Hierarchical clustering of 10 biomining bacteria according to CIB values grouped by COG category.

<p><b>A.</b> Conserved genes, <b>B.</b> Unique genes. For each strain, the mean value of CIB was calculated for genes (both conserved and unique) within each COG category. The strains were then hierarchically clustered using average linkage with the Pearson product correlation coefficient measuring the distance between the vectors of mean CIB per COG category. The color bar ranges from green (low CIB, 0.0) to red (high CIB, 0.5).
