Phenylpropanoid biosynthesis pathway. Proteins (â–¡) and metabolites (o) with differential abundance involved in phenylpropanoid biosynthesis metabolism were mapped to the corresponding metabolic pathways in KEGG. Red indicates up-regulation; green indicates down-regulation; and yellow indicates no significant difference. The up-regulated proteins were beta-glucosidase [EC: 3.2.1.21] and cinnamyl-alcohol dehydrogenase [EC: 1.1.1.195], and the down-regulated proteins in this pathway were caffeic acid 3-O-methyltransferase [EC: 2.1.1.68] and caffeoyl-CoA O-methyltransferase [EC: 2.1.1.104]. The up-regulated metabolite was L-phenylalanine, and the down-regulated metabolite was 4-hydroxycinnamic acid
