Figure 3.

The pan-genome of Sinorhizobium. The flower plots and Venn diagrams illustrate the number of shared and specific (accessory) genes based on clusters of orthologs. (a) Flower plot showing numbers of species-specific genes commonly found in each genome of each species (in the petals), and Sinorhizobium core orthologous gene number (in the center). (b) Flower plots showing numbers of unique orthologous genes in each S. meliloti strain (in the petals), and S. meliloti core orthologous gene number (in the center). (c) Flower plots showing numbers of unique orthologous gene in each S. medicae strain (in the petals), and S. medicae core orthologous gene number (in the center). (d) Venn diagram showing numbers of unique orthologous genes in each S. fredii strain, and S. fredii core orthologous gene number.
