CO2-induced Benefits to Plant Water Use Efficiency – Video

As the atmosphere’s concentration of carbon dioxide (CO2) continues to rise in the years and decades ahead, plants will become ever-more efficient in their use of water thanks to incredible physiological changes brought about by this important trace gas. In short, they will need less water to produce the same or an even greater amount of biomass, which transformation holds significant ramifications for future plant drought resistance and global food production.
