Excretory canal defect. Large fluid-filled cysts appear randomly along the excretory canal, especially at the tips: 100% penetrant. Cysts often visible as clear spots by low-power microscopy. Shortened canals. Smaller cysts in amphid sheath. Stop mutation in 2nd Ras-like IRGP domain. Encodes homologue of human IRGC. [NOTE (08/2025): The correct genotype of this strain is exc-1(rh26), not exc-3(rh26) as previously described.]

Mua, not viable. Cytokinesis is defective in both hypodermis and germline resulting in mutinucleate cells.

Excretory canal defect. Canal is invariably short with multiple cysts of varying size clustered along length, especially at the tips. Visible only by Nomarski microscopy. Tail spike is often slightly malformed. Animal is somewhat pale.

Caenorhabditis auriculariae wild isolate. Male-female strain. Maintain by mating at 25C. Can be maintained on NGM with E. coli. C. auriculariae was initially described as an associate of the fruiting bodies of the basidiomycota fungus Auricularia polytricha and recently reisolated from a Platydema mushroom-associated beetle.

Caenorhabditis sp 36 wild isolate. Male-female strain. Maintain by mating. Maintain at 25C. A gonochoristic species isolated from adult weevils (Niphades variegatus), with whom they appear to be tightly associated during its life cycle. A genome comparison highlighted that C. sp. 36 has the smallest genome so far sequenced in the elegans supergroup, despite of being closely related to the largest genome species, C. japonica.

Drug sensitive. No visible phenotype. pgp-1 and pgp-3 deletion alleles.

pgp-3 deletion allele. No visible phenotype. Drug sensitive (colchicine, chloroquine). Throws males: outcrossed with him-8(e1489) so probably contains this mutation.

pgp-1 deletion allele. No visible phenotype. Might be sensitive to drugs.

pkIs584 [gpa-7::GFP + dpy-20(+)]. GFP expression in many neurons, muscle cells, and many neurons in the male tail.
