By Christine H. Foyer and Graham Noctor Abstract Rising CO2 concentrations and their effects on plant productivity present challenging issues. Effects on the photosynthesis/photorespiration balance and changes in primary metabolism are known, caused by the competitive interaction of CO2 and O2 at the active site of ribulose-1,5-bisphosphate carboxylase/oxygenase. However, impacts on stress resistance are less … Continue reading Redox Homeostasis and Signaling in a Higher-CO2 World
