Correlating macroscopic plant growth parameters to nanomechanical properties of cellulose microfibrils

Current Plant Biology
The plant cell wall, a vital component in providing structural integrity and facilitating growth, comprises cellulose microfibrils among its major constituents.

Effect of microfibril twisting on theoretical powder diffraction patterns of cellulose iβ

, 2013
Previous studies of calculated diffraction patterns for cellulose crystallites suggest that distortions that arise once models have been subjected to molecular dynamics (MD) simulation are the result of both microfibril twisting and changes in unit cell ...

X-Ray Diffraction Methods for Microfibril Angle Measurement in Maize and Sorghum Stalks

Agronomy
Stalk lodging (the structural failure of plant stems prior to harvest) remains a major constraint to global cereal crop production, reducing yields, impairing grain quality, and increasing harvest losses. Since cellulose microfibrils are the primary load-

Cellulose Microfibril Twist, Mechanics, and Implication for Cellulose Biosynthesis

, 2016
All-atom molecular dynamics simulations with explicit water solvent were used to investigate the microstructure and conformational dynamics of cellulose Iβ microfibrils as a function of microfibril length and cross-sectional size and shape.

Cellulose microfibril crystallinity is reduced by mutating C-terminal transmembrane region residues CESA1 A903V and CESA3 T942I of cellulose synthase [PDF]

, 2012
The mechanisms underlying the biosynthesis of cellulose in plants are complex and still poorly understood. A central question concerns the mechanism of microfibril structure and how this is linked to the catalytic polymerization action of cellulose ...

Cellulose Microfibril Structure: Inspirations from Plant Diversity

, 2018
Cellulose microfibrils are synthesized at the plasma membrane by cellulose synthase catalytic subunits that associate to form cellulose synthesis complexes. Variation in the organization of these complexes underlies the variation in cellulose microfibril

Real-time imaging reveals that lytic polysaccharide monooxygenase promotes cellulase activity by increasing cellulose accessibility

Biotechnology for Biofuels, 2018
Background The high cost of enzymes is one of the key technical barriers that must be overcome to realize the economical production of biofuels and biomaterials from biomass.

Transcriptome profiling of Pinus radiata juvenile wood with contrasting stiffness identifies putative candidate genes involved in microfibril orientation and cell wall mechanics

BMC Genomics, 2011
Background The mechanical properties of wood are largely determined by the orientation of cellulose microfibrils in secondary cell walls. Several genes and their allelic variants have previously been found to affect microfibril angle (MFA) and wood ...

Radial microfibril arrangements in wood cell walls

, 2022
MAIN CONCLUSION: TEM and AFM imaging reveal radial orientations and whorl-like arrangements of cellulose microfibrils near the S1/S2 interface. These are explained by wrinkling during lamellar cell growth.

Water as an Intrinsic Structural Element in Cellulose Fibril Aggregates

, 2022
[Image: see text] While strong water association with cellulose in plant cell walls and man-made materials is well-established, its molecular scale aspects are not fully understood.
