| Research Abstract |
Parmales has been proposed as a close relative of diatoms, which are the most successful phytoplankton group in modern oceans. Because the origin of diatoms has not yet been clearly established, Parmales may play a key role in answering this question. However, we still have very little biological information on this alga, due to lack of laboratory investigations. Recently, we isolated the first ever culture of Parmales. To explore the evolutionary link between Parmales and diatoms, we investigated the growth characteristics, phylogeny, formation of silica cell wall and life cycle of Parmales by culture experiments and field experiments.
