Glomalin: A Key Indicator for Soil Carbon Stabilization
2021In the last decades, many studies were addressed focusing on soil protection that helps sequestration and stabilization of organic carbon in soil aggregates. Soil aggregates are an association of primary soil particles, bacteria, fungi, plant root and soil organic matter.

The role of glomalin in mitigation of multiple soil degradation problems
Critical Reviews in Environmental Science and Technology, 2020There is a direct link between the increasing human population and soil degradation that raises current and future food security concerns.

Glomalin – Truths, myths, and the future of this elusive soil glycoprotein
Soil Biology and Biochemistry, 2021Abstract The term “Glomalin” was originally used to describe a hypothetical gene product of arbuscular mycorrhizal fungi (AMF) that was assumed to be a nearly ubiquitous, thermostable and highly recalcitrant glycoprotein, deposited in soils in large amounts, and deemed to indicate soil health and quality.

Comparison of efficacy of three extractants to solubilize glomalin on hyphae and in soil
Chemosphere, 2006Glomalin, a glycoprotein produced by arbuscular mycorrhizal (AM) fungi, is a major component of the humus fraction of soil organic matter. Glomalin is extracted from soil and hyphae of AM fungi by using sodium citrate at 121 degrees C in multiple 1-h cycles, but extensive extraction does not solubilize all glomalin in all soils.

Arbuscular mycorrhizae, glomalin, and soil aggregation
Canadian Journal of Soil Science, 2004Arbuscular mycorrhizae are important factors of soil quality through their effects on host plant physiology, soil ecological interactions, and their contributions to maintaining soil structure. The symbiosis is faced with numerous challenges in agroecosystems; in order to inform sustainable management strategies it is hence a high priority to work ...

Behavior of Bradford-reactive substances is consistent with predictions for glomalin
Applied Soil Ecology, 2013There is considerable controversy concerning detection in soils of the protein, glomalin, which is produced by arbuscular mycorrhizal fungi. Glomalin was originally defined as a substance that cross reacts with a monoclonal antibody formed against a substance in the cell walls of an arbuscular mycorrhizal fungus.

Glomalin production and accumulation in soilless pot cultures
Canadian Journal of Soil Science, 2010This study was designed to determine how glomalin production relates to accumulation in three sequential greenhouse culturing periods using a soilless potting medium. The data indicated that this stable glycoprotein was washed out the pot bottom, and did not accumulate in the hyphal chamber.

A pressure cooker method to extract glomalin from soils
Soil Science Society of America Journal, 2001Glomalin, a glycoprotein produced by arbuscular mycorrhizal fungi, is an important constituent of soil organic matter. Glomalin is insoluble in water or salt solutions commonly used in soil extractions. Solubilization of glomalin does occur in the presence of citrate at the temperature achieved by an autoclave (121°C, 103 kPa).

The response of glomalin-related soil proteins to fire or tillage
Geoderma, 2018Abstract Glomalin-related soil proteins (GRSP) are glycoproteins abundantly produced by arbuscular mycorrhizal fungi in roots and soil. They can be a significant component of soil organic matter, which effectively acts to bind mineral particles together, so improving soil structure.

Deposition of Glomalin-Related Soil Protein and Sequestered Toxic Metals into Watersheds
Environmental Science & Technology, 2007We hypothesized that glomalin-related soil proteins (GRSP) are eroded in sufficient quantities to influence metal loading into watersheds. We tested correlations among GRSP, Glomeromycota fungi, and metals (cadmium, iron, lead, and manganese) in proteins extracted from embankment soils at seven locations along an urban/coastal watershed.
