| Outline of Final Research Achievements |
All of living organisms have been adapted to global environmental changes on the Earth. It is meaning that they have been rewriting their own genomic information again and again for their survivals, so it would be the first-step to analyze their genomes for the elucidation of adaptation strategies to their living environment. However, it is remaining unsettled of the genomic evaluation for environmental adaptations and evolutionary relationships among related species on the both polar regions and other continents. In order to address the challenge, we have isolated some of bacteria species from the biosphere of a moss pillar in East Antarctica and analyzed the genomes for focusing comparison with ones of related species from other continents. Consequently it was revealed that a lot of genes showed the feature of transferred ones from other species, crossing the species barriers, “horizontal gene transfer (HGT)” in technical terms of evolutionary biology.
