Outline of Final Research Achievements

Population genetic analyses based on microsatellite markers were conducted on Gentiana scabra and Salvia japonica in eastern Japan to examine the origin of their riparian populations. For Gentiana scabra, the result of STRUCTURE simulations, riparian populations were clustered separately, except for those of some Shikoku populations. Furthermore, all riparian populations did not consist a cluster with inland populations. These results suggested that the most of riparian populations might be independently originated form local ancestral populations in Gentiana scabra. Clustering analyses on raiperian Salvia japonica populations also supported their independent origin from their local ancestral populations.
