Discovery of Lignin in Seaweed Reveals Convergent Evolution of Cell-Wall Architecture
Lignified cell walls are widely considered to be key innovations in the evolution of terrestrial plants from aquatic ancestors some 475 million years ago. Lignins, complex aromatic heteropolymers, stiffen and fortify secondary cell walls within xylem tissues, creating a dense matrix that binds cellulose microfibrils and crosslinks other wall components, thereby preventing the collapse of conduc...
متن کاملCellulose and the Hemicelluloses: Patterns for Cell Wall Architecture and the Assembly of Lignin
The results of our most recent studies point to significant coupling between the tetiia~ structures of all three major constituents of the cell wall in native woody tissue. It is clear that the hemicelluloses are intimately involved in the aggregation of cellulose, and the hemicelluloses, together wit h cellulose, provide the pattern for assembly of the lignin. Studies of the aggregation of bac...

15 صفحه اولInfluence of lignin on digestibility of forage cell wall material.
One-hundred-ninety-four grass samples, representing eight species, were used to determine the relationships of in vitro forage dry matter, cell wall, hemicellulose and cellulose digestibilities with lignin concentration. Linear regressions indicated that dry matter digestion was inhibited to a lesser degree (P less than .05) by lignin concentration than was cell wall digestion. Results for line...
