Arabinogalactan-Proteins as Boron-Acting Enzymes, Cross-Linking the Rhamnogalacturonan-II Domains of Pectin

open access: yesPlants, 2023
Most pectic rhamnogalacturonan-II (RG-II) domains in plant cell walls are borate-bridged dimers. However, the sub-cellular locations, pH dependence, reversibility and biocatalyst involvement in borate bridging remain uncertain. Experiments discussed here

The Staphylococcal Cell Wall

open access: yesMicrobiology Spectrum, 2019
ABSTRACT Dating back to the 1960s, initial studies on the staphylococcal cell wall were driven by the need to clarify the mode of action of the first antibiotics and the resistance mechanisms developed by the bacteria. During the following decades, the elucidation of the biosynthetic path and primary composition of staphylococcal cell walls ...

Bacterial glycobiology: rhamnose-containing cell wall polysaccharides in Gram-positive bacteria. [PDF]

open access: yes, 2016
The composition of the Gram-positive cell wall is typically described as containing peptidoglycan, proteins and essential secondary cell wall structures called teichoic acids, which comprise approximately half of the cell wall mass.

Histochemical Staining of Silica Body in Rice Leaf Blades

open access: yesBio-Protocol, 2015
Silicon (Si) is a biologically important element for plants in the order Poales (Yamamoto et al., 2011; Kido et al., 2015). In rice, Si is mainly deposited in the motor cells and the cell walls of the leaf epidermis.

The Cell Walls of Platymonas [PDF]

open access: yesJournal of General Microbiology, 1958
SUMMARY: Electron micrographs of cell walls of the unicellular green flagellate Platymonas subcordiformis revealed no evidence of a fibrous construction. A preparation of walls was isolated, hydrolysed, and analysed by paper chromatography. The major components indicated were galactose and a uronic acid; glucose was not detected.

Immunogold Labeling Analysis of Cell Wall Polysaccharides with Special Reference to (1;3,1;4)-β-D-glucan in Rice Cell Walls

open access: yesBio-Protocol, 2016
Various types of cell wall compositions have evolved to fulfill a wide range of biological roles during the diversification of land plants. (1;3,1;4)-β-D-glucan (MLG) is a defining feature of the cell walls in the order Poales (Yokoyama and Nishitani ...

Cracking the “Sugar Code”: A Snapshot of N- and O-Glycosylation Pathways and Functions in Plants Cells

open access: yesFrontiers in Plant Science, 2021
Glycosylation is a fundamental co-translational and/or post-translational modification process where an attachment of sugars onto either proteins or lipids can alter their biological function, subcellular location and modulate the development and ...

Homogalacturonan Accumulation in Cell Walls of the Green Alga Zygnema sp. (Charophyta) Increases Desiccation Resistance

open access: yesFrontiers in Plant Science, 2019
Land plants inherited several traits from their green algal ancestors (Zygnematophyceae), including a polysaccharide-rich cell wall, which is a prerequisite for terrestrial survival.

Molecular architecture of the PBP2–MreC core bacterial cell wall synthesis complex

open access: yesNature Communications, 2017
Bacterial wall biosynthesis is a complex process that requires the coordination of multiple enzymes. Here, the authors structurally characterize the PBP2:MreC complex involved in peptidoglycan elongation and cross-linking, and demonstrate that its ...

Sentinels at the wall: cell wall receptors and sensors [PDF]

open access: yesNew Phytologist, 2007
SummaryThe emerging view of the plant cell wall is of a dynamic and responsive structure that exists as part of a continuum with the plasma membrane and cytoskeleton. This continuum must be responsive and adaptable to normal processes of growth as well as to stresses such as wounding, attack from pathogens and mechanical stimuli.
