| Research Abstract |
The flagellates are an assemblage of unicellular organisms with flagella. Our knowledge on the flagellates inhabiting soil habitats in Japan was rather poor. We aimed to investigate biodiversity and phylogenetic affinities of Japanese soil flagellates. We have established over 180 culture strains and studied them with light and electron microscopy. We also investigated phylogenetic relationships by molecular phylogeny. As a result, we identified 24 genera (>50 spp., but exact species number is still to be determined) representing 5 protistan phyla. We also demonstrated that extensive diversification of Paraphysomonas took place in soil, independent of marine or freshwater habitats.
