FIG. 5.

Comparison of the Pf4 genome with the genome of Pf1. Genes are indicated as follows: blue, homologous genes found in both Pf1 and Pf4; red, genes occurring only in Pf4; green, new genes or ORFs identified in this study that occur only in Pf4; grey, genes found only in Pf1 and not in Pf4. The numbers above the Pf1 genes are the ORF numbers as presented in the published genome sequence of Pf1 (24). The numbers below the Pf4 genes are gene numbers from the published P. aeruginosa genome sequence (54).
