Gene organization of the PGC of AP64 in comparison with Proteobacteria and Firmicutes. Genome data were referenced for the PGC composition: R. capsulatus SB1003 (GenBank accession no. CP001312), R. gelatinosus IL144 (GenBank accession no. AP012320), and H. modesticaldum Ice1 (GenBank accession no. CP000930). bch (green), bacteriochlorophyll biosynthesis genes; puh (pink), genes encoding reaction center assembly proteins; puf (red), genes encoding reaction center proteins; crt (brownish yellow), carotenoid biosynthesis genes; gray, photosynthesis nonrelated genes or hypothetical ORFs.
