGGTTG. Internal WT amplicon: 3222 bp. Deletion size: 1966 bp. Deletion left flank: AAGACCGATTGCTCCGAGGTTTCCAAGGCA. Deletion right flank: TACAAGTATTGATATGGACTACGTCGACAA.
