Phytochemistry, 1967
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 ...

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.

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.

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 ...

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.

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 ...

Naturwissenschaften, 1977
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.

Journal of Theoretical Biology, 1985
According to the author's proposed mechanism of lignification in plants, a further approach by physico-chemical theory, mostly the result of LCAO-MO manipulation, depicts the appropriate mechanism scheme and also describes the various linkages and formations in lignin structure.

Molecular Biology of Lignification in Grasses
2012As we transition into the twenty-first century, the need for renewable resources to address global energy and food demands has become a major concern. Around the world, scientists are interested in engineering dedicated biomass feedstocks particularly for improved cell wall composition by modifying the major wall components, cellulose and lignin.

Lignification: Flexibility, Biosynthesis and Regulation
Trends in Plant Science, 2016Lignin is a complex phenolic polymer that is deposited in the secondary cell wall of all vascular plants. The evolution of lignin is considered to be a critical event during vascular plant development, because lignin provides mechanical strength, rigidity, and hydrophobicity to secondary cell walls to allow plants to grow tall and transport water and ...
