abstract = {Generalised dose–response curves are essential to
understand how plants acclimate to atmospheric CO2. We
carried out a meta-analysis of 630 experiments in which C3
plants were experimentally grown at different [CO2] under
relatively benign conditions, and derived dose–response
curves for 85 phenotypic traits. These curves were
characterised by form, plasticity, consistency and
reliability. Considered over a range of 200–1200 µmol
mol−1 CO2, some traits more than doubled (e.g. area-based
photosynthesis; intrinsic water-use efficiency), whereas
others more than halved (area-based transpiration). At
current atmospheric [CO2], $64\%$ of the total stimulation
in biomass over the 200–1200 µmol mol−1 range has
already been realised. We also mapped the trait responses of
plants to [CO2] against those we have quantified before for
light intensity. For most traits, CO2 and light responses
were of similar direction. However, some traits (such as
reproductive effort) only responded to light, others (such
as plant height) only to [CO2], and some traits (such as
area-based transpiration) responded in opposite directions.
This synthesis provides a comprehensive picture of plant
responses to [CO2] at different integration levels and
offers the quantitative dose–response curves that can be
used to improve global change simulation models.},
