Preserving Native Cellulose-Xylan Architecture Enables Structure-Property Control in Holocellulose Nanofibrils and High-Performance Sustainable Materials

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

Atypical endo-β-1,4-mannanases are necessary for normal glucomannan synthesis in Arabidopsis

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

Using solid-state NMR to understand the structure of plant cellulose

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.

GT61 β-1,2-xylosyltransferases define a conserved xylan modification in gymnosperm and Arabidopsis primary cell walls

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.

Glucomannan engineering highlights the role of galactosyl modification in fine-tuning cellulose-glucomannan interaction in Arabidopsis cell walls

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

Convergent Acquisition of Glucomannan β-galactosyltransferases in Asterids and Rosids

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