Effects of ambient CO2 concentration (400 μmol mol−1) and elevated CO2 concentration (800 μmol mol−1) treatments on fatty acid levels in soybean seeds. The asterisk indicates a significant difference between ambient and elevated CO2 treatments (P < 0.05). Data are mean ± S.D. (n = 5 or 6); experiments were repeated three times.
