Effects of Cellulose Structure of Sugarcane Stem on Mechanical Properties of Cell Wall

Journal of Natural Fibers
Cellulose is skeletal material of sclerenchymatous cell wall. The relationship between the structure of cellulose and the mechanical properties of the cell wall was studied in the research.

Measuring the distribution of cellulose microfibril angles in primary cell walls by small angle X-ray scattering

Plant Methods, 2014
BackgroundX-ray scattering is a well-established method for measuring cellulose microfibril angles in secondary cell walls. However, little data is available on the much thinner primary cell walls. Here, we show that microfibril orientation distributions

Production of Cellulose Microfibrils by Rhizobium [PDF]

Applied Microbiology, 1975
Electron microscope examination of Rhizobium spp. revealed microfibrils produced by flocculating strains but not by nonflocculating strains. The microfibrils from R. trifolii (NA30) were isolated and identified as cellulose by enzymatic, X-ray diffraction, and infrared spectral analyses. Both

The structure of the α-keratin microfibril

Bioscience Reports, 1983
Quantitative measurements of the intensity of the meridional reflections in the X-ray-diffraction pattern of α-keratin are shown to be consistent with a microfibril structure in which a surface lattice with an axially projected period around 200 Å is subject to a periodic interruption with an axially projected period of 470 Å. Taken in conjunction with

Microfibril angle and density patterns of fertilized and irrigated Norway spruce

Silva Fennica, 2004
Two Norway spruce nutrient optimisation trials, one in the north of Sweden and one in the south, were used to study the effects of intensive growth and fertilization on wood density and microfibril angle.

Quantification of microfibril angle in secondary cell walls at subcellular resolution by means of polarized light microscopy.

New Phytologist, 2013
The cell walls constitute the mechanical support of plants. Crystalline cellulose building the walls forms rigid microfibrils that set the stiffness of the cell and the direction in which it expands during growth.

Inelastic behaviour of cellulose microfibril networks

Soft Matter, 2018
Weak physical interactions between cellulose microfibrils play an important role in shaping the nonlinear rheological behaviour of their networks.

RADIAL VARIATION OF MICROFIBRIL ANGLE AND WOOD DENSITY AND THEIR RELATIONSHIPS IN 14-YEAR-OLD Eucalyptus urophylla S.T. BLAKE WOOD [PDF]

BioResources, 2011
The orientation of cellulose microfibrils in the cell wall along the stem axis has major effects on stiffness and longitudinal shrinkage and is of key importance in wood quality.

Investigation of Microfibril Angle of Flax Fibers Using X-Ray Diffraction and Scanning Electron Microscopy

Journal of Natural Fibers, 2020
Microfibril angle (MFA) of secondary cell wall has an important effect on the mechanical properties of flax fibers. It is therefore essential to study the relationships between MFA and mechanical properties.

A Structurally Specialized Uniform Wall Layer is Essential for Constructing Wall Ingrowth Papillae in Transfer Cells

Frontiers in Plant Science, 2017
Transfer cells are characterized by wall labyrinths with either a flange or reticulate architecture. A literature survey established that reticulate wall ingrowth papillae ubiquitously arise from a modified component of their wall labyrinth, termed the ...
