Stomatal guard cells play a key role in the ability of plants to survive on dry land, because their movements regulate the exchange of gases and water vapor between the external environment and the interior of the plant. The walls of these cells are exceptionally strong and must undergo large and reversible deformation during stomatal opening and closing. The molecular basis of the unique strength and flexibility of guard cell walls is unknown. We show that degradation of cell wall arabinan… Expand
Stomatal Function Requires Pectin De-methyl-esterification of the Guard Cell Wall
TLDR
The results establish a link between gene expression in guard cells and their cell wall properties, with a corresponding effect on stomatal function and plant physiology. Expand
A conserved functional role of pectic polymers in stomatal guard cells from a range of plant species
TLDR
It appears that pectins and phenolic esters have a conserved functional role in guard cell walls even in grass species with type II walls, which characteristically are composed of low levels of pectin. Expand
Contrasting pectin polymers in guard cell walls of Arabidopsis and the hornwort Phaeoceros reflect physiological differences
TLDR
Arabinans and unesterified homogalacturonans are required for wall flexibility, which is consistent with active regulation of pore opening in Arabidopsis stomata, and the lack of arabinans and high levels of methyl-esterification in guard cell walls of Phaeoceros are congruent with the inability of hornwortStomata to open and close with environmental change.

Functional Analysis of Cellulose and Xyloglucan in the Walls of Stomatal Guard Cells of Arabidopsis1[OPEN]
TLDR
In cesa3je5 mutants defective in cellulose synthesis and xxt1 xxt2 mutants lacking the hemicellulose xyloglucan, stomatal apertures, changes in guard cell length, and cellulose reorganization were aberrant during fusicoccin-induced Stomatal opening or abscisic acid-inducedStomatal closure, indicating that sufficient cellulose and xylogucan are required for normal guard cell dynamics. Expand
Pectin methylesterase is required for guard cell function in response to heat
TLDR
The genetic data highlighted the significant role of PME34 in heat tolerance through the regulation of stomatal movement in Arabidopsis thaliana and suggested that this enzyme could require a specific cell wall modifying enzyme to function properly. Expand
Balancing Strength and Flexibility: How the Synthesis, Organization, and Modification of Guard Cell Walls Govern Stomatal Development and Dynamics
TLDR
The latest evidence for how wall polysaccharides are synthesized, deposited, reorganized, modified, and degraded in guard cells is discussed, and how these processes influence stomatal form and function is discussed. Expand
PECTATE LYASE LIKE12 patterns the guard cell wall to coordinate turgor pressure and wall mechanics for proper stomatal function in Arabidopsis.
TLDR
Stomatal guard cells are used to investigate the influences of wall mechanics and turgor pressure on cell deformation and demonstrate that the expression of the pectin-modifying gene PECTATE LYASE LIKE12 (PLL12) is required for normal stomatal dynamics in Arabidopsis thaliana. Expand
An α-expansin, VfEXPA1, is involved in regulation of stomatal movement in Vicia faba L.
TLDR
The results indicate the guard cell-expressed expansin VfEXPA1 plays an important role in regulation of stomatal opening. Expand
Cell Wall Modifying Proteins Mediate Plant Acclimatization to Biotic and Abiotic Stresses
TLDR
This review documents and discusses studies demonstrating the importance of timely cell wall modification during plant stress responses by focusing on a well-researched subset of wall modifying proteins. Expand
Adaptations of higher plant cell walls to water loss: drought vs desiccation.
TLDR
Common features and differences between these two water-deficit responses observed in plants are highlighted, emphasizing the role of the cell wall, while suggesting future research avenues that could benefit fundamental understanding in this area. Expand

Structural models of primary cell walls in flowering plants: consistency of molecular structure with the physical properties of the walls during growth.
TLDR
This review integrates information on the chemical structure of individual polymers with data obtained from new techniques used to probe the arrangement of the polymers within the walls of individual cells consistent with the physical properties of the wall and its components. Expand
Oligogalacturonic acid and chitosan reduce stomatal aperture by inducing the evolution of reactive oxygen species from guard cells of tomato and Commelina communis.
TLDR
The results suggest that guard cells infected by pathogens may close their stomata via a pathway involving H( 2)O(2) production, thus interfering with the continuous invasion of pathogens through the stomatal pores. Expand
Pectin: cell biology and prospects for functional analysis
TLDR
Current knowledge of biosynthetic enzymes, plant and microbial pectinases and the interactions of pECTin with other cell wall components and the impact of molecular genetic approaches are reviewed in terms of the functional analysis of pectic polysaccharides in plant growth and development. Expand
Characterization of the Cell-Wall Polysaccharides of Arabidopsis thaliana Leaves
TLDR
The cell-wall polysaccharides of Arabidopsis thaliana leaves have been isolated, purified, and characterized, and these cell walls are remarkable in that they are particularly rich in phosphate buffer-soluble poly Saccharides. Expand

TLDR
The modification of apple trees by a single PG gene has offered a new and unexpected perspective on the role of pectin and cell wall adhesion in leaf morphology and stomatal development. Expand
Guard cell volume and pressure measured concurrently by confocal microscopy and the cell pressure probe.

Guard cell turgor pressures in epidermal peels of broad bean (Vicia faba) were measured and controlled with a pressure probe and volume was estimated using direct linear integration to allow inference of guard cell osmotic content from stomatal aperture and facilitate accurate mechanistic modeling ofEpidermal water relations and stomatic functioning.

It seems that 25 years ago plant cell walls were different than they are now, but that is not true. Expand

The view of critical questions regarding pectin structure, biosynthesis, and function that need to be addressed in the coming decade are presented and new methods that may be useful to study localized pectins in the plant cell wall are described. Expand
Pectin esterification is spatially regulated both within cell walls and between developing tissues of root apices

In root apices of certain other species the JIM5 and JIM7 epitopes were found to be restricted to distinct tissues of the developing roots and other members of the Gramineae and also the Chenopodiaceae are shown to express similar restricted spatial patterns of distribution of these pectin epitopes inRoot apices.
