  1. a Fold changes represent the ratio of the expression levels in the comparison of P. aeruginosa Δ::tn7TLACpak or Δ::tn7TLAC, respectively, and PAO1::tn7TLAC. Minus (-) sign indicates a decreased expression in Δ strains;b Fold change not significantly different from PAO1::tn7TLAC (P > 0.05); + IPTG - induction of expression with 1 mM IPTG
