vlc19[ast-1::GFP] II. Superficially wild-type. Endogenous ast-1 locus tagged with GFP using Cas9-triggered homologous recombination. GFP was inserted at the C-terminus using a 9 amino acid flexible linker present in the plasmids (Dickinson et al., 2015). Reference: Lloret-Fernández et al. eLife 2018;7:e32785 DOI: 10.7554/eLife.32785.

rhIs4 [glr-1p::GFP + dpy-20(+)] III. hdEx237 [ast-1(+) + rol-6(su1006)]. hd92 arrests as L1 due to pharyngeal differentiation defects; ventral cord midline crossing defects; rescued with ast-1(+) transgene. Rollers.

T08H4.3. Homozygous lethal deletion chromosome balanced by GFP- and dpy-10-marked inversion. Heterozygotes are WT with relatively dim pharyngeal GFP signal, and segregate WT dim GFP, Dpy bright GFP (mIn1 homozygotes), and non-GFP ok2359 homozygotes (embryonic or early larval arrest). Pick WT dim GFP and check for correct segregation of progeny to maintain. External left primer: ATAGGCCACCAGCTTCTCAA. External right primer: CCCAACTACCAACACAGGCT. Internal left primer: GACAATAGCGAAGAGCCGTC. Internal right primer: TGTGATCAAGTATTCGGCCA. Internal WT amplicon: 2386 bp. Deletion size: 946 bp. Deletion left flank: CACAGATAATAGAGCTTTTTGGAGCAGCAC. Deletion right flank: TTCATCGTCGTCGCCGAATCATCGGCGGAA.
