Inactivation of LACCASE8 and LACCASE5 genes in Brachypodium distachyon leads to severe decrease in lignin content and high increase in saccharification yield without impacting plant integrity

Biotechnology for Biofuels, 2019
Background Dedicated lignocellulosic feedstock from grass crops for biofuel production is extensively increasing. However, the access to fermentable cell wall sugars by carbohydrate degrading enzymes is impeded by lignins. These complex polymers are made

An ABC transporter is involved in the silicon-induced formation of casparian bands in the exodermis of rice [PDF]

, 2017
Silicon (Si) promotes the formation of Casparian bands (CB) in rice and reduces radial oxygen loss (ROL). Further transcriptomic approaches revealed several candidate genes involved in the Si-induced formation of CB such as ATP binding cassette (ABC ...

Biosynthesis of monolignols. Genomic and reverse genetic approaches [PDF]

Phytochemistry Reviews, 2003
The biosynthesis of monolignols is one of the most studied pathways of plant natural product biosynthesis. However, the pathway has recently undergone considerable revision, and it would appear that our understanding of the exact routes for synthesis of the building blocks of lignin and lignans is still not fully understood.

Analysis of a modern hybrid and an ancient sugarcane implicates a complex interplay of factors in affecting recalcitrance to cellulosic ethanol production [PDF]

, 2015
Abundant evidence exists to support a role for lignin as an important element in biomass recalcitrance. However, several independent studies have also shown that factors apart from lignin are also relevant and overall, the relative importance of ...

Lignin and Its Pathway-Associated Phytoalexins Modulate Plant Defense against Fungi

Journal of Fungi, 2022
Fungi infections cause approximately 60–70% yield loss through diseases such as rice blast, powdery mildew, Fusarium rot, downy mildew, etc. Plants naturally respond to these infections by eliciting an array of protective metabolites to confer physical ...

Visualization of plant cell wall lignification using fluorescence‐tagged monolignols [PDF]

The Plant Journal, 2013
SummaryLignin is an abundant phenylpropanoid polymer produced by the oxidative polymerization of p‐hydroxycinnamyl alcohols (monolignols). Lignification, i.e., deposition of lignin, is a defining feature of secondary cell wall formation in vascular plants, and provides an important mechanism for their disease resistance; however, many aspects of the ...

Interaction of monolignols and their related phenols with cellulose triacetate in various states

Journal of Wood Science
The present study comprises an investigation of the interactions of monolignols and their related phenols, such as catechol and vanillin (both are collectively referred to as “ML-phenols” herein), with cellulose triacetate (CTA) in solution, solid, and ...

Radical Coupling Reactions of Hydroxystilbene Glucosides and Coniferyl Alcohol: A Density Functional Theory Study

Frontiers in Plant Science, 2021
The monolignols, p-coumaryl, coniferyl, and sinapyl alcohol, arise from the general phenylpropanoid biosynthetic pathway. Increasingly, however, authentic lignin monomers derived from outside this process are being identified and found to be fully ...

Ozonolysis of Lignin: From Extensive Degradation to Selective Ring‐Opening Oxidation [PDF]

ChemSusChem
Despite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.
