“…Individual AMF isolates, or a mix of them, are increasingly used as bio‐inoculants for remediation of contaminated soils (e.g. Solís‐Ramos et al ., 2021), restoration of degraded lands (Maltz & Treseder, 2015; Asmelash et al ., 2016), and as biofertilizers for horticulture and crop production, though their production and application at large scales remain challenging (Berruti et al ., 2016; Igiehon & Babalola, 2017). Interestingly, we did not find differences between cultivable and wild plants, so the general patterns observed here may apply both to the restoration of natural communities and crop production.…”

The great majority of plants gain access to soil nutrients and enhance their performance under stressful conditions through symbiosis with arbuscular mycorrhizal fungi (AMF). The benefits that AMF confer vary among species and taxonomic groups. However, a comparative analysis of the different benefits among AMF has not yet been performed.We conducted a global meta-analysis of recent studies testing the benefits of individual AMF species and main taxonomic groups in terms of plant performance (growth and nutrition). Separately, we examined AMF benefits to plants facing biotic (pathogens, parasites, and herbivores) and abiotic (drought, salinity, and heavy metals) stress.AMF had stronger positive effects on phosphorus nutrition than on plant growth and nitrogen nutrition and the effects on the growth of plants facing biotic and abiotic stresses were similarly positive. While the AMF taxonomic groups showed positive effects on plant performance either with or without stress, Diversisporales were the most beneficial to plants without stress and Gigasporales to plants facing biotic stress.Our results provide a comprehensive analysis of the benefits of different AMF species and taxonomic groups on plant performance and useful insights for their management and use as bio-inoculants for agriculture and restoration.

“…Arbuscular mycorrhizal (AM) plants are known to exhibit an extra tolerance to many types of biotic and abiotic stresses [ 12 , 31 , 32 , 33 ]. Among the latter, HM contamination has been widely studied, and the results obtained have pointed to AM inoculation as an important, sustainable strategy that enhances the capacity of plants to remove and/or sequestrate contaminants from the soil [ 14 , 34 , 35 ]. In this study, the potential of AM inoculation to restore HM-contaminated soil in a mine-spill area of high ecological value is tested.…”

“…In particular, AMF species that belong to the genus Glomus have been used to increase the efficiency of phytoremediation practices employed in programs to rehabilitate certain areas [ 13 ]. In contrast, species from other genera, such as Acaulospora and Gigaspora, have been less studied for this purpose [ 14 ]. AM symbiosis is known to increase plant tolerance to various abiotic stresses, such as cold, drought, salinity, heavy metal, and emerging pollutants, by decreasing reactive oxygen species (ROS) accumulation; increasing the activities of antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD); by improving photosynthesis; and by promoting nutrient uptake [ 15 ].…”

Symbiotic associations with arbuscular mycorrhizal fungi (AMF) offer an effective indirect mechanism to reduce heavy metal (HM) stress; however, it is still not clear which AMF species are more efficient as bioremediating agents. We selected different species of AMF: Rhizoglomus custos (Custos); Rhizoglomus sp. (Aznalcollar); and Rhizophagus irregularis (Intraradices), in order to study their inoculation in wheat grown in two soils contaminated with two levels of HMs; we tested the phytoprotection potential of the different AMF symbioses, as well as the physiological responses of the plants to HM stress. Plants inoculated with indigenous Aznalcollar fungus exhibited higher levels of accumulation, mainly in the shoots of most of the HM analyzed in heavily contaminated soil. However, the plants inoculated with the non-indigenous Custos and Intraradices showed depletion of some of the HM. In the less-contaminated soil, the Custos and Intraradices fungi exhibited the greatest bioaccumulation capacity. Interestingly, soil enzymatic activity and the enzymatic antioxidant systems of the plant increased in all AMF treatments tested in the soils with both degrees of contamination. Our results highlight the different AMF strategies with similar effectiveness, whereby Aznalcollar improves phytoremediation, while both Custos and Intraradices enhance the bioprotection of wheat in HM-contaminated environments.

“…Arbuscular mycorrhiza (AM) fungi are probably the most widespread soil microorganisms, which can form symbiosis with most plants, and are the key node connecting the aboveground and underground ecosystems. Numerous studies have shown that AM fungi play an important role in the terrestrial ecosystem, with various functions such as improving plant growth and nutrient absorption (Bhantana et al., 2021), enhancing plant resistance to biotic and abiotic stresses (Amir et al., 2013), promoting nutrient geochemical cycle (Craig et al., 2018), improving soil structure (Lehmann et al., 2017) and repairing soil pollution (Solís‐Ramos et al., 2021).…”

The hydrological regime is considered to be the major factor that affects the distribution of arbuscular mycorrhiza (AM) fungi in wetlands. We aimed to investigate the responses of AM fungal community to different hydrological gradients. Illumina Miseq sequencing technology was used to study the AM fungal community structure in roots and rhizosphere soils of Phragmites australis in different moisture areas (dry area, alternating wet and dry area, and flooded area) in Mengjin Yellow River wetland. The rhizosphere soils and roots hosted different AM fungal communities. In roots, the AM fungal colonization and Chao1 richness in dry area were significantly higher than that in alternating wet and dry area and flooded area, but the community composition did not vary clearly under different water conditions. In rhizosphere soils, the Chao1 richness of AM fungi in flooded area was significantly higher than that in alternating wet and dry area and dry area, and the AM fungal community structure obviously differed across different areas. The redundancy analyses indicated that changes in the AM fungal community in soils were associated with altered soil properties, and the abundance of the dominant genus Glomus was mostly positively correlated with alkali‐hydrolyzable nitrogen in soils. This study helps us to understand the responses of AM fungal community to hydrological gradients in wetlands.
