我们首次利用线粒体控制区和ATPase6基因的序列对灰鲑属胸腺属（鲑科）的分子系统发育进行了深入研究。一套分析方法分别应用于每个基因和组合数据。结果表明，ATPase6基因在整个属中的平均分化率比完全控制区域快2.46倍。根据综合数据，四个主要的（内部）进化支在所有分析中都得到了高度支持，它们可能起源于上新世，代表了黑龙江盆地的两个不同的谱系，一个谱系在所有剩余的西伯利亚和蒙古流域，一个谱系对应于欧洲的灰鱼。在每个主要流域内，从额外的内部分支和末端分支中分离出的多个谱系强调了更新世水文动力学对西伯利亚生物多样性分布的复杂性和影响。(C) 2004爱思唯尔公司版权所有。
We present first insights into the molecular phylogeny of the grayling genus Thymallus (Salmonidae) using sequences from the mitochondrial control region and ATPase6 genes. A suite of analytical approaches were applied for each gene separately and for the combined data. The ATPase6 gene is shown to have a mean divergence rate across the genus of 2.46 times faster than the complete control region. Based on the combined data, four major (internal) clades, presumably originating in the Pliocene, were resolved with high support in all analyses and represented two distinct lineages in the Amur basin, one lineage in all remaining Siberian and Mongolian drainages, and one lineage corresponding to European grayling Thymallus thymallus. The resolution of multiple lineages, from both additional internal and terminal clades, within each major drainage basin underscores the complexity and effects that Pleistocene hydrological dynamics have had on the distribution of biodiversity in Siberia.
