Figure 8. Consecutive steps of kaempferol biosynthesis pathways in Arabidopsis and maize stigmas.

(1)–(7) present the significant DEGs that encoded the enzymes, enzymes and substrates that catalyze consecutive steps, thereby constructing a metabolic route for kaempferol biosynthesis from L-phenylalanine in Arabidopsis and maize stigmas. EC numbers of enzyme were marked by red, enzymes were marked by pink, metabolic product were marked by blue, significant DEGs encoded enzymes were marked by black.
