Figure 3

Hierarchical clustering of Pearson correlation coefficients determined from the absence or presence of the individual protein families in each of the analysed genomes. The heatmap colours indicate the Pearson correlation coefficient among the strains: The colormap in the left corner illustrates the correlation values by colour, as well as the frequency of each correlation value. The colour bar shows the individual species of each particular strain: S. gordonii IE isolates (dark blue), S. gordonii oral isolates (light blue), S. sanguinis IE isolates (dark purple), and the S. sanguinis oral isolates (light purple).
