title: [Distribution and environmental function of glomalin-related soil protein: A review].
abstract: Glomalin-related soil protein (GRSP), a glycoprotein secreted by arbuscular mycorrhizal fungi (AMF), is abundant in soil. GRSP can be fractionated into total glomalin-related soil protein (TG), easily extracted glomalin-related soil protein (EEG), immunoreactive total glomalin (IRTG) and immunoreactive easily extracted glomalin (IREEG). The content of GRSP in soil differed with different soil use type, fertilization condition, AMF and host plant species, and environmental conditions. GRSP significantly positively correlates to the aggregate water stability. GRSP may reduce the release of CO2 in agro-ecosystem, benefit the soil carbon fixation, and reduce the bioavailability and plant toxicity of heavy metals in soil. The extraction and characterization of GRSP are of great importance to understanding the basic behaviors of GRSP in soil environments. Further studies are needed to clarify the molecular biology function of GRSP in agro-ecosystem based on the knowledge of proteins and related genes, and impacts of GRSP on the environmental behavior of organic pollutants in soil.
