| Outline of Final Research Achievements |
Various eukaryotic organisms that lack canonical mitochondria with oxygen respiration but instead possess mitochondrion related organelles (MROs) are present in anaerobic/microaerophilic environments. MROs are considered to be reduced mitochondria resulted from an adaptation to such environments. However, very little is known about diversity and evolution of these organisms and their MROs. In this study in order to further understand the diversity of MRO-containing organisms, we isolate various novel eukaryotic microorganisms from anaerobic/microaerophilic environments in Palau, Malaysia, and Japan and characterized these organisms by morphological, molecular phylogenetic, and comparative transcriptome analyses.
