Figure 1.
Rice labdane-related diterpenoid (LRD) metabolic network. Coloring indicates stereochemical or functional distinction. Dashed arrows indicate multiple enzymatic reactions leading to families of LRD derived from the shown diterpene olefins where known, while ‘???’ indicates presumed unknown derivatives (CPS, copalyl diphosphate synthase; KSL, kaurene synthase-like).
