  • a Gene number from the Pseudomonas genome project (http://www.pseudomonas.com).

  • b Boldface type indicates genes or gene products previously reported to be controlled by quorum sensing. RND, resistance-nodulation-cell division; FAD, flavin adenine dinucleotide.

  • c Maximum changes (fold) in gene expression (rounded to two significant figures) in the signal generation mutant in the presence of the signal(s) indicated compared with the absence of signal and in the wild-type P. aeruginosa strain compared with the receptor mutant. The values in parentheses are the OD600 at which the earliest change of ≥2.5-fold was observed (for the signal generation mutant both time courses were considered). NC, no change.

  • d There is a las-rhl box-like sequence with an HI of ≥10 and <13.

  • e There is a las-rhl box-like sequence with an HI of <10.

  • f The transcript levels for lasI and rhlI were close to the background level in the signal generation mutant due to the disruption of both loci by insertional mutagenesis.

  • g The GeneChip probes for PA4210 to PA4216 are identical to those for PA1899 to PA1905. Although the sequences for the genes in these two clusters are almost identical, the region upstream of PA4210 contains a las-rhl box-like sequence, but the region upstream of PA1899 does not.
