“…The present results indicate that inoculum origin significantly affected AM fungal community structure, which demonstrates the importance of environmental filters on fungal community composition (Liu et al, ; Van Geel et al, ). However, temperature had no significant effect on AM fungal assemblages in root in the present study, which is not consistent with some previous studies (Antunes et al, ; Yang et al, ). Nevertheless, we found the evidence that the same fungal assemblages from low elevation generated different communities inside Imperata cylindrica roots under foreign temperature conditions ( F = 4.987, P = 0.034).…”

Summary Recent work demonstrates that habitat conditions exert striking effects on symbiont performance by mediating trade‐offs in plants, AM fungi and environmental interactions. However, how local temperature conditions influence the functional diversity of mycorrhizal symbioses and the genetics of coexisting AM fungi at the local scale remain unclear. In the present study, we conducted a reciprocal inoculation experiment to explore the performance of sympatric associations against allopatric associations under contrasting temperatures and the AM fungal community in colonized roots. No local adaptation of plant biomass was found under both temperature conditions investigated, but a consistent local versus foreign effect was found in AM fungal performance. The temperature and the origin of the inoculum relative to the plant origin were important in explaining symbiotic function. Correspondingly, the community structure and Nearest Relatedness Index of the AM fungal community of the root symbiont varied with inoculum source, and assemblages with more closely related taxa led to a decline in plant biomass and stronger disequilibrium among AM fungi in roots. Our findings suggest that functional divergence exists in naturally coexisting communities of AM fungi from contrasting climatic origins, and fungal relatedness is an important driver of plant growth.

“…This finding echoes studies that found local adaptation between native prairie plants and native prairie AM fungi (Middleton et al 2015; Koziol & Bever 2017; House & Bever 2019) as a general rule. More specifically, our results are consistent with Yang et al (2018) who found local adaptation of the plant‐AM fungi symbioses differed in contrasting abiotic environments. Further, the inoculated transplants of a drier origin demonstrated a marginally positive survival response in matching inoculum and moisture conditions.…”

The strength and direction of plant response to inoculation with arbuscular mycorrhizal fungi (AM fungi) is dependent on both abiotic and biotic contexts, often generating patterns of AM fungal mediation of plant adaptation. However, knowledge of plant‐community level effects of these interactions in grassland restoration is limited. We conducted a field inoculation experiment by inoculating five plant species native to a drier prairie and five plant species native to a moister prairie with mycorrhizal fungal communities from each prairie type. Species were paired by genus or family to account for phylogenetic effects. The inoculated plants were transplanted to study plots seeded with a restoration seed mix. Plots were manipulated to create either moister or drier conditions similar to environments of the plant species and mycorrhizal communities. In both transplanted and seeded plant species, we found that only drier prairie‐range species benefited from moisture‐regime matched AM fungal inoculum. Other seeded prairie plant species demonstrated a negative response to inoculation, likely due to the earlier successional stage of these species. Additionally, nonseeded plants benefited from inoculation in different ways: native nonseeded plants had highest cover with drier prairie inoculum in drier conditions, while nonnative plants had highest cover with moister prairie‐origin inoculum. These results suggest that use of local AM fungi may be particularly important in restorations at drier sites, even at relatively small differences in moisture availability. Further, specific knowledge of relative responsiveness of seeded plant species and nonseeded plant species to AM fungal inoculation will be useful in planning restorations.

“…To decrease such AMF uncertainties in restoration activities, researchers have tried to understand the factors influencing plant-AMF interactions and to find the optimal plant-AMF matches (Herrera-Peraza et al, 2011;Rua et al, 2016;Yang et al, 2018;Johnson and Gibson, 2020;Guisande-Collazo et al, 2022). According to the well-established plant-soil feedback theory, one plant species could specifically recruit the microbes beneath it (Bever, 1994;Bever et al, 1997;van der Putten et al, 2013).…”

Effects of arbuscular mycorrhizal fungi (AMF) on plants span the continuum from mutualism to parasitism due to the plant–AMF specificity, which obscures the utilization of AMF in the restoration of degraded lands. Caragana korshinskii, Hedysarum laeve, Caragana microphylla, and Poa annua are the most frequently used plants for revegetation in Kubuqi Desert, China, and the influence of AMF on their re-establishment remains to be explored further. Herein, using a greenhouse experiment, we tested the plant–AMF feedbacks between the four plant species and their conspecific or heterospecific AMF, retrieved from their rhizosphere in the Kubuqi Desert. AMF showed beneficial effects on plant growth for all these plant-AMF pairs. Generally, AMF increased the biomass of C. korshinskii, H. laeve, C. microphylla, and P. annua by 97.6, 50.6, 46.5, and 381.1%, respectively, relative to control. In addition, the AMF-plant specificity was detected. P. annua grew best, but C. microphylla grew worst with conspecific AMF communities. AMF community from P. annua showed the largest beneficial effect on all the plants (with biomass increased by 63.9–734.4%), while the AMF community from C. microphylla showed the least beneficial effect on all the plants (with biomass increased by 9.9–59.1%), except for P. annua (a 292.4% increase in biomass). The magnitude of AMF effects on plant growth was negatively correlated with the complexity of the corresponding AMF co-occurrence networks. Overall, this study suggests that AMF effects on plant growth vary due to plant-AMF specificity. We also observed the broad-spectrum benefits of the native AMF from P. annua, which indicates its potential utilization in the restoration of the desert vegetation.
