摘要

The phylogeographical structure of chloroplast DNA haplotypes within Stachyurus praecox Siebold & Zucc (Stachyuraceae) was investigated throughout the species range by comparing the sequences of two intergenrc regions, the trnT(UGU)-trnL(UAA)5'exon and the trnL(UAA)5'exon-trnF(GAA) Eleven cpDNA haplotypes were found within S praecox These haplotypes appeared to be phylogeographically structured. Whereas most haplotypes were concentrated on the Pacific Ocean side of lapan and each haplotype showed a localized distribution, one haplotype ranged widely in the northern part of the archipelago and the Sea of Japan side Four haplotypes in the eastern part of the Pacific Ocean side formed a lineage group. By integrating the geographical distribution and the genealogical relationship of haplotypes, the species range can be divided into at least three major geographical regions; the western part of the Pacific Ocean side, the eastern part of the Pacific Ocean side, and the region from the northern part of the archipelago to the Sea of lapan side. This apparent phylogeographical structure was interpreted to be the result of distribution changes effected by climatic oscillations from the late glacial period to the present.
