Table 1 Mitochondrial gene arrangement identities found in pairwise comparisons between Urechis caupo and various animals. Full taxon names are given here for the annelids Lumbricus terrestris and Platynereis dumerilii, the mollusks Katharina tunicata, Loligo bleekeri, Cepaea nemoralis, and Mytilus edulis, the brachiopods Terebratulina retusa and Terebratalia transversa, the platyhelminths Fasciola hepatica, Taenia crassiceps, Echinococcus multilocularis, and Hymenolepis diminuta, the arthropods Drosophila yakuba, Anopheles gambiae, Artemia franciscana, Daphnia pulex, Apis mellifera, Locusta migratoria, Ixodes hexagonus, Rhiphicephalus sanguineus, Limulus polyphemus and Lithobius forficatus, the nematodes Trichinella spirallis, Onchocerca volvulus, Meloidogyne javanica, Ascaris suum, and Caenorhabditis elegans, the echinoderms Arabacia lixula, Asterina pectinifera, Paracentrotus lividus, Strongylocentrotus purpuratus, and Florometra serratissima, the hemichordate Balanoglossus carnosus, and the chordate Branchiostoma floridae along with the gene order most typical for vertebrates. Complete citations can be found in Boore (1999) or updated by following the "Evolutionary Genomics" link at http://www.jgi.doe.gov/. Contiguous gene arrangements are separated by a comma; a slash indicates a gap containing one or more unrelated genes.
