Comparative analysis of the common polysaccharide antigen (CPA) cluster. The CPA synthesis gene cluster could not be identified in most of the analysed Pseudomonas genomes. (A) Heatmap of results from a BLASTP search for homologous CPA biosynthesis enzymes in different predicted proteomes. P. aeruginosa PAO1 sequences were used as reference (e‐value cut‐off of 10−9). Phylogenetic tree shows the Euclidean distance calculated from the BLASTP identities. (B) Gene structure of the P. aeruginosa PAO1 and P. brassicacearum NFM421 CPA cluster and locus of putative ABC‐transporter subunit homologues in P. syringae pv. tomato DC3000 and P. cichorii JBC1. Colour indicates the respective gene hits in the genomes.
