*Mutated genes were assigned to one of the following functional categories: cell wall, DNA replication/repair (DNA), post-translational modification (PTM), RNA biogenesis, regulation, transport, transposase, or hypothetical. Number (No.) and frequency (%) of each functional category within strains or in total gene number are shown.
