Gene expansions in monoterpenoid, diterpenoid, and sesquiterpenoid/triterpenoid biosynthesis pathways. (a) Monoterpenoid biosynthesis pathways in plants. Enzyme Commission number (EC) 4.2.3.25, (3S)-linalool synthase. (b) Diterpenoid biosynthesis in plants. EC 1.14.11.15, gibberellin 3-beta-dioxygenase; EC 1.14.11.13, gibberellin 2-oxidase; CYP82G1, cytochrome P450, family 82, subfamily G, polypeptide 1; EC 4.2.3.144, geranyllinalool synthase. (c) Sesquiterpenoid/triterpenoid biosynthesis. EC 4.2.3.22, 4.2.3.75, (-)-germacrene D synthase; EC 1.1.1.216, farnesol dehydrogenase. Phylogenetic analysis of (3S)-linalool synthase family (d), CYP82G1 (e), and (-)-germacrene D synthase family (f) in Solanum lycopersicum, Prunus mume, Morus notabilis, Myrica rubra, Citrullus lanatus, and Fragaria × ananassa. Values at the nodes indicate the percentage of bootstrap support from 1,000 replicates
