Fig. 6From: Environmentally-driven gene content convergence and the Bacillus phylogenySignificant association between the natural environment and the COG-based clustering groups. The p-values were calculated based on the hypergeometric distribution of the groups obtained from the hierarchical clustering with COGs. The significant associations are indicated by black squares.
