Abstract

The now-emerging mitochondrial DNA (mtDNA) population genomics provides information for reconstructing a well-resolved mtDNA phylogeny and for discerning the phylogenetic status of the subcontinentally specific haplogroups. Although several major East Asian mtDNA haplogroups have been identified in studies elsewhere, some of the most basal haplogroups, as well as numerous minor subhaplogroups, were not yet determined or fully characterized. To fill the lacunae, we selected 48 mtDNAs from >2,000 samples across China for complete sequencing that cover virtually all (sub)haplogroups discernible to date in East Asia. This East Asian mtDNA phylogeny can henceforth serve as a solid basis for phylogeographic analyses of mtDNAs, as well as for studies of mitochondrial diseases in East and Southeast Asia.

摘要

如今新兴的线粒体DNA(mtDNA)群体基因组学为重建解析度高的mtDNA系统发育树以及识别次大陆特异性单倍群的系统发育地位提供了信息。尽管在其他地方的研究中已经鉴定出了几个主要的东亚mtDNA单倍群,但一些最基础的单倍群以及众多的小亚单倍群尚未确定或得到充分表征。为了填补这些空白,我们从中国各地的2000多个样本中挑选了48个mtDNA进行全序列测序,这些样本几乎涵盖了迄今为止在东亚可识别的所有(亚)单倍群。此后,这个东亚mtDNA系统发育树可作为mtDNA系统地理学分析以及东亚和东南亚线粒体疾病研究的坚实基础。
