| Outline of Final Research Achievements |
Parmales are an unknown small marine phytoplankton group with a silicified cell wa ll. Based on similarities in cell wall structure, Parmales has been proposed as a close relative of diatom s, the most successful microalgal group in modern oceans, and may play a key role in understanding their o rigin of silica cell wall and early evolution, which have not yet been clearly established. Recently, we i solated the first ever culture of Parmales in the Oyashio region of Japan. Molecular phylogenetic analysis of this culture indicated that Parmales was within the bolidophycean clade of autotrophic naked flagellates and a sister group of diatoms. We have studied on Parmales using ecological, physiological, genomic and biogeochemical approaches and analyzed their silica cell wall formation and mitosis process, global oceanic distribution , life cycle, genome , life cycle and specific biomarkers (molecular fossils).
