Affinity chromatography of arabinogalactan-proteins☆
Carbohydrate Polymers, 1983Abstract Arabino-(1→3), (1→6)-β- d -galactan-proteins (AGPs) and related compounds from Lolium multiflorum (ryegrass) endosperm cell suspension culture, wheat endosperm, larchwood and Gladiolus stigma extract were shown to bind selectively at neutral pH to a column of Sepharose to which the anti-galactan myeloma protein J539 had been covalently ...

Extraction and Detection of Arabinogalactan Proteins
2010Arabinogalactan proteins are a diverse group of plant cell wall-associated proteoglycans. While structural and molecular genetic analyses have contributed to the emerging improved understanding of the wide-range of biological processes in which AGPs are implicated; the ability to detect, localise, and quantify them is fundamentally important.

Carbohydrate Research, 2011
Arabinogalactan-protein, previously isolated from instant coffee powder of Coffea arabica, has been subjected to partial mild acidic and enzymatic hydrolyses. Separation of obtained mixtures by size exclusion and HPLC chromatographies afforded series of oligosaccharides, structure of which were studied by NMR spectroscopy.

Arabinogalactan-proteins in spore-producing land plants
Carbohydrate Polymers, 2019Arabinogalactan-proteins (AGPs) are proteoglycans of the extracellular matrix of plants that were first isolated and described in the 1970s. Today, the consensus is that the following features are regarded as typical for these molecules: In contrast to broad knowledge on AGPs in seed plants, insight in occurrence and structure of AGPs in spore ...

Arabinogalactan proteins (AGPs) are high-molecular-weight transmembrane proteoglycans that are implicated in both the vegetative and reproductive stages of plant development. The bulk of an AGP molecule comprises of polysaccharide chains that are mostly anchored to the plasma membrane by glycosyl-phosphatidylinositol.

Arabinogalactan-proteins: structure, expression and function
Cellular and Molecular Life Sciences, 2001Arabinogalactan-proteins (AGPs) are a family of extensively glycosylated hydroxyproline-rich glycoproteins that are thought to have important roles in various aspects of plant growth and development. After a brief introduction to AGPs highlighting the problems associated with defining and classifying this diverse family of glycoproteins, AGP structure ...

A Brief History of Arabinogalactan-Proteins
2000In this paper key events in the development of our current understanding of the structure, functional roles and biosynthesis of arabinogalactan-proteins (AGPs) will be analyzed. In making this analysis, use has been made of citations in reviews (Smith and Montgomery 1959, Clarke et al 1979, Fincher et al 1983, Showalter 1993, Bacic et al 1996, Du et al

Structural Classes of Arabinogalactan-Proteins
2000Any consideration of the structural classes of arabinogalactan-proteins (AGPs) also raises the question, “What is an AGP?” The AGPs belong to the Hyp-rich glycoprotein (HRGP) family of molecules that also includes the extensins, Pro/Hyp-rich glycoproteins (P/HRGPs) and the solanaceous lectins (Showalter 1993, Kieliszewski and Lamport 1994, Du et al ...

Stress upregulates periplasmic arabinogalactan-proteins
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2005Stress upregulates AGPs typified by gum exudates, a well-known wound stress response. Salt-stress also dramatically upregulates AGP release; recently we showed that four species, adapted to growth as suspension cultures in high salt, gave much higher AGP yields (mg AGP/g cells fresh weight) and AGP release rates than control cells.

Arabinogalactan Proteins: Involvement in Plant Growth and Morphogenesis
Biochemistry (Moscow), 2005Arabinogalactan proteins (AGPs) are highly glycosylated hydroxyproline-containing variously located proteoglycans dynamically regulated in the course of plant ontogenesis. Special functions of AGPs are still unclear, but their involvement in vegetative growth and reproduction of plants is well established.
