Aims Intensive land management practices can compromise soil biodiversity,thus jeopardizing long-term soil *** mycorrhizal fungi(AMF)play a pivotal role in promoting soil productivity through obligate symbiotic associations with ***,it is not clear how properties of plant communities,especially species richness and composition influence the viability of AMF populations in *** Here we test whether monocultures of eight plant species from different plant functional groups,or a diverse mixture of plant species,maintain more viable AMF *** address this question,we extracted AMF spores from 12-year old plant monocultures and mixtures and paired single AMF spores with single plants in a factorial design crossing AMF spore origin with plant species *** Findings AMF spores from diverse plant mixtures were more successful at colonizing multiple plant species and plant individuals than AMF spores from plant ***,we found evidence that AMF spores originating from diverse mixtures more strongly increased biomass than AMF from monocultures in the legume Trifolium repens *** viability and ability to interact with many plant species were greater when AMF spores originated from 12-year old mixtures than *** results show for the first time that diverse plant communities can sustain AMF viability in soils and demonstrate the potential of diverse plant communities to maintain viable AMF propagules that are a key component to soil health and productivity.

植物-丛枝菌根真菌(AMF)可以调节竞争植物之间的土壤资源,以影响植物资源的捕获和适应性,使AMF成为植物共存的潜在媒介。本研究使用6种菌根状态不同的植物物种,通过生态位和适应性差异评估植物共存。在有或没有AMF的情况下,将15对竞争植物种植在一起。AMF对共存的影响是通过参数化成对的Lotka-Volterra植物竞争模型来确定的。通过比较在没有与AMF竞争的情况下生长的单个植物的枝条生物量与没有AMF的枝条生物量来确定6种植物物种对AMF的响应。研究结果表明,接种AMF减少了竞争者之间的适应度差异,但AMF介导的共存程度取决于竞争植物物种的身份。竞争植物物种之间更大的AMF响应差异减少了生态位重叠并增加了共存。这些结果说明,虽然AMF通常会减少适应性差异,但AMF的均衡效应并不总是足以克服由于生态位重叠导致的竞争不平衡,因此并不总是导致共存。相反,不同植物物种对AMF的内在生长反应可以预测生态位重叠减少,进而导致共存。这表明菌根依赖是一种旨在降低与竞争植物物种的生态位重叠程度,从而实现更多共存的植物策略。
