摘要

山区构造运动和季风等环境因素会阻碍特异性基因的内部和之间流动,从而加强基因分化。然而,由于使用的分子标记不同,在物种内部检测到的系统地理断裂也可能不同,生物特征可能是一个主要的干扰因素。红豆杉是一种分布于四川盆地的脆弱孑遗物种。在此,我们利用四川盆地周围18个种群的叶绿体DNA和限制性位点相关DNA测序数据,研究了红豆杉的系统地理格局和进化历史。24个叶绿体单倍型在大约16.7万年前分为西部和东部两个系,这与中新世早中期东亚季风系统的加强基本吻合。cpDNA 和核 DNA 数据集都一致确定了独特的西部和东部世系,其系统地理断裂与中国-喜马拉雅和中国-日本森林亚王国的边界一致。然而,与核基因数据不同的是,cpDNA 数据显示东部世系在长江沿岸进一步分化为北部和南部群,这一结果很可能反映了花粉与种子传播范围的差异。在更新世的倒数第二个(Riss)冰川期气温下降期间,胡蜂经历了一次遗传瓶颈事件,生态位建模表明,随后的种群扩张发生在最后一个间冰期。我们的发现不仅为该物种的保护奠定了基础,而且也是地理和气候变化对风媒孑遗植物进化史影响的一个案例研究。

Phylogeography of Pterocarya hupehensis reveals the evolutionary patterns of a Cenozoic relict tree around the Sichuan Basin.

Environmental factors such as mountain tectonic movements and monsoons can enhance genetic differentiation by hindering inter- and intra-specific gene flow. However, the phylogeographic breaks detected within species may differ depending on the different molecular markers used, and biological traits may be a major confounding factor. Pterocarya hupehensis is a vulnerable relict species distributed throughout the Sichuan Basin. Here, we investigated the phylogeographic patterns and evolutionary history of P. hupehensis using chloroplast DNA and restriction site-associated DNA sequencing data from 18 populations around the Sichuan Basin. The 24 chloroplast haplotypes separated into western and eastern lineages at approximately 16.7 Mya, largely coincident with a strengthening of the East Asian monsoon system during the early to middle Miocene. Both cpDNA and nuclear DNA datasets consistently identified distinct western and eastern lineages whose phylogeographic break conformed to the boundary of the Sino-Himalayan and Sino-Japanese forest sub-kingdoms. However, in contrast to the nuclear gene data, the cpDNA data revealed further divergence of the eastern lineage into northern and southern groups along the Yangtze River, a result that likely reflects differences in the extent of pollen vs seed dispersal. During the temperature decline in the penultimate (Riss) glacial period of the Pleistocene epoch, P. hupehensis experienced a genetic bottleneck event, and ecological niche modeling suggests that a subsequent population expansion occurred during the last interglacial period. Our findings not only establish a basis for conservation of this species, but also serve as a case study for the effects of geography and climate change on the evolutionary history of wind-pollinated relict plants.
