  1. aStandard deviation was calculated using a sliding 1 kb window (see Additional data file 1). bClasses 1-4 refer to the confidence rating assigned to the predicted gene function, as previously described [7,22]. Class 1 genes are those whose function has been experimentally validated in P. aeruginosa. Class 2 genes are highly similar to genes whose functions have been validated in another organism. Class 3 genes have hypothesized functions based on limited similarity to other genes or structural/functional domains. Class 4 genes are open reading frames (ORFs) of unknown function. cStrain-specific regions with at least one ORF.
