“…In this study, Cd or excess Zn exerted negative effects on percent root colonization which decreased with increasing soil metal concentrations whereas MD increased, with Sel 85N exhibiting significantly better ability to associate with F. mosseae than P792. Elevated levels of metals in the soil hamper number of fungal spores together with their germination, germ tube and pre-symbiotic hyphal growth (Carrenho, Alves, & Santos, 2018). Our results of F. mosseae -pigeonpea relationship proved that AM fungus was functionally active in Cd or Zn polluted soils, suggesting that the fungal symbiont could thrive under the experimental metal concentrations.…”

“…Similar response was also observed for root dry matter (RDM), where inoculation with the AMF Mix followed by C. etunicatum led to significant increases of 26% and 16.5%, respectively, compared with non-inoculated plants ( Figure 1B). Enhancement in nutrient absorption from the soil solution and protection of plants against toxicity by heavy metals are benefits caused by the AMF which are related to the greater growth, generally in terms of dry matter, in mycorrhized plants (Carrenho, Alves, & Santos, 2018;Gunathilakae, Yapa, & Hettiarachchi, 2018). Li, Sun, Jiang, Chen, and Zhang (2018), studying the attenuation of toxicity by arsenic in Medicago sativa plants colonized by AMF, reported significant increase in shoot and root dry matter of mycorrhized plants at all levels of arsenic.…”

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.

“…Mining wastes originating from deep rock strata are generally unstable and prone to leaching at the Earth's surface, with increased solubility of trace metals (Sheoran et al, 2010;Bruneel et al, 2019). Surface mining produces typical by-products of extraction and processing that are devoid of vegetation cover (Schueler et al, 2011) and which are frequently impoverished in terms of their microbial symbionts and nutrients, making their rehabilitation more difficult (O'Dell et al, 2007;Carrenho et al, 2018;Lacalle et al, 2018;Chileshe et al, 2020).…”

“…As root symbioses have revealed an increased capacity for some plant species to perform strongly on dry and nutrient-poor soils (Anderson et al, 2008;Ndiaye et al, 2011;Carrenho et al, 2018;Kumar et al, 2018;Samba-Mbaye et al, 2020), symbiotic N 2 -fixing rhizobia and arbuscular mycorrhizal fungi (AMF) are especially important in nitrogen and phosphorus acquisition by plants (Duponnois et al, 1998), which have been previously used for the rehabilitation of mining sites (Bruneel et al, 2019;Festin et al, 2019) and even for promoting plant tolerance on contaminated soils (Kuffner et al, 2010;Lenoir et al, 2017). Yet, the success of rehabilitation activities strongly depends upon the effectiveness of fungi and other microbial populations in the substrate, together with its physicochemical characteristics (Quoreshi, 2008;Nadeau et al, 2018).…”

Establishment of plant communities at mine sites with significant disturbance depends upon factors such as the presence of efficient mycorrhizal fungi and rhizobia. Field and greenhouse experiments were conducted to assess growth performance of umbrella thorn as a potential tree species for reforestation of mine sites in arid areas. In the first experiment, seedlings were transplanted onto waste rock stockpile (WR) and tailings (TLG) with high arsenic (As) content on sites at the Essakane gold mine. Trees were assessed for growth and survival 3 years after planting. In experiment 2, soil was sampled on four sites across a disturbance gradient from mining waste (WR and TLG) and artisanal gold mining to undisturbed natural soil (NS). Each soil was planted with two separate leguminous trap crops (cowpea and umbrella thorn) in pots to check for microsymbionts. At 3 years, trees grew better on TLG soils with greater arsenic contamination than WRs in the field. Although tree establishment was moderate, with <50% survival, overall results suggest the ability of umbrella thorn to tolerate As contamination levels up to 1,300 ppm and, therefore, its potential for reforestation. Soil pH has shown strong effects on soil nutrient content. In particular, ammonium was the dominant form of mineral nitrogen (N) in the more neutral pH NS soils, while nitrate was present in the more alkaline WRs. Denitrification likely resulted in high N loss where nitrate dominates, reflecting the poor performance of N-deficient trees on WRs compared to TLG soils. Growth trends of umbrella thorn in potted-soils were consistent with those reported on TLG and WR soils in plantations.
