In pursuit of more sustainable and competitive biorefineries, the effective valorisation of
lignin is key. An alluring opportunity is the exploitation of lignin as a resource for chemicals …

Highlights•Hemicelluloses can interact with lignin through covalent cross-links in plant cell
walls.•Different reaction mechanisms can lead to cross-linking using diverse hemicellulose …

Background Lignin is a polyphenolic polymer that strengthens and waterproofs the cell wall
of specialized plant cell types. Lignification is part of the normal differentiation programme …

Lignin is a natural aromatic polymer of p-hydroxyphenylpropanoids with various biological
activities. Noticeably, plants have made use of lignin as biocides to defend themselves from …

Plant resistance to pathogens relies on a complex network of constitutive and inducible
defensive barriers. The plant cell wall is one of the barriers that pathogens need to …

Lignin is the generic term for a large group of aromatic polymers resulting from the oxidative
combinatorial coupling of 4-hydroxyphenylpropanoids (Boerjan et al., 2003; Ralph et al …

Abstract Background Secondary cell walls (SCWs) form the architecture of terrestrial plant
biomass. They reinforce tracheary elements and strengthen fibres to permit upright growth …

Phenylpropanoid biosynthesis in plants engenders a vast variety of aromatic metabolites
critically important for their growth, development, and environmental adaptation. Some of …

Lignin is a polymer of phenylpropanoid compounds formed through a complex biosynthesis
route, represented by a metabolic grid for which most of the genes involved have been …

Lignin is a major component of plant secondary cell walls. Here we describe caffeoyl
shikimate esterase (CSE) as an enzyme central to the lignin biosynthetic pathway …
