Missing link in algal photosynthesis found, offers opportunity to improve crop yields

Photosynthesis is the natural process plants and algae utilize to capture sunlight and fix carbon dioxide into energy-rich sugars that fuel growth, development, and in the case of crops, yield. Algae evolved specialized carbon dioxide concentrating mechanisms (CCM) to photosynthesize much more efficiently than plants. This week, in the journal Proceedings of the National Academy of Sciences, a team from Louisiana State University (LSU) and the University of York report a long-time unexplained step in the CCM of green algae—which is key to develop a functional CCM in food crops to boost productivity.
