Tissue-specific relative expression profiles (red–blue scale) of genes implicated in terpenoid biosynthesis (heat map). Intermediates are shown in black, and the enzymes (Supplementary Table 34) involved at each step are shown in gray. The genes involved in the MEP pathway exhibit a high level of fruit-development-specific expression, which may contribute to the biosynthesis of large amounts of monoterpenes. SesquiTPSs, or the responsible sesquiterpene biosynthesis of flowers, involve the gene expansion of 17 members (full amino acid length >200 aa). MonoTPSs involved in the production of monoterpenes in fruits also show signs of family expansion for 27 members (full amino acid length >200 aa) of L. cubeba. LcuTPSs form a gene cluster in chromosome 8 (Supplementary Fig. 5).
