Abstract
The comparative analysis of genomic characteristics and single-nucleotide polymorphism patterns from large fragments borne on different replicons of Sinorhizobium spp. genomes clearly demonstrate that DNA recombination among closely related bacteria is a major event in the diversification of this genome, especially in pSymA, resulting in mosaic structure.
摘要
对中华根瘤菌属基因组不同复制子上大片段的基因组特征和单核苷酸多态性模式进行的比较分析清楚地表明，密切相关细菌之间的DNA重组是该基因组多样化的主要事件，尤其是在共生质粒A（pSymA）中，导致了镶嵌结构。
