Figure 7From: Analysis of genomic rearrangements, horizontal gene transfer and role of plasmids in the evolution of industrial important Thermus speciesHorizontal gene exchange between phyla and species. Every node represents one genomic island. Links between nodes indicate a significant compositional similarity between sequences of these genomic islands. A) Colour code indicates phyla of host organisms where the genomic islands were detected. B) Grey scale indicates a relative time of insertion of genomic islands into chromosomes of host organisms. As lighter the colour, as elder the insertion.Back to article page
