“…In addition to bacteria, the arbuscular mycorrhizal fungi (AMF) are also involved in phytoremediation of Cu, Mn and Zn. AMF are ubiquitous terrestrial symbionts involving functioning parts of plants living in mutualistic association with the fungi (Meier et al, 2012). Symbiotic mycorrhizal associations can increase the efficiency of phytoremediation due to improvements in the uptake and delivery of nutrients to the plant and in tolerance to metal toxicity (Bissonnette et al, 2010;Cornejo et al, 2013;Hernandez-Ortega et al, 2012).…”

“…Conversely, some authors demonstrated that the inoculation of plants by AMF such as Glomus species significantly enhanced PTE translocation to the aboveground parts of plants (Meier et al, 2012a). Levels of PTEs in soil may also affect the role of arbuscular mycorrhizal symbiosis (Audet and Charest, 2007), which can lead to an increase of plant metal uptake at low soil PTE concentrations as well as a reduction of PTE bioavailability via fungal metal-binding processes at high soil PTE levels.…”

This study aimed at evaluating the mid-term effect of ecto-and endomycorrhizal inoculation on the reduction of PTE mobility in soils and foliar accumulation by two poplar clones, Skado (Populus trichocarpa x P. maximowiczii) and I-214 (P. deltoides x P. nigra), dedicated to bioenergy purposes. The effects of inoculation were investigated in two large scale trials of 1 ha each. Poplars grown on highly contaminated soils accumulated excessive Cd and Zn in leaves compared with those planted on less contaminated soils, and the I-214 clone generally accumulated less PTEs than the Skado clone. Interestingly, the filtering capacity of mycorrhizal fungi was significant for Zn, Cu, Pb and Cr in Skado leaves only at the most contaminated areas after two growing seasons. These foliar concentrations were not correlated with Ca(NO3)2-extractable concentrations in soils, suggesting that mycorrhizal fungi limited PTE translocation from roots to leaves without impacting PTE mobility in soils. Therefore, the reduction of PTE accumulation in poplar leaves may be optimized by selecting appropriate combinations of cultivars and inocula at specific PTE levels and soil conditions.Because Cd and Zn may pose a risk after leaf abscission and wood harvest, further research is needed to efficiently reduce Cd and Zn concentrations in poplar tissues. Otherwise, the phytomanagement of metal contaminated sites with poplars should include options to safely manage both leaves and wood.

“…Copper production is Central to Chile's economy, but is responsible for a series of deleterious effects on ecosystems, producing irreversible losses of soil and plants (Meier et al, 2012b). For example, in the Mediterranean ecosystems near the Ventanas smelter (Puchuncaví Valley, Valparaíso Region), numerous negative effects have been generated by Cu-enriched particulate matter deposits and the acid rain generated by the smelter Cornejo et al, 2008;González et al, 2008).…”

The Bradford-reactive soil protein (BRSP) fraction includes glomalin, a glycoprotein produced by arbuscular mycorrhizal (AM) fungi able to bind some metals, such as copper (Cu), which could promote the bioremediation of Cu-polluted soils. This study aimed to analyze the Cu-binding capacity of BRSP in Oenothera picensis that was inoculated or not inoculated with AM fungi. O. picensis plants were established in a Cu contaminated sterilized soil and treated with the following: i) uninoculated (-M); ii) inoculated with native AM fungal propagules (+M); or iii) inoculated with a Claroideoglomus claroideum (CC) strain isolated from non-contaminated soil. In each case, five Cu levels were applied to the soil (basal level 497.3 mg Cu kg -1 ): 0 (T1); 75 (T2); 150 (T3); 225 (T4); and 300 mg Cu kg -1 (T5). A high BRSP accumulation in AM inoculated treatments, especially with CC, was observed. A higher Cu-bound-to-BRSP content was found with increasing Cu concentrations, representing up to 20-22% of the total Cu in the soil. Moreover, a higher root Cu concentration in +M was observed. These results suggest a high Cu binding capacity by BRSP, which is a relevant aspect to consider in the design of bioremediation programs together with the selection of endemic metallophytes and AM fungal strains, which are able to produce glomalin at high quantities.
