Metabolite data mapped on plant central metabolism. The metabolic network of the potato tuber was user-generated in VANTED. Metabolite profiling data of wildtype potato (Solanum tuberosum) tubers, and tubers expressing a yeast invertase either in an inducible or constitutive manner  was mapped onto the network. Each node represents a metabolite, connected by solid and dashed lines that represent single and lumped enzyme reactions, respectively. Data are means +/- standard error of the mean (SEM) of six independent plants. Values significantly different from the wildtype control as determined by an unpaired t-test (p < 005) were automatically marked with an asterisk. The bars in each diagram from left to right represent the values for the wildtype control (red), six inducible invertase lines, and one constitutive invertase line (light pink). The picture was created in VANTED and saved as a PNG file.
