Figure 3. Flavonoid biosynthesis pathway and tissue-specific molecule abundance visualized using Cytoscape.

Parallelogram: transcript; rectangle: protein; ellipse: metabolite; triangle: reaction node. Blue edges with circle at the tip: catalysis. Black edges with Delta at the tip: metabolic reaction. Turquoise edges: translation. Transcript node in bold: existence of an Affymetrix (Vitis Vinifera (Grape) Genome Array) probeset. Red: over abundant in seed; magenta: over abundant in skin; green: over abundant in pulp; orange: over abundant in seed and skin. Insert box at the upper right represents a zoom-in of an area of the network showing the different molecule types.
