In the cyanobacterium Synechococcus 6301 two photosystem II complexes compete for excitation energy from the same phycobilisome in a statistical pigment bed organization of the light‐harvesting antenna. Incubation of intact cells at 0°C causes reversible dissociation of one photosystem II complex from the phycobilisome. Allophycocyanin‐B is proposed to link the two core‐cylinders of the phycobilisome in the excitation energy transfer pathway.
