Different type of photosynthesis may save temperate crops from climate change

Different type of photosynthesis may save temperate crops from climate change

Science
Oct. 23 (UPI) -- In many places, climate change is expected to bring hotter, drier weather. In a new study, published Friday in the journal The Plant Cell, scientists considered whether an alternative mode of photosynthesis, might yield more heat-tolerant and drought-resistant plants. Most plants in arid and semi-arid environs use a photosynthesis method called Crassulacean acid metabolism, or CAM. Alternatively, plants in temperate environs, including crops, rely on a photosynthesis method called C3 carbon fixation. Advertisement Plants using C3 carbon fixation absorb CO2 through their leaves' stomatal pores. The daytime process allows C3 plants to immediately convert sunlight into food. When conditions are especially hot and dry, C3 metabolism causes plants to lose too much water. Conve...
