| Research Abstract |
In this study, in order to retrace origin and evolution of plastids in the green colored dinoflagellate Lepidodinium, its plastid genome was sequenced. Nearly complete sequence of the plastid genome was obtained by the next generation sequencing analysis. Phylogenetic analysis with a large plastid gene dataset and comparative genomics revealed that the Lepidodinium plastids are derived from a green alga closely related to Pedinophyceae and drastic genome rearrangement has been occurred after the plastid acquisition.
