Homozygous early larval arrest as an unbalanced heterozygote. Deletion of 852 bp with Calarco/Colaiacovo selection cassette conferring myo-2 GFP and G418 resistance inserted at break in parental strain N2. Heterozygotes are wild-type dim GFP+, and segregate wild-type dim GFP+, bright GFP+ arrested larvae (ve735 homozygotes) and non-GFP wild-type homozygotes. Maintain by picking wild-type dim GFP+. Left flanking Sequence: tttattagcattttttctagaatgtacacg ; Right flanking sequence: tttttttctgtaaattttttacgaaaatat. sgRNA #3: CGTCACCGATAAGCTATCGT; sgRNA #4: ggtaaactacacgcgtggcc. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation. Note: This allele cannot be balanced by sC4 because it is contained within a deleted region.
