Significant energy transfer from CpcG2-phycobilisomes to photosystem I in the cyanobacterium Synechococcus sp. PCC 7002 in the absence of ApcD-dependent state transitions.

Abstract excerpt

Hemidiscoidal phycobilisomes (PBS), the major light harvesting complexes of photosynthesis in most cyanobacteria, are composed of rods and cores, which are linked by the linker CpcG1 (L(RC)). Another type of PBS, CpcG2-PBS exits and their function in energy transfer has not been fully understood. We measured growth rates, absorption cross-sections and quantum efficiency of photosystem I in mutant strains of...
