Figure 4 The synthesis of terpenoids in S. rosmarinus
Tissue-specific relative expression profiles (red–blue scale) of genes
implicated in terpenoid biosynthesis (heat map). Intermediates are shown
in black, and the enzymes involved at each step are shown in gray. The
genes involved in the pathways exhibit high level of expression, which
may contribute to the biosynthesis of large amounts of terpenes.
Monoterpene was biosynthesized by MVA pathway in cytoplasm, and
diterpene was biosynthesized by MEP pathway in plastid, framed with
green box. Grey boxes represent the genes on MVA pathway of S.
rosmarinus (left) and S. miltiorrhiza (right), and light green
boxes represent the genes on MEP pathway of S. rosmarinus (left)
and S. miltiorrhiza (right). All genes involved in the pathways
of MEP and MVA almost expanded in S. rosmarinus . MVA pathway
mevalonate pathway, MEP pathway mevalonate-independent (deoxyxylulose
phosphate) pathway, R root, S stem, L leaves.
