The floral volatile benzenoid/phenylpropanoid pathway in petunia. The shikimate pathway (dark grey) concludes with the formation of chorismate. CHORISMATE MUTASE catalyzes the rearrangement of chorismate to prephenate, directing the flux of metabolites to the production of phenylalanine and tyrosine. From the phenylpropanoid backbone (light grey), FVBP production consists of three main branch-points; phenylalanine, trans-cinnamic acid, and ferulic acid. Floral volatile compounds derived from each branch-point are highlighted in pink and known FVBP genes are abbreviated at the appropriate enzymatic positions. Enzymes are in red. Solid red arrows indicate established biochemical reactions. Multiple arrows indicate multiple biochemical steps. Dashed arrows indicate possible biochemical reactions.
