对分布于日本山毛榉分布区的45个居群进行了CpDNA变异研究。对两个cpDNA区域进行了测序：trnL（UAA）5 '外显子和trnF（GAA）之间的非编码区，以及trnK区域（包括matK）。13个不同的cpDNA单倍型被确认，每个单倍型被发现是地理结构。系统发育分析表明，在单倍型间存在两个主要分支（I和II+III）。林栖动物是一个外群Clade I的单倍型主要分布沿着日本列岛的日本海一侧，而Clade II + III的单倍型主要分布沿着太平洋一侧。因此，两个主要的cpDNA分支的分布表明，在历史上有两条迁移路线。一个沿着日本海，另一个沿着日本群岛的太平洋一侧。
CpDNA variation in Japanese beech, Fagus crenata (Fagaceae), was studied in 45 populations distributed throughout the species' range. Two cpDNA regions were sequenced: the noncoding region between the trnL (UAA) 5'exon and trnF (GAA), and the trnK region (including matK). Thirteen distinct cpDNA haplotypes were recognized and each haplotype was found to be geographically structured. Two major clades (I and II+III) were revealed in phylogenetic analyses among the haplotypes using F. sylvatica as an outgroup. The haplotypes of Clade I were distributed mainly along the Japan Sea side of the Japanese Archipelago, while those of Clade II + III occurred chiefly along the Pacific Ocean side. Consequently, the distribution of the two major cpDNA clades suggests that there were two migration routes in the history of F. crenata; one along the Japan Sea and the other along the Pacific Ocean side of the Japanese Islands.
