| Outline of Final Research Achievements |
It has been thought that the symbiotic associations between ciliates and their endosymbiotic algae are temporary. We executed continuous sampling of the ciliates and their algal DNA analyses. In consequence, we found that comparatively large number of ciliate species maintain their own algae, and the small number of algal species are shared among different host species. It was found some differences, e.g., nucleotide substitutions in spacer region, in the same species of algae among different host species, which may also indicate the persistent symbioses.
