Structural analysis of rice Os4BGlu18 monolignol β-glucosidase. [PDF]
PLoS ONE, 2021 Monolignol glucosides are storage forms of monolignols, which are polymerized to lignin to strengthen plant cell walls. The conversion of monolignol glucosides to monolignols is catalyzed by monolignol β-glucosidases.

Plant cell wall lignification and monolignol metabolism [PDF]
Frontiers in Plant Science, 2013 Plants are built of various specialized cell types that differ in their cell wall composition and structure. The cell walls of certain tissues (xylem, sclerenchyma) are characterized by the presence of the heterogenous polymer lignin that plays an ...

Profiling of oligolignols reveals monolignol coupling conditions in lignifying poplar xylem [PDF]
Plant Physiology, 2004 Lignin is an aromatic heteropolymer, abundantly present in the walls of secondary thickened cells. Although much research has been devoted to the structure and composition of the polymer to obtain insight into lignin polymerization, the low-molecular ...

Reductive Cleavage Method for Quantitation of Monolignols and Low‐Abundance Monolignol Conjugates [PDF]
ChemSusChem, 2018 AbstractInvited for this month's cover is the group of Prof. John Ralph at the University of Wisconsin–Madison. The image shows the fragmentation of various lignins into monomeric components using the derivatization followed by reductive cleavage (DFRC) method, with the included mechanism providing the details for the derivatization of these lignins ...

Understanding Lignification: Challenges Beyond Monolignol Biosynthesis [PDF]
Plant Physiology, 2010 Lignin, a major component of vascular plant cell wall, provides mechanical support for plants to stand upright and enables xylems to withstand the negative pressure generated during water transport.

Biomimetic oxidative copolymerization of hydroxystilbenes and monolignols
Science Advances, 2023 Hydroxystilbenes are a class of polyphenolic compounds that behave as lignin monomers participating in radical coupling reactions during the lignification. Here, we report the synthesis and characterization of various artificial copolymers of monolignols and hydroxystilbenes, as well as low-molecular-mass compounds, to obtain the mechanistic insights ...

Enzyme-Enzyme Interactions in Monolignol Biosynthesis [PDF]
Frontiers in Plant Science, 2019 The enzymes that comprise the monolignol biosynthetic pathway have been studied intensively for more than half a century. A major interest has been the role of pathway in the biosynthesis of lignin and the role of lignin in the formation of wood. The pathway has been typically conceived as linear steps that convert phenylalanine into three major ...

Plant Cell Biology: The ABC of Monolignol Transport [PDF]
Current Biology, 2012 Lignins are complex aromatic heteropolymers that reinforce the cell walls of terrestrial plants. A new study identifies an ATP-binding cassette ABC transporter that pumps a monolignol lignin precursor across the plasma membrane.

5-Hydroxyconiferyl Aldehyde Modulates Enzymatic Methylation for Syringyl Monolignol Formation, a New View of Monolignol Biosynthesis in Angiosperms [PDF]
Journal of Biological Chemistry, 2000 S-Adenosyl-L-methionine-dependent caffeate O-methyltransferase (COMT, EC 2.1.1.6) has traditionally been thought to catalyze the methylation of caffeate and 5- hydroxyferulate for the biosynthesis of syringyl monolignol, a lignin constituent of angiosperm wood that enables efficient lignin degradation for cellulose production.
