Secondary cell walls built with speed
Science, 2015Plant Science Plant cell walls provide the cellulose that is integral for wood, cotton fiber, and many biofuels. Cellulose is synthesized outside the cell membrane by cellulose synthase enzymes. Much of the secondary cell wall, responsible for the sturdiness of wood, is formed by xylem cells embedded in the core of the plant. Watanabe et al.

Microbiology, 2005
The cell wall of Gram-positive bacteria has been a subject of detailed chemical study over the past five decades. Outside the cytoplasmic membrane of these organisms the fundamental polymer is peptidoglycan (PG), which is responsible for the maintenance of cell shape and osmotic stability.

Cellulose-hemicellulose interaction in wood secondary cell-wall
Modelling and Simulation in Materials Science and Engineering, 2015The wood cell wall features a tough and relatively rigid fiber reinforced composite structure. It acts as a pressure vessel, offering protection against mechanical stress. Cellulose microfibrils, hemicellulose and amorphous lignin are the three major components of wood.

Biosynthesis and Regulation of Secondary Cell Wall
2019Secondary plant cell walls are produced by specialized plant cell types required for mechanical support and water transport. They are a microfibril-based composite constituted by celluloses, hemicelluloses, and lignins. Cellulose microfibrils are associated with hemicelluloses leading to the formation of a polysaccharide network that is impregnated by ...

Biophysics of cell wall architecture in secondary wall formation
1985Herein, secondary wall formation is discussed in the usual concept of identifying it with the thickening of cell walls, after extension growth under the influence of turgor pressure has ceased. For wood fibres,* there are many more data on the wide range of variations in the architecture of secondary walls, than is the case with other cells and plants;

Temperature signals drive grass secondary cell wall thickening
ABSTRACTIn grasses, stem elongation is driven by intercalary meristems at node-internode junctions, where cells divide, elongate, and in some cell types secondary wall maturation. Cellulose is the predominant polymer in plant cells and the most abundant biopolymer on Earth.Greg A. Gregory +9 more

Analysis of Secondary Cell Wall Formation in Arabidopsis
2001ABSTRACT A genetic approach has been taken to study secondary cell wall formation in Arabidopsis . Xylem elements that fail to form a secondary cell wall are unable to withstand the negative pressure generated during water transport and collapse inwards.

Mechanism for Diffusion through Secondary Cell Walls in Lignocellulosic Biomass
The Journal of Physical Chemistry B, 2019The future bioeconomy depends on the increased utilization of renewable lignocellulosic resources from trees and other bioenergy crops. However, considering that the diffusion of ions, chemicals, and enzymes into secondary cell walls is critical to effectively utilize lignocellulosic biomass, the unidentified mechanisms underpinning this diffusion have
