Spectromicroscopic visualizations of plant cell wall chemistry allowed simultaneous tracking of changes to lignin and polysaccharide contents which provides new possibilities for investigating the complementary roles of lignin-modifying and carbohydrate-active...

What is the function of lignin deposition in a cell wall

Lignin is the second most abundant organic substance after cellulose on this earth The word Lignin was derived from the Latin word for wood lignum by de Candolle 1819 It is a polyphenolic polymer that strengthens and waterproofs the cell wall...

Frontiers Plant cell wall lignification and monolignol

Cell walls lignocellulosics are isolated from crude dried plant material The wall material is then weighted into aliquots and subdivided for the various assays Wall material is treated with acetyl bromide and the solubilized lignin quantified by UV-spectroscopy...

A Mechanism for Localized Lignin Deposition in the

Lignin deposition is a major cell wall modification that plants employ in many different cell types and in response to various environmental stresses Added to the fundamental importance of lignin is a biotechnological incentive to manipulate lignin formation as it remains a major obstacle for the utilization of cellulosic biofuels...

Cell Wall Structure and Function

nbsp 0183 32 A cell wall is a rigid semi-permeable protective layer in some cell types This outer covering is positioned next to the cell membrane plasma membrane in most plant cells fungi bacteria algae and some archaea Animal cells however do not have a cell wall The...

Cell Biology Up Against the Wall

nbsp 0183 32 Lignin is a waterproofing and strengthening cell wall polymer that is essential to the functioning of certain plant cells particularly those involved in water transport Water and dissolved solutes enter plants from the soil through the roots and are transported upwards in the lignified xylem to all parts of the plant...

Molecular Expressions Cell Biology Plant Cell Structure

nbsp 0183 32 The secondary plant cell wall which is often deposited inside the primary cell wall as a cell matures sometimes has a composition nearly identical to that of the earlier-developed wall More commonly however additional substances especially lignin are found in the secondary wall...

Cell Wall Damage

The plant cell wall is a dynamic and complex structure whose functional integrity is constantly being monitored and maintained during development and interactions with the environment In response to cell wall damage CWD putatively compensatory responses such as lignin production are initiated In this context lignin deposition could reinforce the cell wall to maintain functional...

Lignification and Advances in Lignin Imaging in Plant Cell

Lignin is a polyphenolic polymer of the plant cell wall formed by the oxidative polymerization of three main monomers called monolignols that give rise to the lignin H- G- and S-units...

Lignins Biosynthesis and Biological Functions in Plants

Lignin is one of the main components of plant cell wall and it is a natural phenolic polymer with high molecular weight complex composition and structure Lignin biosynthesis extensively contributes to plant growth tissue/organ development lodging resistance and the responses to...

The Effect of Lignin on Biodegradability

Because lignin is the most recalcitrant component of the plant cell wall the higher the proportion of lignin the lower the bioavailability of the substrate The effect of lignin on the bioavailability of other cell wall components is thought to be largely a physical restriction with lignin molecules reducing the surface area available to enzymatic penetration and activity Haug 1993...
