About Caenorhabditis remanei

Caenorhabditis remanei is a small, free-living roundworm from the "Elegans" supergroup of the Caenorhabditis genus found in North America and Europe in soil, rotten fruits and vegetables and compost. C. remanei is a model for studying natural genetic variation and experimental evolution. They are feed on the bacteria and other micro-organisms associated with plant decay. The biology of C. remanei is similar to that of C. elegans, with a short generation time through four larval stages into an adult. Its closest species is C. latens. C.remanei has has a gonochoristic mating system (obligate outcrossing with male and female adults), unlike the hermaphroditic species such as C. elegans and C. briggsae. All three species are often found at the same site. C. remanei is frequently found associated with snails, slugs, millipedes, mites and pill bugs, which are presumed to transport worms, especially the dormant dauer stage, from one location to another, as with other Caenorhabditids. Genomes of 4 C. remanei strains have been sequenced, and more than 40 laboratory strains are currently available in Caenorhabditis Genetics Center (CGC).
