摘要

丛枝菌根真菌（AM）与大多数陆地植物形成共生关系，对植物生长和营养至关重要。AM真菌包括众所周知的肾小球菌门（G-AMF）和最近在毛霉门中建立的内源性菌门细根内生真菌，通常被视为假定的AMF （E-AMF）。然而，这些真菌群体的全球丰富性，特别是E-AMF，知之甚少。为了提供全面的全球G-AMF和E-AMF物种，我们分析了来自所有大陆和生物群系的4,733个采样点的全长ITS标记的长读测序数据。我们的研究首次提供了全球G-AMF和假定的E-AMF丰富度的综合估计，远远超过迄今为止报道的数量和分类群。具体来说，我们检测到8517个G-AMF的otu，超过了以前AMF丰富度的估计5到15倍。此外，我们为假定的E-AMF确定了600个otu，为该群体提供了第一个全球估计。

Global richness of arbuscular mycorrhizal fungi

Arbuscular mycorrhizal (AM) fungi form mutualistic associations with most land plants and are of pivotal importance for plant growth and nutrition. AM fungi include both the well-known phylum Glomeromycota (G-AMF) and the recently established clade of Endogonomycete fine root endophytes within the phylum Mucoromycota, often viewed as putative AMF (E-AMF). Yet, the global richness of these fungal groups, in particular of E-AMF, is poorly understood. To provide comprehensive global species of G-AMF and E-AMF, we analysed long-read sequencing data of the full-length ITS marker from 4,733 sampling sites across all continents and biomes. Our study provides the first combined estimate of global G-AMF and putative E-AMF richness, far exceeding the numbers and taxa reported so far. Specifically, we detected 8,517 OTUs of G-AMF, surpassing previous AMF richness estimates by a factor of five to fifteen. In addition, we identified 600 OTUs for putative E-AMF, providing the first global estimate for this group.

期刊介绍： Fungal Ecology publishes investigations into all aspects of fungal ecology, including the following (not exclusive): population dynamics; adaptation; evolution; role in ecosystem functioning, nutrient cycling, decomposition, carbon allocation; ecophysiology; intra- and inter-specific mycelial interactions, fungus-plant (pathogens, mycorrhizas, lichens, endophytes), fungus-invertebrate and fungus-microbe interaction; genomics and (evolutionary) genetics; conservation and biodiversity; remote sensing; bioremediation and biodegradation; quantitative and computational aspects - modelling, indicators, complexity, informatics. The usual prerequisites for publication will be originality, clarity, and significance as relevant to a better understanding of the ecology of fungi.
