Advances, Challenges, and Perspectives in Glomalin-Related Soil Protein Research

Area of Science:

• Soil Science
• Mycology
• Biogeochemistry

Background:

• Glomalin-related soil protein (GRSP), a glycoprotein from arbuscular mycorrhizal fungi (AMF), is vital for terrestrial ecosystems.
• Understanding GRSP's composition and functions is challenging due to its complex nature and analytical limitations.
• The growing body of GRSP research requires a comprehensive synthesis to guide future studies.

Purpose of the Study:

• To systematically analyze research trends and hotspots in Glomalin-related soil protein (GRSP) studies.
• To identify key research themes, influential articles, and emerging directions in GRSP research.
• To provide a scholarly resource for advancing GRSP research and its applications.

Main Methods:

• Bibliometric analysis of 840 articles from the Web of Science Core Collection.
• Evaluation of publication quantity, highly cited articles, and keyword frequencies.
• Analysis of historical direct citation networks.

Main Results:

• GRSP research concentrates on its nature, origin, quantification, influencing factors (agriculture, climate, land use), and ecological functions (soil stability, carbon sequestration, remediation).
• Bibliometric analysis revealed key research trends and areas of focus within the GRSP field.
• Identified dominant research topics including GRSP characterization, influencing factors, and ecological roles.

Conclusions:

• GRSP research is dynamic, with significant focus on its fundamental properties and ecological contributions.
• Emerging trends point towards understanding GRSP's role in sustainable agriculture and environmental remediation.
• This synthesis provides a roadmap for future research into GRSP's ecological functions and applications.
