Heterozygotes are wild-type GFP+ (pharynx), and segregate wild-type GFP+ heterozygotes, Dpy Sterile GFP+, and non-GFP om129 homozygotes (reduced fertility, maternal effect embryonic lethality, and high incidence of male offspring). om129 homozygote defects become more severe over successive generations and are more severe at 25C. om129 is a CRISPR-engineered deletion completely removing cid-1 and pup-2 loci. cid-1 also known as pup-1. nIs189 [myo-2::GFP] integrated in or near qC1. No recombination seen between nIs189 and qC1; fails to complement all markers on qC1. Reference: Yang B, et al. PLoS Genet. 2019 Feb 22;15(2):e1007992. doi: 10.1371/journal.pgen.1007992.

Ray 3 and 4 fusion >60% at non-permissive temp. Ray 1 and 2 fusion about 10% at non-permissive temp. ts period is around L3-L4.

Although hermaphrodites appear WT in other ways, there are some problems with T cell lineages (affecting the phasmids) and tail cell fusions. Variably Dyf. Male tail tip morphogenesis is also defective, resulting in blobby, "leptoderan" tails. Males are infertile due to an inability to properly copulate. tlp-1 encodes a nuclear protein with a single C2H2-type zinc finger domain and an N-terminal "SPLALLA" domain, similar to that of Sp1 transcription factors of vertebrates. The bx85 mutation involves a truncation of TLP-1 due to a frameshift caused by a 5-bp deletion.

WT strain. Isolated by D. Fitch in June 1990 from soil in Scott Emmons' compost heap in the Fort Greene section of Brooklyn, NY. A second strain, DF5038, was isolated from the same location one year later from the head and ventral segments of a male pill bug (Armadillidium vulgare). Hermaphroditic. Males are easily isolated by heat shocking L4 or early adult hermaphrodites at 30C for 6-12 hrs. Grows well at 6-25C on OP50. Dauer larvae accumulate under starved or overcrowded conditions. Freezes easily using C. elegans protocols with 90% viability. Previously called Rhabditis sp. See also WBPaper00003418. Formerly known as Oscheius myriophila.

Male-female strain. Reference WBG 11(4):89. See also WBPaper00001874. May crawl off the plates. Previously called C. vulgaris BK and C. vulgariensis BK. Walter Sudhaus has tentatively described this strain as C. remanei ssp. vulgaris; this description is not official and is contigent upon its being published. See WBPaper00002633 and WBPaper00003993.

Temperature sensitive, semidominant mutant that is Unc when moving backward.
