arthurgesslerIn our new paper we question the conventional understanding that #diffusional limitations of CO2 contribute to the reduction in #photosynthesis at high #temperatures. We suggest that #stomata and #mesophyll membranes could work strategically to facilitate #transpiration cooling and #CO2 supply, thus alleviating #heat #stress on leaf photosynthetic function, albeit at the cost of reduced #WateUseEfficiency.
