| Outline of Final Research Achievements |
Genetic structure of Calophyllum inophyllum was analyzed to estimate the potential of gene flow in sea-drift seed dispersal plants. Two methods (EST-SSR and MIG-seq analysis) were used, and high levels of genetic differentiation between South Pacific (Solomon islands, Vanuatu, Fiji and Tonga) and Taiwan/Japan was detected. The results suggesting limitation of historical gene flow between two regions. On the Other hand, clear genetic structures along longitude was detected within South Pacific area or Taiwan/Japan. These results indicated the certain level of gene flow within each region has been occured, and potential of gene flow for several hundreds kilometer by sea-drifted seed dispersal was suggested even among island populations.
