Outline of Final Research Achievements

Horizontal gene transfer plays an important role in the evolution of bacteria that can add novel abilities, such as environmental tolerance, pathogenicity, and symbiotic nitrogen fixation (SNF) with legume plant. Since SNF is established in a species-specific manner, the horizontal transfer of symbiosis islands may contribute to the host specificity of symbiosis between legume plants and rhizobia, however, knowledge about the host specificity mediated by horizontal transfer of symbiosis islands in nature is very limited.
In this study, genetic relationships between alpine legumes and their rhizobia were analysed and resulted that host specificity of legume-rhizobia symbiosis was conserved partly in genus-specific manner. This result suggested that the horizontal transfer contributes to keep the host specificity to some extent.
