“…The Japanese Archipelago extends along a 3,000 km line from the northeast to the southwest, covering a wide range of climatic zones, from subarctic to subtropical. The distribution ranges of most plants in the Japanese Archipelago have repeatedly shifted following climatic changes during the Quaternary (Ikeda, Carlsen, Fujii, Brochmann, & Setoguchi, ; Kubota, Kusumoto, Shiono, & Tanaka, ; Yoshida, Kudo, Shimada, Hashizume, & Ono, ). Because their range shifts in the archipelago interacted with the neighboring continent of Asia as well as associated islands (Chiang et al, ; Fujii, Ueda, Watano, & Shimizu, ; Ikeda, Higashi, Yakubov, Barkalov, & Setoguchi, ; Lee, Lee, & Choi, ; Nakamura et al, ; Sakaguchi et al, ), elucidating the historical interaction with the continent and surrounding islands is necessary to understand the origin of Japanese flora.…”

The genetic diversity and structure of Pulsatilla cernua, a continental‐grassland relict, were investigated using variations in chloroplast DNA (cpDNA) and microsatellites of nuclear DNA. In the analyses of three cpDNA regions, 17 haplotypes were found in 24 populations of P. cernua from Japan, Korea, and Russia. Although the route and time of migration between the continent of Asia and Japan could not be well resolved, the cpDNA haplotype network suggests the existence of several ancient lineages in Japan and a recent secondary migration from Japan to the continent. Microsatellite analyses did not indicate genetic structure among the Japanese populations, indicating the existence of gene flow across the distribution area until recently. These results indicate that the present fragmentation of P. cernua in Japan may reflect a rapid, recent reduction from a previously large, continuous distribution.
