Outline of Final Research Achievements

Lignin, one of the main component of vascular plant cell walls, is highly polymerized and complex aromatic heteropolymer, derived from lignin monomers. As a result of many studies on lignin biosynthesis, the basic lignin monomer biosynthesis pathway have been clarified. On the other hand, lignin polymerization mechanism was not completely explained yet. This study focused on enzymatic activity, gene expression and localization of the enzymes that are expected to catalyze the reaction of lignin polymerization. The characteristics of the enzymes we found, clearly explained the lignin polymerization mechanism.
