“…In addition, the low level of metal transporter may also help to reduce the heavy metal concentrations in ECM-fungi-colonized plants [ 24 ]. Some previous studies have demonstrated that ECM was able to fix Cd in the roots by cell wall binding and cytoplasmic chelation to reduce metal damage to aboveground parts [ 32 , 35 ]. We found that GO enrichment analysis of DEGs showed enrichment mainly in “transmembrane transport”, “ion transport”, “transport”, “organelle membrane”, “membrane”, “vacuolar”, “transmembrane transporter activity”, and “transporter activity” items ( Figure 9 ).…”

Pinus massoniana (Massion’s pine), a pioneer tree species, exhibits restoration potential in polluted mining areas. However, the physiological and molecular mechanisms of ectomycorrhizal (ECM) fungi in Massion’s pine adaptability to multiple-toxic-metal stress are still unclear. Hence, Massion’s pine seedlings inoculated with two strains of C. geophilum, which were screened and isolated from a polluted mine area, were cultivated in mine soil for 90 days to investigate the roles of EMF in mediating toxic metal tolerance in host plants. The results showed that compared with the non-inoculation control, C. geophilum (CG1 and CG2) significantly promoted the biomass, root morphology, element absorption, photosynthetic characteristics, antioxidant enzyme activities (CAT, POD, and SOD), and proline content of Massion’s pine seedlings in mine soil. C. geophilum increased the concentrations of Cr, Cd, Pb, and Mn in the roots of Massion’s pine seedlings, with CG1 significantly increasing the concentrations of Pb and Mn by 246% and 162% and CG2 significantly increasing the concentrations of Cr and Pb by 102% and 78%. In contrast, C. geophilum reduced the concentrations of Cr, Cd, Pb, and Mn in the shoots by 14%, 33%, 27%, and 14% on average, respectively. In addition, C. geophilum significantly reduced the transfer factor (TF) of Cr, Cd, Pb, and Mn by 32–58%, 17–26%, 68–75%, and 18–64%, respectively, and the bio-concentration factor (BF) of Cd by 39–71%. Comparative transcriptomic analysis demonstrated that the differently expressed genes (DEGs) were mainly encoding functions involved in “transmembrane transport”, “ion transport”, “oxidation reduction process”, “oxidative phosphorylation”, “carbon metabolism”, “glycolysis/gluconeogenesis”, “photosynthesis”, and “biosynthesis of amino acids.” These results indicate that C. geophilum is able to mitigate toxic metals stress by promoting nutrient uptake, photosynthesis, and plant growth, thereby modulating the antioxidant system to reduce oxidative stress and reducing the transport and enrichment of toxic metals from the root to the shoot of Massion’s pine seedlings.

Populus cathayana was used as a model species to investigate sexual differences in plant growth and physiological responses to lead (Pb) stress (0, 150 and 300 mg Pb 2+ kg-1 dry soil) with mycorrhizal (Myc) fungi colonization by Leucoagaricus sp. Results showed that high concentration of Pb stress (300 mg/ kg) caused disorder in photosynthesis, inhibited plant biomass, changed antioxidant enzyme activities and increased Malondialdehyde (MDA) content in both sexes, particularly in females. Male saplings showed greater biomass, gas exchange capacity, antioxidant enzyme activity and lower MDA content when exposed to Pb stress alone and to a combination of Pb and Myc fungi treatment. Furthermore, Leucoagaricus sp. inoculation alleviated Pb toxicity in both sexes by increasing biomass accumulation, promoting gas exchange capacity, enhancing antioxidant enzyme activities and decreasing relative electrolyte leakage under low concentration (150 mg/kg) and high concentration Pb stress. Inoculation with Leucoagaricus sp. promoted Pb uptake in both sexes, and induced the sequestration of more toxic Pb in the root systems in males. Therefore, P. cathayana males associated with Leucoagaricus sp. performed best under high concentration of Pb stress and more suitably restore Pb-polluted soils than inoculated females due to the higher Pb uptake capacity and greater growth traits.

“…The excess concentration of plant nutrient Zn can lead to increased production of ROS, which, if it breaks its balance with ROS destruction, results in oxidative stress ( Bartoli et al, 2013 ; Mohammadhasani et al, 2017 ). With evolution, plants acquire native defense mechanisms against oxidative stress, including antioxidant enzymes such as superoxide, catalase, glutathione peroxidase, ascorbate peroxidase, and guaiacol peroxidase ( Wu et al, 2014 ).…”

“…With evolution, plants acquire native defense mechanisms against oxidative stress, including antioxidant enzymes such as superoxide, catalase, glutathione peroxidase, ascorbate peroxidase, and guaiacol peroxidase ( Wu et al, 2014 ). Plants under HM stress can increase their antioxidant activities as a defense mechanism, and mycorrhizal symbiosis further enhances this activity ( Fernández-Fuego et al, 2017 ; Mohammadhasani et al, 2017 ). Catalase, peroxidase, ascorbate peroxidase, and superoxide dismutase are the antioxidants that play an essential role in alleviating the HM-induced oxidative stress in plants.…”

Soil heavy metal (HM) pollution, which arises from natural and anthropogenic sources, is a prime threat to the environment due to its accumulative property and non-biodegradability. Ectomycorrhizal (ECM) symbiosis is highly efficient in conferring enhanced metal tolerance to their host plants, enabling their regeneration on metal-contaminated lands for bioremediation programs. Numerous reports are available regarding ECM fungal potential to colonize metal-contaminated lands and various defense mechanisms of ECM fungi and plants against HM stress separately. To utilize ECM–plant symbiosis successfully for bioremediation of metal-contaminated lands, understanding the fundamental regulatory mechanisms through which ECM symbiosis develops an enhanced metal tolerance in their host plants has prime importance. As this field is highly understudied, the present review emphasizes how plant’s various defense systems and their nutrient dynamics with soil are affected by ECM fungal symbiosis under metal stress, ultimately leading to their host plants ameliorated tolerance and growth. Overall, we conclude that ECM symbiosis improves the plant growth and tolerance against metal stress by (i) preventing their roots direct exposure to toxic soil HMs, (ii) improving plant antioxidant activity and intracellular metal sequestration potential, and (iii) altering plant nutrient uptake from the soil in such a way to enhance their tolerance against metal stress. In some cases, ECM symbiosis promotes HM accumulation in metal stressed plants simultaneous to improved growth under the HM dilution effect.
