Elevated [CO₂] effects on crops: Advances in understanding acclimation, nitrogen dynamics and interactions with drought and other organisms

Future rapid increases in atmospheric CO 2 concentration [ CO 2 ] are expected, with values likely to reach ~550 ppm by mid‐century. This implies that every terrestrial plant will be exposed to nearly 40% more of one of the key resources determining plant growth. In this review we highlight selected areas of plant interactions with elevated [ CO 2 ] (e[ CO 2 ]), where recently published experiments challenge long‐held, simplified views. Focusing...
