How Do Plant Cell Walls Extend? [PDF]

Plant Physiology, 1993
This article briefly summarizes recent work that identifies the biophysical and biochemical processes that give rise to the extension of plant cell walls. I begin with the biophysical notion of stress relaxation of the wall and follow with recent studies of wall enzymes thought to catalyze wall extension and relaxation.

Moss cell walls: structure and biosynthesis

Frontiers in Plant Science, 2012
The genome sequence of the moss Physcomitrella patens has stimulated new research examining the cell wall polysaccharides of mosses and the glycosyltransferases that synthesize them as a means to understand fundamental processes of cell wall biosynthesis

A core of cell wall proteins functions in wall integrity responses in Arabidopsis thaliana

Plant Direct
Cell walls surround all plant cells, and their composition and structure are tightly regulated to maintain cellular and organismal homeostasis. In response to wall damage, the cell wall integrity (CWI) system is engaged to ameliorate effects on plant ...

A Transcriptomic Analysis of Xylan Mutants Does Not Support the Existence of a Secondary Cell Wall Integrity System in Arabidopsis

Frontiers in Plant Science, 2018
Yeast have long been known to possess a cell wall integrity (CWI) system, and recently an analogous system has been described for the primary walls of plants (PCWI) that leads to changes in plant growth and cell wall composition.

Preparation of Onion Epidermal Cell Walls for Imaging by Atomic Force Microscopy (AFM)

Bio-Protocol, 2017
The growing plant cell wall is comprised of long, thin cellulose microfibrils embedded in a hydrated matrix of polysaccharides and glycoproteins. These components are typically constructed in layers (lamellae) on the inner surface of the cell wall, i.e.,

Foliar calcium application reduces fluorine accumulation in tea plant by regulating cell wall structure and gene expression

Frontiers in Plant Science
Tea plant can enrich a large amount of fluorine (F) in the cell wall of its mature leaves, thus posing the risk of excessive intake of F for tea consumers.

Uncovering plant-pathogen crosstalk through apoplastic proteomic studies

Frontiers in Plant Science, 2014
Plant pathogens have evolved by developing different strategies to infect their host, which in turn have elaborated immune responses to counter the pathogen invasion.

Catalysts of plant cell wall loosening [PDF]

F1000Research, 2016
The growing cell wall in plants has conflicting requirements to be strong enough to withstand the high tensile forces generated by cell turgor pressure while selectively yielding to those forces to induce wall stress relaxation, leading to water uptake and polymer movements underlying cell wall expansion.

Integrated physiological and transcriptomic analyses reveal that cell wall biosynthesis and expansion play an important role in the regulation of plant height in alfalfa*

BMC Plant Biology
Background Alfalfa (Medicago sativa L.) is a high-quality, high-protein forage, and the improvement and breeding of key traits are important for enhancing the productivity of alfalfa.

Pb induces plant cell wall modifications - in particular - the increase of pectins able to bind metal ions level

E3S Web of Conferences, 2013
Low - methylesterified pectin fraction, able to bind metal ions, is the cell wall compound which participates in land and water plant cell response to toxic metals. Protonemata of Funaria hygrometrica (Hedw.), root tips of Populus tremula x P.tremuloides
