A molecular model of the light-harvesting structure phycobilisome–photosystem II (right; cyan: phycobilisome, green: photosystem II). By determining the molecular structure of phycobilisome interacting with photosystem II, RIKEN researchers have found two pathways for energy transfer between the two structures. Credit: RIKEN SPring-8 Center RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in the journal Plant and Cell Physiology . Green is the color that most people associate with plants, microalgae life and natural environments. That's because most plants and microalgae use the green pigment chlorophyll to absorb sunlight. This absorbed visible light is converted into chemical energy, which plants use to power the process of photosynthesis.…
