Abstract:

The processes of the lignin subunits biosynthesis pathway especially on the composition of lignin, the reaction steps, the enzymes involved in the lignin subunits biosynthesis pathway, and the rewriting of lignin roadmap were reviewed in this paper. The current researches in China were also discussed. In order to meet the different needs for industry wood and forage, some suggestions were proposed that the lignin biosynthesis research in China should be focused on the improvement of wood quality and forage digestibility, and the changes on total lignin content or subunits composition through the express regulation on the key lignin biosynthesis enzymes.

Key words: Lignin, Subunit, Biosynthesis pathway, Rewriting
