wIs51 [SCMp::GFP + unc-119(+)] V. GFP expression in seam cells. Gain-of-function allele causing retarded heterochronic defects including extra seam cells and absence of alae in young adult animals. ms354 is a 1120 bp deletion removing most of the hbl-1 3'UTR including all let-7-complementary sites. Sequences flanking the deletion: TTCTAATCATGGCCAGTTTCTTGCA and GTGCGTTCTTCTGTCATCATGTACA. Reference: Ilbay O & Ambros A. Development. 2019 Oct 9. pii: dev.183111. doi: 10.1242/dev.183111.

Heterozygotes have myo-2::GFP [qIs48] strongly expressed in the pharynx and are viable at 25C. 100% of sep-1 homozygotes are strongly Sterile Unc at 25C (at 20C, 100% are Sterile but no so Unc). Up to 30% of the homozygotes are Sterile at 16C. hT2[qIs48] homozygotes are dead. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype.

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.

High physiological germ-line apoptosis. op234 was originally assigned to gla-1, but cloning revealed it to be a point mutation in cpb-3 causing a C520Y substitution at an invariant cysteine within the conserved C/H domain.

Heterozygotes are WT GFP+ and segregate non-glowing hus-1 homozygotes and very rare homozygous hT2 glowing animals, and dead eggs. qIs48 is an insertion of ccEx9747 with markers: myo-2::GFP expressed brightly in the pharynx throughout development, pes-10::GFP expressed in embryos, and gut promoter driving GFP in the intestine. hus-1(op244) mutants from homozygous parents show an incompletely penetrant maternal effect embryonic lethality. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype.

Pan-neuronal expression of a truncated variant of Arabidopsis thaliana Cryptochrome-2 fused to synaptogyrin. If illuminated with blue light, synaptic vesicles cluster, resulting in inhibition of synaptic transmission. Synaptic transmission is restored within 15 minutes in the absence of light (ca. 6.5min time constant), resulting in normal wild type behavior afterwards. Reference: Vettkotter D, et al.
