TL;DR: A cell wall proteoglycan with pectin and arabinoxylan covalently attached to an arabinogalactan protein is described, identifying a cross-linked matrix polysaccharide wall protein architecture with implications for wall structure, function, and synthesis.

TL;DR: The epitopes recognized by many of the mAbs in the toolkit, particularly those recognizing arabinose- and/or galactose-containing structures, are present on more than one glycan class, consistent with the known structural diversity and complexity of plant cell wall glycans.

TL;DR: It is shown that WRKY transcription factors are in part responsible for the parenchymatous nature of the pith cells in dicotyledonous plants and opens up the possibility of significantly increasing the mass of fermentable cell wall components in bioenergy crops.

TL;DR: The authors showed that XND1 overexpressions of Arabidopsis NAC domain transcription factor (XND1) resulted in extreme dwarfism associated with the absence of xylem vessels and little or no expression of tracheary element marker genes.

TL;DR: A new liquid ammonia pretreatment methodology called Extractive Ammonia (EA) was developed to simultaneously convert native crystalline cellulose Iβ (CI) to a highly digestible cellulose IIII (CIII) allomorph and selectively extract up to ∼45% of the lignin from lignocellulosic biomass with near-quantitative retention of all polysaccharides as mentioned in this paper.
