Terpenoid biosynthetic pathway. Terpenoid precursors (acetyl-CoA and pyruvate) enter the MVA pathway in the cytosol to produce sesquiterpenes or the MEP pathway in plastids to generate monoterpenes, diterpenes, and carotenoids. The enzymes and intermediates of both pathways are shown. DMAPP, dimethylallyl diphosphate; FPP, farnesyl diphosphate; FPPS, farnesyl pyrophosphate synthase; GGPP, geranylgeranyl pyrophosphate; GGPS, geranylgeranyl pyrophosphate synthase; GPP, geranyl diphosphate; GPPS, geranyl diphosphate synthase; IDI, isopentenyl diphosphate isomerase; IPP, isopentenyl diphosphate; PSY, phytoene synthase; TPS, terpenoid synthase.
