Fig. 5 in Specialized diterpenoid metabolism in monocot crops: Biosynthesis and chemical diversity

Fig. 5. Diterpenoid metabolism in switchgrass. Overview of the established modular diterpenoid-metabolic network in switchgrass (Panicum virgatum), involving the conversion of the central precursor geranylgeranyl diphosphate (GGDP) through the combined activity of class II diterpene synthases (green boxes) and class I diterpene synthases (blue boxes). Representative pathway products are highlighted. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
