“…Physical remediation, chemical remediation and bioremediation are commonly used soil pollution control methods [6]. Among them, bioremediation technologies, including phytoremediation and microbial remediation, have received great attention due to their good ecological effects and economic development value [7]. Ectomycorrhizal fungi (ECMF) are widely distributed in soil and can coexist with most trees [8].…”

Ectomycorrhizal fungi can absorb heavy metals and allow host plants to develop resistance to heavy metal stress, but their heavy metal tolerance is not fully understood. In this study, the ability of Suillus bovinus (Sb) and Suillus placidus (Sp) to tolerate cadmium (Cd) was evaluated. Sb and Sp were treated with different Cd concentrations (0 (control), 0.2, 0.4 and 0.8 mg/L) under pure culture conditions, and the biomass, osmotic adjustment substance contents (soluble sugar and soluble protein), antioxidant enzyme activities (superoxide dismutase (SOD) and catalase (CAT)), pH and conductivity were examined. Sb biomass, soluble protein content and SOD activity first increased (0.2 mg/L and 0.4 mg/L Cd) and then decreased (0.8 mg/L Cd). Sp showed a similar change rule but a smaller range. Cd treatment increased the CAT activity of Sb and Sp but significantly reduced soluble sugars in Sb mycelium, whereas 0.2 mg/L Cd significantly increased soluble sugars in Sp mycelium. The pH and conductivity in the medium of Sb treated with different Cd concentrations showed more significant changes than those of Sp. The pH of Sp at 0 mg/L Cd and conductivity at 0.8 mg/L Cd were significantly lower than those of Sb. Correlation analysis suggested that Cd affected Sb more than Sp. In general, Cd treatment had less effect on the indexes of Sp, and Sp tolerated Cd better than Sb.

Anthropogenic activities have a critical influence on climate change that directly or indirectly impacts plant and microbial diversity on our planet. Due to climate change, there is an increase in the intensity and frequency of extreme environmental events such as temperature rise, drought, and precipitation. The increase in greenhouse gas emissions such as CO2, CH4, NOx, water vapor, increase in global temperature, and change in rainfall patterns have impacted soil–plant-microbe interactions, which poses a serious threat to food security. Microbes in the soil play an essential role in plants’ resilience to abiotic and biotic stressors. The soil microbial communities are sensitive and responsive to these stressors. Therefore, a systemic approach to climate adaptation will be needed which acknowledges the multidimensional nature of plant-microbe-environment interactions. In the last two scores of years, there has been an enhancement in the understanding of plant’s response to microbes at physiological, biochemical, and molecular levels due to the availability of techniques and tools. This review highlights some of the critical factors influencing plant-microbe interactions under stress. The association and response of microbe and plants as a result of several stresses such as temperature, salinity, metal toxicity, and greenhouse gases are also depicted. New tools to study the molecular complexity of these interactions, such as genomic and sequencing approaches, which provide researchers greater accuracy, reproducibility, and flexibility for exploring plant-microbe–environment interactions under a changing climate, are also discussed in the review, which will be helpful in the development of resistant crops/plants in present and future.
