“…The growth of hyphae in environments contaminated with metal(loid)s is reduced [94], but extensive growth of AMF-mycelium by affecting the surface properties of aggregates increases the level of heavy metal uptake in phytoremediation systems, increasing the storage of metal(loid)s in soil and roots and thus reducing the transfer of metal(loid)s to aerial parts [95,96]. As mentioned, AMF has various solutions to reduce the bioavailability and biological absorption of metal(loid)s in the soil, including GRSP and antioxidant activities [86,97]. Phosphate, sulfhydryl, and other compounds in mycelium can prevent the transfer of metal(loid)s from the roots to the soil by converting their ions into forms such as oxalic acid extract, which have poor biological activity [98].…”

“…In addition, AMF hyphae are easily intertwined on the soil particle surfaces and reduce their bioavailability and migration by adsorption and stabilizing Cd ions [96,163]. In addition, GRSP, which is the result of the degradation of AMF mycelium, can form a complex with Cd and significantly increase its uptake by soil particles [97,164]. On the other hand, AMF increases the formation of coarse-grained soil, which, with other factors mentioned above, reduced the Cd in porous water, thus reducing Cd leaching to the depth of soil and groundwater [49,105] (Figure 2).…”

The increasing expansion of mines, factories, and agricultural lands has caused many changes and pollution in soils and water of several parts of the world. In recent years, metal(loid)s are one of the most dangerous environmental pollutants, which directly and indirectly enters the food cycle of humans and animals, resulting in irreparable damage to their health and even causing their death. One of the most important missions of ecologists and environmental scientists is to find suitable solutions to reduce metal(loid)s pollution and prevent their spread and penetration in soil and groundwater. In recent years, phytoremediation was considered a cheap and effective solution to reducing metal(loid)s pollution in soil and water. Additionally, the effect of soil microorganisms on increasing phytoremediation was given special attention; therefore, this study attempted to investigate the role of arbuscular mycorrhizal fungus in the phytoremediation system and in reducing contamination by some metal(loid)s in order to put a straightforward path in front of other researchers.

“…The optimal role of arbuscular mycorrhizal fungi in 10 g/pot inoculation treatment was thought to be due to the high production of glomalin related soil protein (GRSP) so that it could absorb Al from the experimental soil. Wang et al (2019) reported that arbuscular mycorrhizal fungi could produce glomalin related soil protein (GRSP) through mycelium and spore walls. Glomalin related soil protein plays a role in absorbing aluminum (Al 3+ ) (Seguel et al 2013), and reducing the bioavailability of heavy metals (Siani et al 2017).…”

Abstract. Putra B, Warly L, Evitayani, Utama BP. 2021. The role of arbuscular mycorrhizal fungi in phytoremediation of heavy metals and their effect on the growth of Pennisetum purpureum cv. Mott on gold mine tailings in Muara Bungo, Jambi, Indonesia. Biodiversitas 23: 478-485. The increase of heavy metal pollution in the soil results from human activities such as gold mining, which impacts human and environmental health problems. Phytoremediation is an environmentally friendly, inexpensive, and efficient solution to overcome environmental damage caused by heavy metal contamination. Inoculation of AMF in dwarf Napier grass can reduce the level of metal contaminants in soil and subsequently its absorption in plant tissue. This study investigates the effect of arbuscular mycorrhizal fungi (AMF) on dwarf Napier grass (Pennisetum purpureum cv. Mott) plant growth and heavy metal remediation rates. The experiment was a completely randomized design with 4 levels of AMF inoculation (0, 5, 10, and 15 g/pot) with 5 repetitions. After eight weeks of potting experiments, shoot and root biomass, plant growth, heavy metal content in potting media were assessed. The results revealed that AMF inoculation of 10 g/pot exhibited a higher growth yield of dwarf Napier grass compared to other treatments (plant height (p<0.01), leaf length (P<0.01), leaf width (P<0.01), stem diameter (P<0.01) and plant fresh weight (P<0.01)), but had no significant effect on the number of leaves and number of shoots (P>0.05). AMF (10 g/pot) significantly affected root growth of dwarf Napier grass (root length (P<0.01), number of roots (P<0.05), and root fresh weight (P<0.01)). The results also showed that AMF increased the uptake of Al, Co, Cr, and Fe significantly in the growing media (Al (P<0.01), Co (P<0.05), Cr (P<0.01), Fe (P<0.05) but no significant effect on Pb (P>0.05). This study concluded that AMF effectively increased the growth of dwarf Napier grass and reduced heavy metal contaminants on gold mines tailings.

“…Arbuscular mycorrhizal fungi (AMF) colonized plant root hairs expand hyphal networks into surrounding soils [ 8 , 9 ]. AMF can change soil physical properties through forming macroaggregates that alter the surface traits [ 10 , 11 ] and increase the capability of surface adsorption of soils [ 12 ]. Plants can also be directly benefited by acquiring P, K, Ca, Mg, Cu, Zn, NH 4 + and NO 3 − via AMF [ 13 – 18 ].…”

Background Nutrients and heavy metals can be lost from soils via leaching, and arbuscular mycorrhizal fungi (AMF) can influence these events. Soil column experiments were carried out to examine whether leaching intensity and AMF can alter nutrient and Cd uptake in white clover plants and the extent of their losses through leaching. Results The presence of AMF significantly increased shoot and total biomass, as well as increased N, P, Cu and Zn uptake independent of water amount applied; while root P and Cu uptakes were promoted by AMF at any water amount treatments. Higher water amounts led to reductions in total N, K and Zn uptake for AMF-colonized plants in comparison to moderate water amount treatments. In the absence of AMF, white clover at low water amount treatment exhibited maximal root Cd uptake. At high water amount treatments, the presence of AMF significantly decreased leachate volumes and the amount of leached NH4+, K and Cd while AMF significantly increased the amounts of leached NO3−. Conclusions Overall we found that AMF-colonized white clover plants reduced NH4+, K and Cd loss from soils but increased the risk of NO3− loss under high intensity leaching conditions.
