TL;DR: Providing a future energy supply that is secure and CO_2-neutral will require switching to nonfossil energy sources such as wind, solar, nuclear, and geothermal energy and developing methods for transforming the energy produced by these new sources into forms that can be stored, transported, and used upon demand.
Journal ArticleDOI
Improved temperature response functions for models of Rubisco‐limited photosynthesis
TL;DR: The results represent an improved ability to model leaf photosynthesis over a wide range of temperatures necessary for predicting carbon uptake by terrestrial C3 systems.
Journal ArticleDOI
Improved temperature response functions for models of Rubisco-limited photosynthesis: In vivo Rubisco enzyme kinetics
Journal ArticleDOI
Temperature Response of Mesophyll Conductance. Implications for the Determination of Rubisco Enzyme Kinetics and for Limitations to Photosynthesis in Vivo

TL;DR: Despite an exponential rise with temperature, g m does not keep pace with increased capacity for CO2 uptake at the site of Rubisco, showing that transfer of CO2 from the intercellular air space to Rubisco is a very substantial limitation on photosynthesis, especially at high temperature.
Journal ArticleDOI
Rubisco activase - Rubisco's catalytic chaperone.
TL;DR: In conclusion, Rubisco activase is one of a new type of chaperone, which in this case functions to promote and maintain the catalytic activity of Rubisco, and its physiological importance is reinforced by recent studies indicating that it plays a vital role in the response of photosynthesis to temperature.
