Secondary cell wall patterning during xylem differentiation
Current Opinion in Plant Biology, 2012Xylem cell differentiation involves temporal and spatial regulation of secondary cell wall deposition. The cortical microtubules are known to regulate the spatial pattern of the secondary cell wall by orientating cellulose deposition. However, it is largely unknown how the microtubule arrangement is regulated during secondary wall formation.

Secondary cell walls (SCWs) are produced by specialized plant cell types, and are particularly important in those cells providing mechanical support or involved in water transport. As the main constituent of plant biomass, secondary cell walls are central to attempts to generate second-generation biofuels.

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.

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 ...

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.

PatB1 is an O-acetyltransferase that decorates secondary cell wall polysaccharides
Nature Chemical Biology, 2017O-Acetylation of the secondary cell wall polysaccharides (SCWP) of the Bacillus cereus group of pathogens, which includes Bacillus anthracis, is essential for the proper attachment of surface-layer (S-layer) proteins to their cell walls. Using a variety of pseudosubstrates and a chemically synthesized analog of SCWP, we report here the identification ...

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;

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

SUMMARYThe secondary cell wall (SCW) is essential for providing mechanical strength to plants, enabling upright growth and facilitating the long‐distance transport of water and nutrients through the vascular system. In this study, we generated an EMS‐induced mutant library in B73 maize and identified two “drought‐sensitive like” mutants, rlck1‐1 and ...
