Monolignol ferulate conjugates are naturally incorporated into plant lignins [PDF]

Science Advances, 2016
Plants have convergently evolved to use monolignol ferulate conjugates to produce lignins containing chemically labile backbone esters.

Peroxidases bound to the growing lignin polymer produce natural like extracellular lignin in a cell culture of Norway spruce

Frontiers in Plant Science, 2016
Lignin, an important component of plant cell walls, is a polymer of monolignols derived from the phenylpropanoid pathway. Monolignols are oxidized in the cell wall by oxidative enzymes (peroxidases and/or laccases) to radicals, which then couple with the

Pathogen and drought stress affect cell wall and phytohormone signaling to shape host responses in a sorghum COMT bmr12 mutant

BMC Plant Biology, 2021
Background As effects of global climate change intensify, the interaction of biotic and abiotic stresses increasingly threatens current agricultural practices. The secondary cell wall is a vanguard of resistance to these stresses.

Peroxidase-based oxidative polymerization of monolignols

Comptes Rendus. Chimie, 2017
Oxidative polymerization of the monolignols (sinapyl alcohol [SA] and coniferyl alcohol [CA]) has been performed using enzyme-based biocatalysts. The oxidation of SA, CA, or an SA/CA mixture has been carried out using peroxidase enzyme–assisted H 2 O 2 /

Engineering Monolignol 4-O-Methyltransferases to Modulate Lignin Biosynthesis [PDF]

Journal of Biological Chemistry, 2010
Lignin is a complex polymer derived from the oxidative coupling of three classical monolignols. Lignin precursors are methylated exclusively at the meta-positions (i.e. 3/5-OH) of their phenyl rings by native O-methyltransferases, and are precluded from substitution of the para-hydroxyl (4-OH) position.

Enzymatic dehydrogenative polymerization of monolignol dimers

Journal of Wood Science, 2015
The structure and biosynthesis of lignin are not yet fully understood, especially the step following the initial dimerization of monolignol. Liquid chromatograph mass spectrometer (LC–MS) was used to analyze the consumption rates of monolignol dimers formed by β-O-4, β-5, and β-β couplings between coniferyl alcohols in efforts to understand the ...

Dual Mechanisms of Coniferyl Alcohol in Phenylpropanoid Pathway Regulation

Frontiers in Plant Science, 2022
Lignin is a complex phenolic polymer that imparts cell wall strength, facilitates water transport and functions as a physical barrier to pathogens in all vascular plants.

Lignin biosynthesis: old roads revisited and new roads explored [PDF]

Open Biology, 2019
Lignin is a major component of secondarily thickened plant cell walls and is considered to be the second most abundant biopolymer on the planet. At one point believed to be the product of a highly controlled polymerization procedure involving just three ...
