Evolution of C 4 plants: a new hypothesis for an interaction of CO 2 and water relations mediated by plant hydraulics
Open accessAbstract
C 4 photosynthesis has evolved more than 60 times as a carbon-concentrating mechanism to augment the ancestral C 3 photosynthetic pathway. The rate and the efficiency of photosynthesis are greater in the C 4 than C 3 type under atmospheric CO 2 depletion, high light and temperature, suggesting these factors as important selective agents. This hypothesis is consistent with comparative analyses of grasses, which indicate repeated evolutionary transitions from shaded forest to open habitats. However, such environmental transitions also impact strongly on plant–water relations. We hypothesize that excessive demand for water transport associated with low CO 2 , high light and temperature would have selected for C 4 photosynthesis not only to increase the efficiency and rate of photosynthesis, but also as a water-conserving mechanism. Our proposal is supported by evidence from the literature and physiological models. The C 4 pathway allows high rates of photosynthesis at low stomatal conductance, even given low atmospheric CO 2 . The resultant decrease in transpiration protects the hydraulic system, allowing stomata to remain open and photosynthesis to be sustained for longer under drying atmospheric and soil conditions. The evolution of C 4 photosynthesis therefore simultaneously improved plant carbon and water relations, conferring strong benefits as atmospheric CO 2 declined and ecological demand for water rose.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
