Disrupting Two Arabidopsis thaliana Xylosyltransferase Genes Results in Plants Deficient in Xyloglucan, a Major Primary Cell Wall Component[W][OA]
It is concluded that XXT1 and XXT2 encode xylosyltransferases that are required for xyloglucan biosynthesis in vivo and this results in significant changes in the mechanical properties of these plants. Expand
Cell-wall recovery after irreversible deformation of wood
It is suggested that the molecular recovery mechanism in the cell matrix is a universal phenomenon dominating the tensile deformation of different wood tissue types. Expand

The micromechanical approaches reviewed here are not exhaustive, but they do provide a reasonably comprehensive overview of the methodology with which the general mechanisms underlying the functionality of plant micro- and nanostructure can be explored without destroying the entire cell wall.

CHITINASE-LIKE1/POM-POM1 and Its Homolog CTL2 Are Glucan-Interacting Proteins Important for Cellulose Biosynthesis in Arabidopsis[W][OA]
This article shows that the secreted CTL1/POM1 and its close homolog CTL2 interact with glucan-based polymers and influence cellulose crystallinity and cell expansion, and proposes that the apoplastic CTLs regulate cellulose assembly and interaction with hemicelluloses via binding to emerging cellulose microfibrils.

Cell wall features with regard to mechanical performance. A review COST Action E35 2004–2008: Wood machining – micromechanics and fracture
Abstract The mechanical performance of wood and wood products is highly dependent on the structural arrangement and properties of the polymers within the fibre cell wall. To improve utilisation andExpand
Moisture changes in the plant cell wall force cellulose crystallites to deform.
Findings imply a new perspective on the role of water adsorption perceiving a hydration-induced structural change of cellulose crystal structure as a major driving force for deformation in spruce wood tracheids. Expand
Stress generation in the tension wood of poplar is based on the lateral swelling power of the G-layer.
The results suggest that tensile stresses in poplar are generated in the living plant by a lateral swelling of the G-layer which forces the surrounding secondary cell wall to contract in the axial direction. Expand
The radial reinforcement of the wood structure and its implication on mechanical and fracture mechanical properties—A comparison between two tree species
The radial direction of wood is reinforced by an additional tissue called rays. These rays are one of the reasons for the anisotropy of wood in the transverse plane. In this paper the influence ofExpand
Plants control the properties and actuation of their organs through the orientation of cellulose fibrils in their cell walls.
Several examples, from trees to grasses, show that the cellulose architecture in the cell wall may be used to direct the swelling or shrinking of cell walls and thereby generate internal growth stress or movement of organs. Expand
The Role of Wheat Awns in the Seed Dispersal Unit
It is discovered that the awns of the dispersal unit of wild wheat are also able to propel the seeds on and into the ground, suggesting that the dead tissue is analogous to a motor. Expand
