Recently completed whole-genome sequencing projects marked the transition from gene-based phylogenetic studies to phylogenomics analysis of entire genomes. We developed an algorithm MGRA for reconstructing ancestral genomes and used it to study the rearrangement history of seven mammalian genomes: human, chimpanzee, macaque, mouse, rat, dog, and opossum. MGRA relies on the notion of the multiple breakpoint graphs to overcome some limitations of the existing approaches to ancestral genome reconstructions. MGRA also generates the rearrangement-based characters guiding the phylogenetic tree reconstruction when the phylogeny is unknown.
最近完成的全基因组测序项目标志着从基于基因的系统发育研究向对整个基因组进行系统发育基因组学分析的转变。我们开发了一种用于重建祖先基因组的算法MGRA,并使用它来研究七个人类、黑猩猩、猕猴、小鼠、大鼠、狗和负鼠的哺乳动物基因组的重排历史。MGRA依靠多重断点图的概念来克服现有祖先基因组重建方法的一些局限性。当系统发育未知时,MGRA还会生成指导系统发育树重建的基于重排的特征。
