Unlocking Rice's Potential: Redesigning Photosynthesis for Increased Yield
CO2-concentrating mechanisms in C4 plants require energy and proteins to increase CO2 supply to Rubisco during photosynthesis. The effectiveness of this mechanism is influenced by factors like overcycling, photorespiration, and CO2 diffusion. Comparisons show when C4 photosynthesis can be beneficial and the challenges of engineering it into C3 plants. The study discusses conditions where photosynthesis is CO2-limited and when rice could benefit from a CO2-concentrating mechanism.
