Lignification: different mechanisms for a versatile polymer
Current Opinion in Plant Biology, 2015 Lignins are cell wall phenolic polymers resulting from monolignol radical coupling. They have characteristically high diversity in their structures which is a direct consequence of the versatile character of the lignification mechanisms discussed in this review.

Plant Journal, 2013 It has been suggested that, in Arabidopsis, auxin controls the timing of anther dehiscence, possibly by preventing premature endothecium lignification. We show here that auxin content in anthers peaks before the beginning of dehiscence and decreases when

Visualization of Suberization and Lignification in Sugarcane
2022Cell wall biopolymers are major factors responsible for the high recalcitrance of sugarcane biomass. The study of suberization and lignification mechanisms in sugarcane and of the networks that control biosynthesis of these polymers will contribute to the biotechnological improvement of this crop.

An approach to lignification in plants
Biochemical and Biophysical Research Communications, 1982Abstract A lignin-like substance was synthesized in vitro from coniferyl alcohol in the presence of peroxidase with coenzymes NADH and flavin. Eugenol was also polymerized in the same way.

Hydroxycinnamates in lignification
Phytochemistry Reviews, 2009Hydroxycinnamates incorporate into lignins by various mechanisms. The polysaccharide esters of ferulate, in particular, and the range of dehydrodiferulates and higher oligomers in grasses, participate in free-radical (cross-)coupling reactions during lignification to become integrally bound into the lignin polymer, resulting in extensive cross-linking ...

Abstract Phenylalanine and cinnamyl compounds have been infused into shoots of Eucalyptus botryoides and transformation products identified. The principal products identified were glucose esters ofcinnamic acids. Sinapic acid, besides giving its glucose ester, gave another substance which has been shown to be identical with a product given by air ...

The complete set of enzymes that catalyze the reactions from l-phenylalanine to substituted cinnamyl alcohols is now known. The latter compounds are the primary building stones of lignin. The individual reactions and the possible modes of regulation of this pathway are discussed.

Biochemistry and molecular biology of lignification
New Phytologist, 1995SUMMARYLignins, which result from the dehydrogenative polymerization of cinnamyl alcohols, are complex heteropolymers deposited in the walls of specific cells of higher plants. Lignins have probably been associated to land colonization by plants but several aspects concerning their biosynthesis, structure and function are still only partially ...

It has been well established that the typical woody plant is vascular, i.e., it possesses a specialized conducting system consisting of phloem and xylem, and it is perennial; in addition, it has a persistent stem that continues to live and increase in thickness for a number of years.
