Responses of Metabolites in Soybean Shoot Apices to Changing Atmospheric Carbon Dioxide Concentrations

Figure 4

Inverse relationship between Unk-21.03 and increasing partial pressures of atmospheric CO₂. (a) Plants were grown for 21 ds at four different partial pressures of CO₂ prior to analyzing for Unk-21.03. Values on the y-axis are integrated peak areas normalized by the mass of apical tissue in each sample. (b) The mass spectrum of Unk-21.03.
