Identification of a gene needed to expand light harvesting in photosynthesis into the far-red-light spectrum provides clues to the development of oxygen-producing photosynthesis,an evolutionary advance that changed the history of life on Earth. "Knowledge of how photosynthesis evolved could empower scientists to design better ways to utilize light energy for the benefit of mankind," said Donald A. Bryant, and the Ernest C. Pollard Professor of Biotechnology and professor of biochemistry and molecular biology at Penn State University and the leader of the research team that made the discovery.
