“…These micronutrients are important for metabolic processes in plants (88), and their uptake can be positively influenced by AMF (89,90). Several studies showed strong negative effects of Zn soil contents on AMF abundance and diversity in polluted soils (20)(21)(22)(23). The Zn contents in our surveyed soils were far from those found in heavy metal-polluted soils; however, it seems that Zn can be a determinant in shaping the structure of AMF communities also in nonpolluted soils.…”

“…However, studies comparing the occurrence of specific AMF species and communities in different soil types are scarce and have focused mainly on cultivated soils and different land uses (10-13). Differences in soil types have been reported to be key factors determining AMF community composition (10), and this is particularly relevant in stressed environments such as serpentine soils (14-16), thermal soils (17), heavy metal soils, and saline soils (18)(19)(20)(21)(22)(23).Traditionally, studies on AMF abundance and distribution have been made by spore extraction from soil and identification based on the morphology and ontogeny of the spores. Thus, identification of spores has also been widely used to characterize AMF communities in soil (10,24,25).…”

We investigated communities of arbuscular mycorrhizal fungi (AMF) in the roots and the rhizosphere soil of Brachypodium retusum in six different natural soils under field conditions. We explored phylogenetic patterns of AMF composition using indicator species analyses to find AMF associated with a given habitat (root versus rhizosphere) or soil type. We tested whether the AMF characteristics of different habitats or contrasting soils were more closely related than expected by chance. Then we used principal-component analysis and multivariate analysis of variance to test for the relative contribution of each factor in explaining the variation in fungal community composition. Finally, we used redundancy analysis to identify the soil properties that significantly explained the differences in AMF communities across soil types. The results pointed out a tendency of AMF communities in roots to be closely related and different from those in the rhizosphere soil. The indicator species analyses revealed AMF associated with rhizosphere soil and the root habitat. Soil type also determined the distribution of AMF communities in soils, and this effect could not be attributed to a single soil characteristic, as at least three soil properties related to microbial activity, i.e., pH and levels of two micronutrients (Mn and Zn), played significant roles in triggering AMF populations. IMPORTANCECommunities of arbuscular mycorrhizal fungi (AMF) are main components of soil biota that can determine the productivity of ecosystems. These fungal assemblages vary across host plants and ecosystems, but the main ecological processes that shape the structures of these communities are still largely unknown. A field study in six different soil types from semiarid areas revealed that AMF communities are significantly influenced by habitat (soil versus roots) and soil type. In addition, three soil properties related to microbiological activity (i.e., pH and manganese and zinc levels) were the main factors triggering the distribution of AMF. These results contribute to a better understanding of the ecological factors that can shape AMF communities, an important soil microbial group that affects multiple ecosystem functions.A rbuscular mycorrhizal fungi (AMF) represent an important soil microbial group that affects multiple ecosystem functions and processes, including nutrient cycling, plant productivity and competition, and plant diversity. As a consequence, the number of ecological studies concerning AMF has increased considerably in recent years (1-9). Those studies considered AMF communities associated with different host plants in many different ecosystems. However, studies comparing the occurrence of specific AMF species and communities in different soil types are scarce and have focused mainly on cultivated soils and different land uses (10-13). Differences in soil types have been reported to be key factors determining AMF community composition (10), and this is particularly relevant in stressed environments such as serpentine soi...

The effect of arbuscular mycorrhizal fungus on the subcellular compartmentalization and chemical forms of lead (Pb) in Pb tolerance plants was assessed in a pot experiment in greenhouse conditions. We measured root colonization, plant growth, photosynthesis, subcellular compartmentalization and chemical forms of Pb in black locust (Robinia pseudoacacia L.) seedlings inoculated with Funneliformis mosseae isolate (BGC XJ01A) under a range of Pb treatments (0, 90, 900, and 3000 mg Pb kg-1 soil). The majority of Pb was retained in the roots of R. pseudoacacia under Pb stress, with a significantly higher retention in the inoculated seedlings. F. mosseae inoculation significantly increased the proportion of Pb in the cell wall and soluble fractions and decreased the proportion of Pb in the organelle fraction of roots, stems, and leaves, with the largest proportion of Pb segregated in the cell wall fraction. F. mosseae inoculation increased the proportion of inactive Pb (especially pectate- and protein-integrated Pb and Pb phosphate) and reduced the proportion of water-soluble Pb in the roots, stems, and leaves. The subcellular compartmentalization of Pb in different chemical forms was highly correlated with improved plant biomass, height, and photosynthesis in the inoculated seedlings. This study indicates that F. mosseae could improve Pb tolerance in R. pseudoacacia seedlings growing in Pb polluted soils.

“…Fungi may reduce transport of heavy metals through immobilization and compartmentalization via absorption into hyphal walls, reducing concentrations in above-ground plant tissues or accumulating in hyphal walls in a non-toxic form [206][207][208][209]. They have also been found to sequester heavy metals in plant roots, preventing translocation to shoots [210][211][212][213]. The ability to immobilize heavy metals in the fungal mycelium is thought to be the main protection mechanism for plants in contaminated soils [208,214].…”

Plants and arbuscular mycorrhizal fungi have co-evolved over a period of at least 450 million years. This fungal-plant association involves the transfer of carbon to the obligate biotropic fungus, in return for a wide range of beneficial functions. Although this is usually a mutualistic relationship, it can become parasitic to the plant under adverse conditions. Here, the research examining mechanisms by which mycorrhizal associations improve plant fitness is reviewed. Although there is strong evidence that a number of beneficial functions are performed by mycorrhizae, the mechanisms behind these are often not clear. There are numerous factors which influence these mechanisms and their outcomes, one or more of which can be affecting the association simultaneously. The knowledge we have on arbusular mycorrhizal associations with plants could be applied to various land management practices in order to improve soil degradation brought about by anthropogenic activities. These include erosion, drought, nutrient stress and salinization, and are often a result of poor land management. In order to use mycorrhizal fungi as a biomanagement tool, more research is required, particularly in mature field communities over long timescales. There is a need to invest in the development of sustainable agroecological management methods and to design future policy and legislation that encourages large organizations to incorporate more sustainable practices whilst protecting small-scale farmers.
