Outline of Final Research Achievements

Primary endosymbiosis, in which bacteria enter (pre-)eukaryotic cells and finally became mitochondria and chloroplasts, plays a critical role in eukaryogenesis. Even today, bacterial invasion into eukaryotic cells takes place every day at sites of infection. In this study, we focused on the relationship between various kinds of intracellular pathogenic/environmental bacteria and their eukaryotic host cells including free-living Acanthamoeba and human cells. We concluded several mechanistic principles which drive the first step of matryoshka-type evolution.
