From: Pangenome-wide and molecular evolution analyses of the Pseudomonas aeruginosa species
Functional annotation of the pangenome according to gene family categorization. Two Venn diagrams are presented, indicating the functional annotation at the orthology level (left diagram) and molecular pathway level (right diagram) for the three different categories established in concordance with gene frequency across strains. The redundancy of functions was predominantly at the pathway level and permitted to discern distinctive elements for each gene category. Those distinctive pathways are listed in Table 2
