Figure 4From: A U-system approach for predicting metabolic behaviors and responses based on an alleged metabolic reaction networkMetabolic reaction network of Arabidopsis focused in this study. Green zone, aromatic amino acid biosynthesis, indole GSL biosynthesis, histidine biosynthesis and leucine and valine biosynthesis; gray zone, purine and pyrimidine biosynthesis; pink zone, glycolysis pathway, TCA cycle and pentose phosphate pathway; yellow zone, aspartate-family amino acid biosynthesis, proline biosynthesis, lysine degradation, methionine salvage pathway, aliphatic GSL biosynthesis. The number i in square boxes indicate the metabolite numbers arbitrarily given for simulations (Supplementary Model - additional file 2).Back to article page
