Lotus japonicus is a model plant which glows wild in Japan. It is considered the naturalized plant since prehistoric times. Whole genomic DNA of Lotus japonicus was analysed, and various genetic information are released widely. We use the exhibited microsatellite marker, and analysed wild populations of Lotus japonicus in Japan. Cluster analysis showed that Lotus japonicus of Japan was clearly divided into two geographically different groups.The first group, Honshu type consisted of wildness groups of Hokkaido, Honshu, Shikoku, and Kyushu.As for another group, Nansei type containd the populations of Nansei islands.It became clear that both types differ genetically. Since the population obtained from Tsushima Island was also the Honshu type, it was possible that Lotus japonicus of Japan has the group which went Nansei islands north from the south, and the group which carried out distribution expansion in various parts of Honshu through Tsushima from the Korean Peninsula.

荷花是日本野生的一种模式植物。它被认为是自史前时代以来的归化植物。对百脉根全基因组DNA进行了分析，揭示了百脉根的各种遗传信息。我们使用所展示的微卫星标记，并分析了日本百脉根野生种群。聚类分析表明，日本莲属植物可明显分为两个地理上不同的类群，第一个类群是由北海道、本州、四国和九州的野生类群组成的本州类型，第二个类群是由南西诸岛的野生类群组成的南西类型，这两个类群在遗传上存在明显差异。由于从对马岛获得的群体也是本州类型，因此日本莲舫可能有从南向南向北进入南西诸岛的群体，以及从朝鲜半岛经对马岛向本州各地进行分布扩张的群体。
