Lignin is a polymer of aromatic subunits usually derived from phenylalanine. It serves as a
matrix around the polysaccharide components of some plant cell walls, providing additional …

▪ Abstract After a long period of little change, the basic concepts of lignin biosynthesis have
been challenged by new results from genetic modification of lignin content and composition …

The lignin biosynthetic pathway has been studied for more than a century but has
undergone major revisions over the past decade. Significant progress has been made in …

Lignification is the process of forming the collective of phenylpropanoid macromolecules
termed lignin. There are two ways to define lignin: 1) from a chemical point of view (ie its …

A literature review in which studies of lignin structure and composition are examined from
both a chemical and a biological perspective. Plant enzymes with possible involvement in …

Lignins are phenolic polymers of the cell wall, and form the second most abundant group of
plant biopolymers after cellulose. The application of molecular genetics and powerful …

Lignins, which result from the dehydrogenative polymerization of cinnamyl alcohols, are
complex heteropolymers deposited in the walls of specific cells of higher plants. Lignins …

Lignin, a complex heteropolymer of cinnamyl alcohols, is, second to cellulose, the most
abundant biopolymer on Earth. Lignification has played a determining role in the adaptation …

Lignin deposition in plant cell walls is one of the mechanisms which allowed the
development of upright plants adapted to a terrestrial habitat. At the present time, lignins and …

Lignin occurs in cell walls of true vascular plants, ferns, and club mosses but not in those of
mosses, algae, and microorganisms (Kawa-mura and Higuchi, 1964). Lignin is generally …
