“…There were no spores or signs of root colonization in plants of the control treatment, thus indicating the absence of contamination. Variations in the responses of mycorrhizal colonization by different AMF species in the same plant grown in soil with excess of heavy metals have already been evidenced in several studies (Schneider et al, 2017;Li et al, 2017;Spagnoletti, Carmona, Gómez, Chiocchio, & Lavado, 2017;Brito, Carvalho, Alho, & Goss, 2014). In the present study, it is also possible to observe that the same treatments of inoculation with AMF (C. etunicatum and Mix) which had positive effect on plant development were also responsible for the highest percentages of mycorrhizal colonization.…”

“…AMF spore density in soil was significantly higher in the rhizosphere of plants inoculated with C. etunicatum, followed by the treatment Mix, compared with the rhizosphere of plants inoculated with R. clarus (Figure 2A). The number of AMF spores in soil has been a parameter widely used by researchers to evaluate the effect of heavy metals on AMF (Rivera-Becerril et al, 2013;Schneider, Bundschuh, Rangel, & Guilherme, 2017;Garcia et al, 2017). A series of limitations, such as the reduction in spore germination, extraradical mycelium development and sporulation of some AMF species, has been reported in the presence of excess heavy metals in the soil (Pawlowska & Charvat, 2004;Yang et al, 2015b).…”

Mining and processing of manganese (Mn) minerals are activities that may result in the generation of large amounts of wastes and serious environmental impacts. Several strategies have been employed to remediate areas with high Mn concentrations, but many of them imply high investments and high risk of secondary pollution. This study aimed to evaluate the phytostabilization potential of Mimosa caesalpiniaefolia Benth. in Mn mining soil influenced by inoculation with arbuscular mycorrhizal fungi (AMF). The experimental design was completely randomized, with four treatments [not inoculated (control), inoculated with Rhizophagus clarus; inoculated with Claroideoglomus etunicatum and inoculated with Rhizophagus clarus + Claroideoglomus etunicatum (Mix)], and four replicates. Inoculation with Mix and C. etunicatum had higher efficiency in protecting plants against excess Mn, due to the greater retention of this element in the roots and lower translocation to the shoots. Inoculation with R. clarus did not influence plant development and reduction of Mn contents in the shoots. The association of the AMF Mix and C. etunicatum with the species Mimosa caesalpiniaefolia Benth. enhances Mn phytostabilization in mining soils with high concentration of this element. The use of multivariate analyses proved to be an important tool with respect to the behavior of biometric, chemical and microbiological variables in mining soil with high Mn concentration.

“…Orense) inoculated with R. irregularis in comparison with nonmycorrhizal plants (Merlos et al, 2016). Thus, it should be noted that the effects of mycorrhizal-assisted phytoremediation on the accumulation of HMs by host plants depend largely on the fungal isolates, the specific HMs, and other factors (Schneider, Bundschuh, Rangel, & Guilherme, 2017).…”

Uptake, translocation, detoxification, and sequestration of heavy metals (HMs) are key processes in plants to deal with excess amounts of HM. Under natural conditions, plant roots often establish ecto‐ and/or arbuscular‐mycorrhizae with their fungal partners, thereby altering HM accumulation in host plants. This review considers the progress in understanding the physiological and molecular mechanisms involved in HM accumulation in nonmycorrhizal versus mycorrhizal plants. In nonmycorrhizal plants, HM ions in the cells can be detoxified with the aid of several chelators. Furthermore, HMs can be sequestered in cell walls, vacuoles, and the Golgi apparatus of plants. The uptake and translocation of HMs are mediated by members of ZIPs, NRAMPs, and HMAs, and HM detoxification and sequestration are mainly modulated by members of ABCs and MTPs in nonmycorrhizal plants. Mycorrhizal‐induced changes in HM accumulation in plants are mainly due to HM sequestration by fungal partners and improvements in the nutritional and antioxidative status of host plants. Furthermore, mycorrhizal fungi can trigger the differential expression of genes involved in HM accumulation in both partners. Understanding the molecular mechanisms that underlie HM accumulation in mycorrhizal plants is crucial for the utilization of fungi and their host plants to remediate HM‐contaminated soils.

Arbuscular mycorrhizal fungi (AMF) are soil organisms that form mutualistic associations with most plants. The use of AMF is a strategy for the recovery of degraded soils, thus favoring the productivity of the crops. Native AMF can be selected from areas with particular soil and climatic conditions to be multiplied and used as inoculants, with better possibility of adaptation to degraded areas. The objective of this work was to characterize predominant native AMFs, from pastures of the northern zone of Peru. Soil samples from the areas of Carañayacu (A and B), Bosalao (A and B), Estero (A and B), Cercado (A and B), Chacrilla and Difuntillo in Cuñumbuque district in the San Martin region were collected. The soils were used as a substrate for the growth of two forage legumes including Centrosema macrocarpum and Leucaena leucocephala. A completely randomized design was used, with a factorial arrangement of 10 (zones) x 2 (legumes), with three repetitions. The results showed that the zones had greater influence in the percentage of mycorrhizal colonization in relation to the legumes, being the areas of Estero (72, 89%) and Difuntillo (70, 81%) those that had the highest percentage of colonization. The number of spores was influenced mainly by legumes, where Centrosema macrocarpum had the highest number with 710 spores / 10 g of soil from the Difuntillo area. Finally, 7 predominant native AMF morphotypes were characterized, being the morphotype of the Claroideoglomus genus the most predominant. AMF selected and multiplied under greenhouse conditions and reintroduced in areas of degraded pastures can increase their richness and, together with the installation of legumes, favor the recovery of degraded soils.
