Fig. 1From: Identification of constraints influencing the bacterial genomes evolution in the PVC super-phylumComparison of the genome contents in the different habitats. The quantity of genes common to all habitats (common genes), and their functions, are indicated in the center of the flower. Genes specific to each habitat and genes shared by different habitats are represented by the different petals. The clouds represent the ORFans percentages in genomes. The width of the petals and the clouds is proportional to the quantity of specific genes and percentage of ORFans, respectively. The functional distribution of common, shared and specific genes is presented in the tableBack to article page
