Changes in grain protein and amino acids composition of wheat and rice under short‐term increased [CO₂] and temperature of canopy air in a paddy from East China

Summary Projected global climate change is a potential threat for food security. Both rising atmospheric CO 2 concentrations ([CO 2 ]) and temperatures have significant impacts on crop productivity, but the combined effects on grain quality are not well understood. We conducted an open‐air field experiment to determine the impacts of elevated [CO 2 ] (E‐[CO 2 ], up to 500 μmol mol −1 ) and warming (+2°C) on grain yield, protein and amino acid...
