论生物基因组的起源和进化

On the Origin and Evolution of Organic Genomes

通过分析核（类核）基因组、线粒体基因组和叶绿体基因组的大小与结构，发现这三种基因组都有“小基因组”和“大基因组”的形式及与之对应的结构特点．认为它们各自的祖先都是通过分别与“小基因组”和“大基因组”相应的两种途径进化成为现代核（类核）基因组、线粒体基因组和叶绿体基因组．发展了生物基因组起源和进化的统一模式．

The sizes and structural features of nuclear(nucleoid) genomes, mitochondrial genomes and chloroplast genomes were analyzed, revealing that these three kinds of genomes all have the “small genome” type and the “large genome” type with corresponding structural features. It is concluded that the three kinds of genomes would have evolved according to the “small genome” and the “large genome” evolutionary scenarios. A general pattern for the origin and evolution of organic genomes has been developed.
