项目摘要

Phylogeographic structures within a plant taxon would imply intraspecific differentiation in genetics, morphologies, reproduction, physiological and/or ecological traits, of which provide good arena for speciation and evolution. In this project, we elucidated phylogeographic structures in plant taxa on high mountains and continental island systems, the Ryukyu Islands, by determining cpDMA haplotypes or Karyomorphology. The distribution of cpDNA haplotypes in three alpine plants (Phyllodoce nipponica, Potentilla matsumurae and Diapensia nipponica) was geographically highly structured, and an abrupt genetic changes were detected between mountains in central Houshu and the Tohoku region. Haplotypes in central Honshu were thought to have diverged, suggesting that mountains in central Honshu served as refugia during the Quaternary climatic oscillations. Moreover, intraspecific variation of chromosome number and cytogeography were examined for samples of Lysimachia mauritiana from the Ryukyu Islands. This plants on the Ryukyu Islands harbor wide range of variation, ranging from 2n=16(6m), 2n=17(6m), 2n=17(7m), 2n=18(4m), 2n=18(5m), 2n=18(6n), 2n=19(5m), 2n=20(2m) to 2n=20(4m). Large islands with high altitude (e.g., Amamioshima Island and Tokunoshima Island) harbor the wider variation, suggesting these islands could act as refugia during the inter- and/or post- glacial transgression in the Quaternary climatic oscillations. On the other hand, islands with lower altitude harbor simple structure in cytotype, which would be attributable to bottleneck effects during the warm periods.
植物分类群内的系统地理结构意味着在遗传、形态、生殖、生理和/或生态性状上的种内分化,这为物种形成和进化提供了良好的舞台。在这个项目中,我们通过测定cpDMA单倍型或核型,阐明了高山和大陆岛系--琉球群岛上的植物分类群的系统地理结构。3种高山植物(日本竹、松毛委陵菜和日本水母)cpDNA单倍型的分布具有高度的地理规律性,在后州中部山区和东北地区之间发现了突变的遗传变异。本州中部的单倍型被认为已经分化,这表明本州中部的山脉在第四纪气候振荡期间是避难所。此外,还对琉球群岛产的金钱草进行了种内染色体数目变异和细胞地理学研究。琉球群岛上的这种植物种类繁多,从2n=16(6m)、2n=17(6m)、2n=17(7m)、2n=18(4m)、2n=18(5m)、2n=18(6n)、2n=19(5m)、2n=20(2m)到2n=20(4m)不等。高海拔的大岛屿(如阿米奥岛和德岛岛)的变化范围更大,表明这些岛屿在第四纪气候振荡的冰间和(或)冰后海侵期间可能起到避难所的作用。另一方面,海拔较低的岛屿细胞类型结构简单,这可能是暖期瓶颈效应的结果。
