Relative to expression in strain PAO1. Values are means from two independent experiments, each including duplicate determinations. Genes mexY and PA1797 are considered as significantly up-regulated (in boldface) when their respective expression is at least four-fold higher than those in PAO1.

PAO1-like sequence.

PA14- and LESB58-like sequence.

nd, not determined; wt, wild-type sequence.
