| Research Abstract |
By determination of complete nucleotide sequences of urochordate mitochondrial genomes, we analyzed urochordate phylogeny based on the primary sequences and higher information. We analyzed urochordate phylogeny based on mitochondrial protein gene sequences including a pyrosomatid Pyrosoma atlanticum. The analysis suggested that the Thaliacea is a subgroup of Enterogona. Entrogona(Stolidobranchia and Aplousobranchia) seems to be paraphyletic group. In particular, Cioninae of Cionidae, Stolidobranchia is suggested to be sister group of Aplousobranchia, and Diazoninae of Cioninae is suggested to be the in-group of Aplousobranchia.
