Fig. 11

KEGG pathway: Differentially expressed genes and metabolites in arginine and proline metabolism. In the upper right corner of the figure, there are two legends, from top to bottom, for “gene” and “metabolite” respectively. The “gene” legend corresponds to the rectangles in the diagram, while the “metabolite” legend corresponds to the circles. The color intensity in both shapes indicates the expression level, with higher expression depicted as a deeper shade of red
