a
Genes are identified by ORF designation, gene name, and protein description or known metabolic pathway (http://www.pseudomonas.com).
b
The magnitude and direction of gene expression change are indicated for PAO-JP2 grown with exogenous autoinducers (1 μM 3O-C12-HSL and 2 μM C4-HSL) compared to PAO-JP2 cultures grown aerobically in modified FAB. The values are the values for the first gene in the known or probable operons.
