Overall, the lessons that can be extracted from this simulation
study are: (1) acclimation of stomatal conductance to climate
change conditions results in a significant reduction of the expected
benefits of high CO2 in photosynthesis under light saturation; (2) a
potential acclimation of mesophyll conductance to CO2 besides gs
cannot be neglected when attempting to model photosynthesis in a
climate change scenario, as it roughly doubles the reduction which
occurs with acclimation of stomatal conductance alone
