Key Process in Photosynthesis Likely Evolved Before Oxygen

A team of researchers, including Berkeley Lab earth scientist Bob Buchanan, has discovered that a regulatory process that turns on photosynthesis in plants at daybreak likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available. The research opens new scientific areas in the fields of evolutionary biology and microbiology. The work also has broad societal implications as it allows scientists to better understand the production of natural gas and it sheds light on climate change, agriculture and human health. More>
