Divergent Control of Two Type VI Secretion Systems by RpoN in Pseudomonas aeruginosa

Sfa2 negatively controls H2-T6SS expression while H3-T6SS expression is Sfa-independent.
The expression of H3-T6SS left (A), H3-T6SS right (B), and H2-T6SS (C) after 6 hours of growth after 9 hours (A & B) or 7 hours (C) at 37°C in the WT strain (blue bars), in a PAO1sfa2 mutant (red bars), and in a PAO1sfa3 mutant (green bars). Expression is given in Miller units. Each experiment was done in triplicate and independently repeated three times; error bars indicate the standard deviation.
