Noting that copper (Cu) is "an essential micronutrient [that] plays a vital role in maintaining normal metabolism in higher plants," but that it "is toxic to plant cells at higher concentrations and causes the inhibition of plant growth or even death," Jia et al. (2007)1 grew a Japonica rice cultivar in control and Cu-contaminated soil for one full season at ambient and elevated atmospheric CO2 concentrations (370 vs. 570 ppm), while measuring leaf Cu concentrations at the tillering, jointing, heading and ripening stages of the crop.
