Arbuscular mycorrhizal fungi (AMF) are important contributors to both plant and soil health. Twenty-five years ago, researchers discovered ‘glomalin’, a soil component potentially produced by AMF, which was unconventionally extracted from soil and bound by a monoclonal antibody raised against Rhizophagus irregularis spores. ‘Glomalin’ can resist boiling, strong acids and bases, and protease treatment. Researchers proposed that ‘glomalin’ is a 60 kDa heat shock protein produced by AMF, while others suggested that it is a mixture of soil organic materials that are not unique to AMF. Despite disagreements on the nature of ‘glomalin’, it has been consistently associated with a long list of plant and soil health benefits, including soil aggregation, soil carbon storage and enhancing growth under abiotic stress. The benefits attributed to ‘glomalin’ have caused much excitement in the plant and soil health community; however, the mechanism(s) for these benefits have yet to be established. This review provides insights into the current understanding of the identity of ‘glomalin’, ‘glomalin’ quantification, and the associated benefits of ‘glomalin’. We invite the community to think more critically about how glomalin-associated benefits are generated. We suggest a series of experiments to test hypotheses regarding the nature of ‘glomalin’ and associated health benefits.

对 25 年 glomalin 研究的批判性回顾:需要更好的机械理解和强大的量化技术
丛枝菌根真菌 (AMF) 是植物和土壤健康的重要贡献者。25 年前,研究人员发现了 AMF 可能产生的土壤成分“glomalin”,这种成分是从土壤中非常规提取的,并与针对不规则根霉的单克隆抗体结合孢子。'Glomalin' 可以抵抗煮沸、强酸和强碱以及蛋白酶处理。研究人员提出,'glomalin' 是一种由 AMF 产生的 60 kDa 热休克蛋白,而其他人则认为它是土壤有机物质的混合物,并非 AMF 独有。尽管对“glomalin”的性质存在分歧,但它始终与一长串植物和土壤健康益处相关,包括土壤聚集、土壤碳储存和在非生物胁迫下促进生长。'glomalin' 带来的好处在植物和土壤健康界引起了极大的兴奋。然而,这些好处的机制尚未建立。本综述提供了对当前对“glomalin”、“glomalin”量化以及“glomalin”相关益处的理解的见解。我们邀请社区更批判性地思考与 glomalin 相关的好处是如何产生的。我们建议进行一系列实验来检验关于“glomalin”的性质和相关健康益处的假设。
