Fig. 4From: A genetically and functionally diverse group of non-diazotrophic Bradyrhizobium spp. colonizes the root endophytic compartment of Arabidopsis thalianaPCoA on dissimilarities matrix shows that the Bradyrhizobium sp. MOS strains are functionally diverse. Plotted are the first two principal coordinates, which explain 20% and 11%, respectively. Each circle in the plot represents one functional profile. Green: strains containing the symbiotic island; orange: strains only possessing the nitrogen fixation gene cluster; red: strains lacking the symbiotic island; black: Bradyrhizobium sp. MOS strains, also lacking this islandBack to article page
