Network of metabolic pathways leading from Suc (orange, top left) to the volatile phenylpropanoids, phenylpropenes, and terpenoids formed in EMX-1 basil peltate glands (outlined with yellow backgrounds). Blue, Enzymes for which cDNAs have been identified in the basil peltate gland EST database, with the relative proportions in the database indicated in parentheses. Black, Known enzymes for which cDNAs have not yet been identified in the database. Red with brackets, Proposed enzymes in phenylpropene pathway for which genes are yet to be identified. Dashed lines, Hypothesized conversions. Green, SAM, an important substrate for phenylpropene biosynthesis.
