Total number of SNPs, nucleotide diversity (mean θ_π) and mean <i>D_T</i> for all data and for gene regions separated by species and replicon.

Data are only from genes for which >90% of the sites have unambiguous base calls from ≥80% of the strains and were not identified as recently transferred between S. meliloti and S. medicae.本数据集仅收录满足以下条件的基因：该基因90%以上的位点在至少80%的菌株中均得到明确的碱基调用结果，且未被鉴定为苜蓿根瘤菌（Sinorhizobium meliloti，缩写S. meliloti）与中慢生根瘤菌（Sinorhizobium medicae，缩写S. medicae）之间近期发生转移的基因。
