A putative metabolic map described the pathway including the floral scent metabolic pathway and lignin pathway during the degradation of anthocyanins in B. acuminata petals. The diagram shows the different pathways. The diagram summarizes the results of qRT-PCR, MALDI-TOF/TOF and GC-TOF-MS analyses. The dashed black arrows represent several consecutive enzymatic steps. The color of the box indicates the method by which they were identified. The red arrow represents up or down and the symbol with * in the picture is expressed as an important substance identified in the petals. Enzymes: SAMT, salicylic acid carboxyl methyltransferase; COMT, catechol O-methyl transferase; CCoA-OMT, caffeoyl-CoA O-methyl; OMT, Anthocyanin-O-methyl transferase. Genes: CHS, chalcone synthase; CHI, chalcone isomerase; F3′5′H, flavonoid 3′5′-hydroxylase.
