Genes involved in santalol biosynthesis (terpenoid backbone biosynthesis pathway; MAP00900 from KEGG). Gene identifiers in boldface are the homologs of already cloned genes. The heat map shows iBAQ of proteome data in meristem, leaf, fruit, and stem. For RNA-seq, FPKM values are shown. GDS, Geranyl diphosphate synthase; HMBD, hydroxy methyl butenyl diphosphate.
