基于细胞器DNA序列地理分析和生态位模型（ENM），研究了日本枫杨（Pterocarya rhoifolia）在第四纪气候振荡中的变化历史，特别是末次盛冰期（LGM）的变化。通过对53个居群的376个个体的叶绿体DNA序列分析，确定了该种的系统地理格局。分子方差的空间分析表明，目前的冰川地理结构将雕塑从每个冰川避难所，这将在第四纪气候振荡期间重复多次的多个范围的变化。高单倍型多样性和私人单倍型检测在日本西南部，其中翼果是目前罕见的，主要是在高山，而在日本最北部，单倍型多样性低，虽然这种植物是相当普遍的，目前。根据ENM方法，在末次盛冰期，气候适宜的分布区没有恢复在日本东北部，但在日本西南部的低地。我们的综合结果表明，日本翼果主要存在于日本西南部的低地和36.5°N以下的海岸线在LGM期间，导致了冰后期的范围从避难所在日本西南部和低纬度东北部的各个地区的扩张，并从南部避难所/避难所在日本最北部的大范围的北化。西南部和沿海避难所发挥了作用，在塑造目前的单倍型多样性和独特的地理结构，而一些后方边缘人口，窝藏独特的单倍型，也一直保持。
Based on organelle DNA phylogeographic analyses and ecological niche modeling (ENM), we investigated the range-shift history of the Japanese wingnut (Pterocarya rhoifolia) during the Quaternary climatic oscillations with particular emphasis on the Last Glacial Maximum (LGM). Phylogeographic patterns of this species were determined using 376 individuals from 53 populations for chloroplast DNA sequencing of three spacers. Spatial analysis of molecular variance revealed that the current phylogeographic structure would be sculptured by multiple range shifts from each glacial refugium, which would have been repeated several times during the Quaternary climatic oscillations. High haplotype diversity and private haplotypes were detected in southwestern Japan, where wingnut is currently infrequent and found mainly in high mountains, whereas in northernmost Japan, haplotype diversity was low though this plant is quite common at present. According to ENM approach, during the LGM, the climatically suitable distribution areas were not recovered in northeastern Japan but in lowlands of southwestern Japan. Our combined results suggest that Japanese wingnut primarily persisted in the lowlands of southwestern Japan and coastlines below 36.5°N latitude during the LGM, having led to the postglacial range expansion from the refugia in each area of southwestern and lower latitudinal northeastern Japan, and to the wide-range recolonization from the southerly refugium/refugia to the north in northernmost Japan. The southwestern and coastal refugia have played a role in shaping the current haplotype diversity and phylogeographic structure, whereas some rear edge populations, harboring unique haplotypes, have been also maintained.
