Photosynthesis fix may enhance food production

Researchers are trying to replicate in food crops a change they made to tobacco plants that repaired a defect in photosynthesis in which plants inadvertently took hold of oxygen molecules instead of carbon dioxide, forcing the plant to use valuable energy clearing up that mistake. Researchers have tried to reroute the toxic byproducts resulting from photorespiration and to help plants adapt more easily to variable light levels, according to findings published in Science.
