Caenorhabditis briggsae is a small nematode, closely related to Caenorhabditis elegans. The differences between the two species are subtle. The male tail in C. briggsae has a slightly different morphology from C. elegans. Other differences include changes in vulval precursor competence and the placement of the excretory duct opening. [1]
Caenorhabditis briggsae - genome sequence finished 2003 at Washington University in St. Louis. [11] C. briggsae is the second-best studied species in the genus. While C. briggsae are also mostly XX protandrous hermaphrodites, they are not the closest relatives to C. elegans , and the hermaphroditic reproductive strategy of these species, as ...
C. nigoni is noteworthy because it is very closely related to the hermaphroditic species, C. briggsae.Despite substantial differences between C. nigoni and C. briggsae in their modes of sexual reproduction (50:50% female:male versus 99:1% hermaphrodite:male, respectively), their genome sizes (129 Mb versus 108 Mb, respectively), [4] and their protein-coding gene counts (29,167 versus 22,313 ...
WormBase is an online biological database about the biology and genome of the nematode model organism Caenorhabditis elegans and contains information about other related nematodes. [1] [2] WormBase is used by the C. elegans research community both as an information resource and as a place to publish and distribute their results. The database is ...
Caenorhabditis sinica, is a species of Caenorhabditis nematodes, belonging to the Elegans super-group and Elegans group within the genus. [2] It is closely related to several species isolated from the lands adjacent to the Indian and Pacific Oceans, as well as to C. briggsae and C. nigoni. The species was known as “C. sp. 5” prior to 2014. [1]
Caenorhabditis tropicalis is a species of Caenorhabditis nematodes, belonging to the Elegans super-group and Elegans group within the genus. [2] It is a close relative of C. wallacei. C. tropicalis is collected frequently in tropical South America, Caribbean islands, and various islands in the Indian and Pacific Oceans from rotting fruit ...
Dougherty and Victor Nigon obtained the first mutant, from a laboratory culture of the closely related nematode Caenorhabditis briggsae. [5] However much of the early laboratory work on Caenorhabditis nematodes was directed towards the establishment of a defined axenic culture medium. [6]
The analysis of sequences of three nuclear genes shows that the Diploscapter, Protorhabditis and Prodontorhabditis genera group together to form the 'Protorhabditis' group, the sister group of the Caenorhabditis species, all included in the 'Eurhabditis' group of Rhabditidae genera.
