Soil and plant water relations determine photosynthetic responses of C3 and C4 grasses in a semi-arid ecosystem under elevated CO2
In a field study, LeCain et al. (pp. 41-52) show that acclimation in a C3 grass almost eliminates a direct photosynthetic response to elevated CO2, but enhances soil and plant water relations and improves seasonal carbon uptake in a C3 and a C4 grass.
