Figure 3: Changes in metabolism inside plant cells under in silico CO2 elevation. Heat map plot shows the metabolic changes inside plant cells under in silico CO2 elevation: (a) metabolite concentrations and (b) fluxes through enzymes in the starch biosynthesis pathway. The colour intensity and tones represent magnitude and direction of metabolic changes, respectively; magnitude of change ranging from grey (reference) to red (more deviation from reference in positive direction) or green (more deviation from reference in negative direction). Changes from red to green as shown in the figure indicate the presence of a convex point, or a state at which metabolism conversely changes the direction of biochemical reactions within the pathway. |
