Primary events in photosynthetic (PS) acclimation to elevated CO2 concentration ([CO2])
occur at the molecular level in leaf mesophyll cells, but final growth response to [CO2] …

This paper reviews two decades of effort by the scientific community in a search for
predictive understanding of plant responses to elevated [CO2]. To evaluate the progress of …

Plants grown at elevated pCO2 often fail to sustain the initial stimulation of net CO2 uptake
rate (A). This reduced, acclimated, stimulation of A often occurs concomitantly with a …

Long‐term exposure of plants to elevated CO2 often leads to downward photosynthetic
acclimation. Nitrogen (N) deficiency could potentially exacerbate this response by reducing …

Rising atmospheric CO2 concentration (Ca) may alter two components (sensitivity and
acclimation) of global photosynthetic carbon influx into terrestrial ecosystems (PG). Most …

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 …

Upon exposure to altered levels of CO2, plants express a variety of acclimations to CO2
directly, over and above acclimations to indirect changes in temperature and water regimes …

The concentration of atmospheric CO2 has increased from below 200 μl l− 1 during last
glacial maximum in the late Pleistocene to near 280 μl l− 1 at the beginning of the Holocene …

Background Process-based ecophysiological crop models are pivotal in assessing
responses of crop productivity and designing strategies of adaptation to climate change …

Few of the most common assumptions used in models of responses of plants and
ecosystems to elevated CO2 and climate warming have been tested under realistic life con …
