Scientists are aimed to resolve various unsolved mysteries of the photosynthetic process that is utilized by various photosynthetic organisms and plants without experiencing damage. A photochemist at Arizona State University has found that photosynthetic organisms tuned their light-harvesting machinery to suit the desired wavelength or intensity of light. A plant biochemist at the University of California, Berkeley, finds that a large proportion of a genome of a photosynthetic organism is devoted to photosynthesis, while various genes make proteins that are involved in the global assembly and regulation of the photosynthetic process. A research group at the Free University of Berlin in collaboration with the Berlin Technical University report about the improved-resolution structures of a protein complex called photosystem II (PSII), a photosynthetic pigment.
