Similar photosynthetic but different yield responses of C₃ and C₄ crops to elevated O₃.

ABSTRACT: The deleterious effects of ozone (O₃) pollution on crop physiology, yield, and productivity are widely acknowledged. It has also been assumed that C₄ crops with a carbon concentrating mechanism and greater water use efficiency are less sensitive to O₃ pollution than C₃ crops. This assumption has not been widely tested. Therefore, we compiled 46 journal articles and unpublished datasets that reported leaf photosynthetic and biochemical traits, plant biomass, and yield in five C₃ crops (chickpea, rice, snap bean, soybean, and wheat) and four C₄ crops (sorghum, maize, Miscanthus × giganteus, and switchgrass) grown under ambient and elevated O₃ concentration ([O₃]) in the field at free-air O
