  • 摘要: 虽然来自线粒体的分子证据已清晰地揭示家驴来源于两个不同的母系支系,然而目前仍不清楚这两个支系具体的扩散历史。因此,本研究采集了171个来自中亚、东亚和非洲的家驴样品,并整合了536条已公布的涵盖了欧洲、亚洲和非洲的线粒体序列,在全球视野下分析了这两个支系的多个群体特征的异同。结果表明,无论是线粒体全基因组还是D-loop区序列,均能将这两个支系明显地区分开来。其中支系I在8000多年前经历了群体增长,形成了一个复杂的单倍型网络结构。相比之下,支系II的种群大小一直维持相对稳定,呈现较为简单的单倍型网络结构。尽管这两个支系在欧亚大陆的分布频率几乎相等,但它们在起源地非洲大陆的大部分地区却表现出明显的地理结构:支系I主要分布在撒哈拉以南,而支系II则主要分布在非洲大陆的东部和北部海岸。此外,根据遗传多样度衰减程度亦提示支系I和II在进入中国后的扩散路线也是不同的。综上所述,多个群体遗传特征差异均表明,从母系遗传角度看,家驴的两个支系I和II来自不同的驯化事件,可能分别对应了游牧民族对撒哈拉沙漠荒漠化的适应和古代文明与贸易在非洲东北部的交流和扩张。

     

    Abstract: Molecular studies on donkey mitochondrial sequences have clearly defined two distinct maternal lineages involved in domestication. However, domestication histories of these two lineages remain enigmatic. We therefore compared several population characteristics between these two lineages based on global sampling, which included 171 sequences obtained in this study (including Middle Asian, East Asian, and African samples) plus 536 published sequences (including European, Asian, and African samples). The two lineages were clearly separated from each other based on whole mitochondrial genomes and partial non-coding displacement loop (D-loop) sequences, respectively. The Clade I lineage experienced an increase in population size more than 8 000 years ago and shows a complex haplotype network. In contrast, the population size of the Clade II lineage has remained relatively constant, with a simpler haplotype network. Although the distribution of the two lineages was almost equal across the Eurasian mainland, they still presented discernible but complex geographic bias in most parts of Africa, which are known as their domestication sites. Donkeys from sub-Saharan Africa tended to descend from the Clade I lineage, whereas the Clade II lineage was dominant along the East and North coasts of Africa. Furthermore, the migration routes inferred from diversity decay suggested different expansion across China between the two lineages. Altogether, these differences indicated non-simultaneous domestication of the two lineages, which was possibly influenced by the response of pastoralists to the desertification of the Sahara and by the social expansion and trade of ancient humans in Northeast Africa, respectively.
