Cluster sizes in number of genes (Y-axis, gray bars) for four representative species, (A) Campylobacter jejuni, (B) Methanococcus janaschii, (C)Mycoplasma pneumoniae, and (D) Treponema pallidum, compared to the average number of best hits (BeTs) for each cluster (Y-axis, black bars) in all other completely sequenced bacterial genomes.
