An eco‐evolutionary optimality model explains the acclimated temperature response of photosynthesis

Summary The optimal temperature of photosynthesis ( T opt ) generally increases with plant growth temperature. Changes in T opt are associated with changes in the maximum carboxylation capacity at 25°C ( V cmax25 ) and the maximum electron transport rate at 25°C ( J max25 ). The ratio between J max25 and V cmax25 declines with warming. Accurate representation of leaf‐level photosynthetic responses to temperature is essential for realistic projections of the terrestrial carbon cycle and its respo
