Apparent homozygous lethal or sterile deletion as unbalanced heterozygote. Deletion of 24013 bp with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break. Pick viable fertile GFP+ animals to maintain. Left flanking sequence: TTTTCACGCTCTTTCCCCCATTTTTCCCCA. Right flanking sequence: GGGTAGGCAACATTTTTATTTCCAACTTTT. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation. [NOTE: Maintain this strain with care! Non-GFP animals can quickly overtake a population. GFP expression is mottled: the pharynx can look sort of sectored, with bright portions and dim or non-GFP portions, and some GFP animals will throw only non-GFP progeny.]
