Altering the process of photosynthesis

Photosynthesis, the process by which plants turn sunlight into food, is crucial to crop production and our food systems. What if we could increase the yield of food crops by improving photosynthesis? Stephen Long, Professor of Crop Sciences and Plant Biology at the University of Illinois at Urbana-Champaign, joined Andrea Vasquez in a Google Hangout to discuss the genetic altering of plants.
