Abstract Background Marine Synechococcus owe their specific vivid color ranging from blue-green to orange to their large extrinsic antenna complexes called phycobilisomes comprising a central allophycocyanin core and rods of variable phycobiliprotein composition. Three major pigment types can be defined depending on the major phycobiliprotein found in the rods phycocyanin phycoerythrin I or phycoerythrin II . Among strains containing both phycoerythrins I and II four subtypes can be distinguished based on the ratio of the two chromophores bound to these phycobiliproteins. Genomes of
