| Outline of Final Research Achievements |
Evolution of urochordates based on the diversification of mitochondrial (mt) genome structures and molecular phylogenetic study using mt genes was discussed.
Fritillaria haplostoma (Appendicularia, Fritillaridae) was suggested to have at least two circular mt genomes (ca. 4 kbps and ca. 6 kbps). From the molecular phylogenetic analyses using 12 mt protein genes, Thaliacea was suggested to be an ingroup of Phlebobranchia of Enterogona, In addition, Rhopalaea sp., which is the member of Diazonidae (or Diazoninae) of Phlebobranchia in classical taxonomy, was suggested to be a member of Applousobranchia of Enterogona. Thus, reconsideration of taxonomy in Thaliacea, Phlebobranchia, and Applousobranchia is desired.
