Fern cell walls and the evolution of arabinogalactan proteins in streptophytes

The Plant Journal, 2022
SUMMARY Significant changes have occurred in plant cell wall composition during evolution and diversification of tracheophytes. As the sister lineage to seed plants, knowledge on the cell wall of ferns is key to track evolutionary changes across tracheophytes and to understand seed plant‐specific evolutionary ...

Alleviation effect of arabinogalactan on decabromodiphenyl ether (BDE-209)-stimulated intestinal epithelial barrier damage via the Nrf2/HO-1/NQO1 signaling pathway in a Caco-2 cell monolayer model

Ecotoxicology and Environmental Safety
Decabromodiphenyl ether (BDE-209), a widely used polybrominated diphenyl ether, is a persistent environmental pollutant with intestinal toxicity. Arabinogalactan possesses antioxidant and anti-inflammatory properties, but its ability to counteract BDE ...

The Multiple Roles of Arabinogalactan Proteins in Plant Development [PDF]

Plant Physiology, 2000
Arabinogalactan proteins (AGPs) are: (a) structurally complex macromolecules composed of a polypeptide, large branched glycan chains, and lipid?; (b) markers of xylem development in Arabidopsis primary root?; (c) abundant extracellular matrix components in tobacco styles?; (d) active in tip ...

Chemical and structural characterization of hemicellulose from date fruits (Phoenix dactylifera L.)

Frontiers in Nutrition
In this study, we extracted hemicellulose from two date fruit cultivars (soft Barhi and hard Neghal) and investigated their structural, physicochemical, and thermal properties. Alkali solubilized more hemicellulose (45%–47.5%) than DMSO (6%–7%); however,

Structure and function of class III pistil-specific extensin-like protein in interspecific reproductive barriers

BMC Plant Biology, 2019
Background The transmitting tissue of the style is the pathway for pollen tube growth to the ovules and has components that function in recognizing and discriminating appropriate pollen genotypes. In Nicotiana tabacum, the class III pistil extensin-like (

Arabinogalactan Proteins In Plants

, 2013
AGPs (arabinogalactan-proteins) are the major constituent of arabic gum and have been used as emulsifiers and stabilizing agents. They are also one of the most abundant and heterogeneous class forming a large family of proteoglycans that sculpt the surface not only of plant but also of all eukaryotic cells.

GoSAMTs are required for pectin methyl-esterification and mucilage release in seed coat epidermal cells

Frontiers in Plant Science, 2023
IntroductionGoSAMTs play a role in the methylation of polysaccharides synthesized by the Golgi. Pectin homogalacturonan (HG) methyl-esterification is essential for the proper function of this polysaccharide in cell walls.

Changes in cell wall properties coincide with overexpression of extensin fusion proteins in suspension cultured tobacco cells.

PLoS ONE, 2014
Extensins are one subfamily of the cell wall hydroxyproline-rich glycoproteins, containing characteristic SerHyp4 glycosylation motifs and intermolecular cross-linking motifs such as the TyrXaaTyr sequence.

Emulsifying properties of Acacia senegal gum: Impact of high molar mass protein-rich AGPs

Food Chemistry: X, 2020
The impact of high molar mass protein-rich arabinogalactan-proteins (AGPs) on emulsifying properties of Acacia senegal gums were studied using reconstituted gums obtained with two distinct fractions: one containing these specific high molar mass AGPs and

Arabinogalactan proteins – Multifunctional glycoproteins of the plant cell wall

The Cell Surface, 2023
Arabinogalactan-proteins (AGPs) are cell wall glycoproteins that make up a relatively small component of the extracellular matrix of plants yet have significant influence on wall mechanics and signalling.
