FIG. 3.

The structure of the photosynthetic gene cluster of T. roseopersicina compared to those of Rhodobacter capsulatus (1) and Rubrivivax gelatinosus (10). Genes and ORFs are represented as arrows pointing in the direction of their transcription. Solid arrows indicate the puf genes, coding for the reaction center and light-harvesting center; stippled arrow symbolize the gene of the reaction center H subunit (puhA). The hatched and gray arrows stand for ORFs assigned to bacteriochlorophyll and carotenoid biosynthesis, respectively. Genes showing unusual locations in T. roseopersicina are labeled with asterisks. Open arrows indicate ORFs with unknown functions.
