crEx498 [dpy-14p::ptr-15(+) + sur-5p::GFP]. Pick animals with nuclear GFP throughout body to maintain. Lethal ptr-15 deletion allele marked with pharyngeal GFP [loxP ::myo-2p::GFP::unc-54 3’UTR + rps-27p::neoR::unc-54 3’UTR::loxP]; lethality rescued by hypodermal expression of PTR-15 form crEx498 array. Non-nuclear GFP animals (only pharyngeal expression) will be dead eggs and dead hatchlings. Derived from parental strain VC4151. References: O’Rourke et al. (in revision 2024).

Apparent homozygous lethal or sterile deletion as unbalanced heterozygote. Deletion of 2870 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: AATGAGAGTGCATACGACCCAGAATACAAT. Right flanking sequence: CCTCGGTTCGCATATTCAGAATACCGAAGG. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.
