This paper develops a method to isolate holocellulose nanofibrils that preserves native cellulose-xylan architecture, leading to high-performance sustainable materials.

This paper introduces a framework using protein language models to discover novel enzymes with specific functions by clustering sequence embeddings and recursively exploring functional reservoirs.

This study identifies AtMAN2 and AtMAN5 as novel factors required for glucomannan synthesis in Arabidopsis, alongside GDP-mannose generating enzymes and CslAs.

This study shows AGP-Ca2+ binding is essential for pollen development and tube growth in Arabidopsis, as mutants lacking this function exhibit reduced seed set and pollen abortion.

This study uses solid-state NMR to resolve the structure of plant cellulose microfibrils, revealing two interior glucose environments and four surface environments, challenging previous assumptions about crystallinity.

The paper identifies a conserved β-1,2-xylosyl modification in primary cell walls of gymnosperms and Arabidopsis, showing it is introduced by GT61 glycosyltransferases.

This study shows that the carbohydrate-binding module (CBM1) of TrCel7A improves enzyme binding and navigation on complex plant cell wall substrates.

This study shows that hydrothermal pretreatment makes peat susceptible to enzymatic saccharification by disrupting cell structure and releasing monosaccharides, but acidification from abiotic reactions inactivates enzymes.

This study shows that galactosyl modification on glucomannans in Arabidopsis cell walls is fine-tuned by MAGTs, affecting cellulose interaction and cell wall architecture.

This study identifies a convergent evolution of MBGT genes in asterids and rosids, showing different evolutionary pathways for similar biochemical functions.

The paper identifies the genetic basis of xylan side chain variability in plants and shows how pathogens adapt to degrade these structures, revealing evolutionary adaptations in both biosynthesis and degradation.

This paper identifies GONST2 as a GDP-Mannose transporter required for sphingolipid glycosylation in Arabidopsis, showing its role in growth and disease resistance.
