Caenorhabditis briggsae This worm is closely related to C. elegans and they are morphologically almost indistinguishable Lineage: Eukaryota[15557]; Metazoa[7782]; Ecdysozoa[3517]; Nematoda[201]; Chromadorea[181]; Rhabditida[177]; Rhabditina[77]; Rhabditomorpha[63]; Rhabditoidea[39]; Rhabditidae[39]; Peloderinae[26]; Caenorhabditis[25]; Caenorhabditis briggsae[1]

Although Caenorhabditis briggsae and Caenorhabditis elegans are nearly morphologically identical, their evolutionary history is approximately 50 million years apart. The comparative genome analysis between these two species can reveal important functional regions of the genome, and provide a useful tool in the identification of regulatory More...regions and rarely expressed coding regions.
Caenorhabditis briggsae has a diploid genome of approximately 104 Mb, organized in six chromosomes. The C. briggsae genomic sequence has been submitted to the GenBank WGS division as the 578 entries accessioned CAAC01000001 through CAAC01000578. Less...
