mNeonGreen::AID*::3xFLAG tag inserted at C-terminus of endogenous unk-1 locus. Reference: Gitler L, et al. MicroPubl Biol. 2025 Jun 11;2025:10.17912/micropub.biology.001659. doi: 10.17912/micropub.biology.001659. PMID: 40575442.

Heterozygotes are Unc-93 and segregate more Unc-93, yDf10 homozygotes (dead eggs) and Unc-93 Dpy-17 homozygotes (young dpy-17 larvae are easily recognizable as abnormal spindle-shaped things). Difficult to maintain and use. yDf10 apparently causes semi-sterility (a second strain constructed by the Mark Edgley at the CGC, yDf10/qC1, exhibits same sterility), and unc-93 is Egl and difficult to mate into. Some Df homozygotes are laid, but most remain inside the mother.

H34C03.1. Homozygous sterile deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok1817 homozygotes (sterile adult, no eggs laid). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: TTTTCTCGAAATCCCGTTTG. External right primer: TTTTTCCGGGTCTTACAACG. Internal left primer: ATCGATCCATCGGAACACAT. Internal right primer: TTCAGTGTCTGCCAAAATGC. Internal WT amplicon: 2615 bp. Deletion size: 1056 bp. Deletion left flank: TCTTTCAATTAAAACTTCAAAAATAGATTT. Deletion right flank: ACTGAAAATTGAGGAAATTCAAGAAGGAGA.

Engineered Y145C substitution mutation in endogenously GFP-tagged ahcy-1 locus. ahcy-1(Y145C) mutation mimics the pathogenic human mutation AHCY Y143C. ahcy-1(Y145C) mutants have a prolonged lifespan and are larger than control animals. ahcy-1(Y145C) mutants are fertile and produce a brood of laid and hatched eggs similar to control animals. ahcy-1(Y145C) mutants show a slight increase in SAH and a decrease in SAM levels, leading to an increased SAH to SAM ratio. See WOP122 for control strain. Derived by out-crossing parental strain PHX784 two times to N2. Reference: Thapa P, et al. NPJ Aging. 2023 Dec 5;9(1):27. doi: 10.1038/s41514-023-00125-1.

Reference: Ertekin A, et al. bioRxiv. 2025 May 12:2025.05.09.653132. doi: 10.1101/2025.05.09.653132. PMiD: 40463014.

neSi101 [sun-1p::TIR1::mRuby::eft-3 3'UTR + Cbr-unc-119(+)] IV. GFP reporter inserted into C-terminus of endogenous oma-1 locus. A triple arginine motif upstream of the oma-1 tandem zinc finger domain is mutated to three alanines. AID* degron tag (IAA17) inserted into the endogenous oma-2 locus. When OMA-2 is present, this mutant does not appear to have obvious phenotypes. Auxin-inducible depletion of OMA-2 causes embryonic lethality: animals lay low numbers of nonviable embryos that are often polynucleated and have weak chitin shells.
