Transgenic rice expressing five C4 enzymes shows in vivo operation of the four core C4 reactions, establishing a functional carbon-concentrating flux framework.
- Why it matters: C4 photosynthesis is more efficient than C3, and introducing it into rice could increase yield by 50%, but prior work lacked evidence for later-cycle flux.
- What they did: The team created new transgenic rice lines and protocols to detect C4-cycle activity by tracking CO2 fixation into C4 acids, decarboxylation, Rubisco refixation, and C3 regeneration.
- The result: These measurements demonstrate that the four core C4 reactions are operating in rice, enabling progress toward a complete, functional carbon-concentrating mechanism.
