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.
球囊霉素相关土壤蛋白（GRSP）是一种由丛枝菌根真菌（AMF）分泌的糖蛋白，在土壤中含量丰富。GRSP可分为总球囊霉素相关土壤蛋白（TG）、易提取球囊霉素相关土壤蛋白（EEG）、免疫反应性总球囊霉素（IRTG）和免疫反应性易提取球囊霉素（IREEG）。土壤中GRSP的含量因土壤利用类型、施肥条件、AMF和宿主植物种类以及环境条件的不同而有所差异。GRSP与团聚体水稳定性显著正相关。GRSP可能会减少农业生态系统中二氧化碳的释放，有利于土壤碳固定，并降低土壤中重金属的生物有效性和植物毒性。GRSP的提取和表征对于理解GRSP在土壤环境中的基本行为具有重要意义。需要进一步研究，基于蛋白质和相关基因的知识阐明GRSP在农业生态系统中的分子生物学功能，以及GRSP对土壤中有机污染物环境行为的影响。
