Figure 5. Venn diagrams representing unique and overlapping gene regulation in PA2572 and PA2573 mutants.

Mutant strains were compared to the parental PAO1 strain during exponential growth phase (0.6–0.7 OD₆₀₀) in LB media. Genes were considered to have significant alteration in expression based on two-fold changes compared with wild-type. The numbers of genes regulated in an upward direction (A) and a downward direction (B) are shown.
