Spectroscopic Analyses of the Biofuels-Critical Phytochemical Coniferyl Alcohol and Its Enzyme-Catalyzed Oxidation Products

open access: yesMolecules, 2009
Lignin composition (monolignol types of coniferyl, sinapyl or p-coumaryl alcohol) is causally related to biomass recalcitrance. We describe multiwavelength (220, 228, 240, 250, 260, 290, 295, 300, 310 or 320 nm) absorption spectroscopy of coniferyl ...

Taming the radical cation intermediate enabled one-step access to structurally diverse lignans

open access: yesNature Communications, 2022
Lignans, in spite of their structural diversity, are all biosynthetically derived from coniferyl alcohol. Here, the authors describe a divergent and stereoselective chemical synthesis of three types of lignans from biomass-derived monolignols, exploiting

Degradation of lignin β-aryl ether units in Arabidopsis thaliana expressing LigD, LigF and LigG from Sphingomonas paucimobilis SYK-6 [PDF]

open access: yes, 2017
Lignin is a major polymer in the secondary plant cell wall and composed of hydrophobic interlinked hydroxyphenylpropanoid units. The presence of lignin hampers conversion of plant biomass into biofuels; plants with modified lignin are therefore being ...

Genes encoding enzymes of the lignin biosynthesis pathway in Eucalyptus

open access: yesGenetics and Molecular Biology, 2005
Eucalyptus ESTs libraries were screened for genes involved in lignin biosynthesis. This search was performed under the perspective of recent revisions on the monolignols biosynthetic pathway.

Metabolomics Analysis Reveals the Effect of Two Alpine Foliar Diseases on the Non-Volatile and Volatile Metabolites of Tea

open access: yesFoods, 2023
Blister blight and small leaf spots are important alpine diseases that mainly attack tender tea leaves, affecting tea quality. However, there is limited information on the effect of these diseases on tea’s non-volatile and volatile metabolites ...

Sequestration and Transport of Lignin Monomeric Precursors

open access: yesMolecules, 2011
Lignin is the second most abundant terrestrial biopolymer after cellulose. It is essential for the viability of vascular plants. Lignin precursors, the monolignols, are synthesized within the cytosol of the cell.

Synthesis of highly deuterated coniferyl alcohol for silencing of NMR signals in the resulting dehydrogenative polymer

open access: yesJournal of Wood Science, 2022
To establish a facile methodology for the elucidation of the lignin chain-growth mechanism, the preparation of monolignol that does not show NMR signals in the dehydrogenative polymer (DHP) was attempted.

Modeling lignin polymerization, I: simulation model of dehydrogenation polymers [PDF]

open access: yes, 2010
Lignin is a heteropolymer that is thought to form in the cell wall by combinatorial radical coupling of monolignols. Here, we present a simulation model of in vitro lignin polymerization, based on the combinatorial coupling theory, which allows us to ...

Chemical genetics uncovers novel inhibitors of lignification, including p-iodobenzoic acid targeting CINNAMATE-4-HYDROXYLASE [PDF]

open access: yes, 2016
Plant secondary-thickened cell walls are characterized by the presence of lignin, a recalcitrant and hydrophobic polymer that provides mechanical strength and ensures long-distance water transport.

A versatile click-compatible monolignol probe to study lignin deposition in plant cell walls. [PDF]

open access: yesPLoS ONE, 2015
Lignin plays important structural and functional roles in plants by forming a hydrophobic matrix in secondary cell walls that enhances mechanical strength and resists microbial decay.
