27 40 a significant reduction in the activation state of Rubisco occurs for Populus deltoides and Populus balsamifera as leaf temperature increases from 27 to 40 °C. A greater reduction occurs for Populus balsamifera Rubisco, such that its activation state is 10% points less than that for Populus deltoides Rubisco at 36 and 40 °C Populus balsamifera

General Information

General Information Comment Organism
physiological function Populus deltoides exhibits a higher photosynthetic assimilation at 33-40°C compared to that for Populus balsamifera. This is due to a higher activation state of Rubisco and correlated with a higher ATPase activity of Rubisco activase in Populus deltoides Populus deltoides
