Apparent homozygous lethal or sterile deletion as unbalanced heterozygote. Deletion of 2222 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: AGATGAGACGATGTCAGAGAAGAAATTGGA. Right flanking sequence: ATAGAGTTCCCATTATTGTGAAGGATTAAG. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.

Larval lethal mutation balanced by tmC24 [F23D12.4(tmIs1240) unc-9(tm9719)]. Balancer marked with myo-2p::Venus. Maintain by picking non-Unc GFP+ animals. Heterozygotes are wild-type GFP+ and segregate wild-type GFP+ heterozygotes, non-GFP mg663 homozygotes (lethal), and Unc GFP+ (homozygous tmC24). Reference: Warnhoff K & Ruvkun G.
