Abstract

The Sui people living in Guizhou province have a unique ethnic culture and population history due to their long‐time isolation from other populations. To investigate the genetic structure of Sui populations in different regions of Guizhou, we genotyped 89 individuals from four Sui populations using genome‐wide single nucleotide polymorphisms arrays. We analyzed the data using principal component analysis, ADMIXTURE analysis, f‐statistics, qpWave/qpAdm, TreeMix analysis, fineSTRUCTURE, and GLOBETROTTER. We found that Sui populations in Guizhou were genetically homogeneous and had a close genetic affinity with Tai‐Kadai‐speaking populations, Hmong‐Mien‐speaking Hmong, and some ancient populations from southern China. The Sui populations could be modeled as an admixture of 33.5%–37.9% of Yellow River Basin farmer‐related ancestry and 62.1%–66.5% of Southeast Asian‐related ancestry, indicating that the southward expansion of northern East Asian‐related ancestry influenced the formation of the Tai‐Kadai‐speaking Sui people. Future publications of more ancient genomics in southern China could effectively provide further insight into the demographic history and population structure of the Sui people.

中国西南地区隋代种群的遗传形成
生活在贵州省的隋族由于长期与其他人群隔绝,形成了独特的民族文化和人群历史。为了研究贵州不同地区水族人群的遗传结构,我们使用全基因组单核苷酸多态性阵列对来自四个水族人群的 89 个个体进行了基因分型。我们使用主成分分析、ADMIXTURE分析、f统计、qpWave/qpAdm、TreeMix分析、fineSTRUCTURE和GLOBETROTTER对数据进行了分析。我们发现,贵州的水族种群在遗传上具有同质性,并与讲傣语的噶代种群、讲苗语的苗族以及中国南方的一些古老种群有着密切的遗传亲缘关系。隋人的祖先中,33.5%-37.9%与黄河流域农民有关,62.1%-66.5%与东南亚有关,这表明东亚北部相关祖先的南下影响了说傣语的隋人的形成。未来在中国南方发表更多的古代基因组学研究成果,可以有效地进一步了解隋人的人口历史和人口结构。

期刊介绍: Journal of Systematics and Evolution (JSE, since 2008; formerly Acta Phytotaxonomica Sinica) is a plant-based international journal newly dedicated to the description and understanding of the biological diversity. It covers: description of new taxa, monographic revision, phylogenetics, molecular evolution and genome evolution, evolutionary developmental biology, evolutionary ecology, population biology, conservation biology, biogeography, paleobiology, evolutionary theories, and related subjects.
