Responses of Metabolites in Soybean Shoot Apices to Changing Atmospheric Carbon Dioxide Concentrations
Effects of reversing the ambient and elevated CO2 treatments on metabolite levels in soybean apices. Sucrose (a) and Unk-21.03 (b) were measured in soybean apices using plants that were grown for a total of 24 d in the ambient (°) and elevated (●) CO2 treatments. Reciprocal transfers were performed 21 DAS by switching one-half the plants from ambient to elevated CO2 (Δ) and vice versa (▲). Values are means ± SE (n = 8).
