Review:  New insights into the cellular mechanisms of plant growth at elevated atmospheric carbon dioxide (Plant Cell Environ) $

Elevated CO2 (eCO2) encourages plant growth through increased photosynthetic rates and lower stomatal conductance.  However, eCO2 also has knock-on effects on plant secondary metabolism, which can also affect plant growth.  In this review, Gamage et al explore these ‘post-photosynthetic’ effects…

Unexpected reversal of C3 versus C4 grass response to elevated carbon dioxide during a 20-year field experiment (Science) $

It is widely accepted that the growth of C3 plants responds more to elevated CO2 (eCO2) than that of C4 plants, since photosynthesis in C3 plants is more limited by the current atmospheric CO2:O2 ratio due to the oxygenase activity of Rubisco.  This has been established empirically in short-term eCO2…
