  • a Genes are identified by ORF designation and protein description (http://www.pseudomonas.com).

  • b Transcript detection of genes by using microarrays. P, present; A, absent; PL, present at low levels. A low level of transcript abundance was defined as a transcript abundance of less than 500 intensity units.

  • c A high coefficient of variation (CV) was defined as greater than 20%. NA, not applicable.
