Metabolomic Investigations Reveal Lignin Deconstruction by Human Gut Microbiota

This study shows human gut microbiota deconstruct lignin under anaerobic conditions, producing enterolignans and revealing rapid metabolism of lignin oligomers.

Ecologically inspired assembly of a Bacillales synthetic community for lignin degradation

This paper designs a synthetic microbial community for lignin degradation by integrating ecological and trait-based selection, showing enhanced lignin conversion through functional partitioning.

Ultrastructural analysis of engineered rice lines reveals ferulate cross-linking as a key factor mediating lignocellulose supramolecular assembly in grass cell walls

The paper analyzes engineered rice lines to show that ferulate cross-linking significantly affects lignocellulose structure and biomass properties more than lignin composition changes.

Engineering eudicot-like lignin in rice via targeted disruption of grass-specific lignin modification pathways

This study engineers rice to produce eudicot-like lignin by disrupting grass-specific lignin modification pathways, revealing the roles of p-coumarate and tricin in lignin structure and function.

Identifying and engineering the molecular origins of lignin color for predictive staining of plant tissues.

The paper identifies lignin chromogens responsible for plant tissue color and demonstrates genetic engineering to predictably stain lignified tissues.

Lignin degradation and valorization by Pseudomonas putida KT2440: a new role for glutathione peroxidase

This study identifies a new role for glutathione peroxidase in Pseudomonas putida KT2440, showing its involvement in lignin degradation and redox balance maintenance.

A Newly Identified Gene Controls Lignin Acetylation in Poplar

This study identifies a gene responsible for lignin acetylation in poplar and shows its overexpression increases acetate levels in lignin without affecting plant growth.

Stacked mutations disrupting syringyl and p-coumaroylated lignin biosynthesis in rice result in lignin dominated by guaiacyl units: insights into grass-specific lignin monomer biosynthesis and polymerization mechanisms

The paper shows that disrupting CAld5H and PMT genes in rice eliminates syringyl lignin, revealing a grass-specific pathway for p-coumarate conjugates and lineage-dependent lignin polymerization.

Co-Substrate Free Valorisation of Lignin Monomers by Assimilation of C1 and C2 By-Products

This study shows how by-products from lignin conversion can be used by Pseudomonas putida to eliminate the need for additional carbon sources, improving lignin valorisation efficiency.

Transcriptomic analysis of Picea abies tissue culture reveals the impact of culture conditions and the presence of glucuronoxylan on extracellular lignin production

This study uses transcriptomic analysis to investigate how culture conditions and xylan affect extracellular lignin production in Norway spruce tissue cultures.
