Comparison of efficacy of three extractants to solubilize glomalin on hyphae and in soil

Chemosphere, 2006
Glomalin, 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.

The response of glomalin-related soil proteins to fire or tillage

Geoderma, 2018
Abstract 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.

A pressure cooker method to extract glomalin from soils

Soil Science Society of America Journal, 2001
Glomalin, 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).

Deposition of Glomalin-Related Soil Protein and Sequestered Toxic Metals into Watersheds

Environmental Science & Technology, 2007
We 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.

Behavior of Bradford-reactive substances is consistent with predictions for glomalin

Applied Soil Ecology, 2013
There 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 content of forest soils in relation to fire frequency and landscape position

Mycorrhiza, 2003
Low-intensity, dormant season fires were frequent and widespread in oak-hickory ( Quercus-Carya) forests of eastern North America until widespread fire suppression began in the mid-1900s. To assess how reintroduction of fire into such ecosystems might affect the activity of arbuscular mycorrhizal (AM) fungi and, thereby, predict the long-term responses

Agricultural Perspectives of Mycorrhizal Glomalin as “Soil Fertility Determinants”

2019
Agriculture is a multifunctional unit that involves microorganisms, plants, and animals. They interact together by carrying out various metabolic functions either symbiotically or parasitically or mutualistically. Such interactions help maintain the ecological balance.

Seasonality of arbuscular mycorrhizal hyphae and glomalin in a western Montana grassland

Plant and Soil, 2003
In order to more fully understand the basic biology of arbuscular mycorrhizal fungi (AMF), and their role in natural ecosystems, it is necessary to document seasonal changes of various aspects of the life history of these fungi. Due to their unique position at the root-soil interface, AMF have been described as `keystone mutualists' in ecosystems ...

Is glomalin an appropriate indicator of forest soil reactive nitrogen status?

Journal of Plant Nutrition and Soil Science, 2017
AbstractIn this paper we address total glomalin‐related soil protein (T‐GRSP) as a possible indicator of differences in forest soils related to reactive nitrogen and forest composition. We focused especially on the relationship between T‐GRSP (g kg−1), soil organic carbon (SOC), and reactive nitrogen (Nr) availability among different categories of ...
