“…Fungus have been reported to be more tolerant of metal stress than bacteria because of their strategies and different mechanisms. Li et al [40] and Hassan et al [41] reported that Chaetomium showed strong tolerance to multiple heavy metals. Fusarium and Mortierella were reported as the metal-resistant fungal genera [36,42].…”

The microbial effect of long-term heavy metal pollution on farmland remains unclear. Here, we investigated microbial (bacterial and fungal) communities in topsoil and rhizosphere samples with heavy metal (Cd, Cu, Pb, and Zn) pollution from four different types of tillage plots around an abandoned zinc smelter set up 85 years ago and analyzed the complex relationship between microorganisms, plants, and heavy metals (HMs) in soil to guide strategies for further soil remediation measures. The abundance and diversity index results showed that the bacterial and fungal diversities of the four plots were significantly different. Meanwhile, correlation analysis of the microbial communities and HMs showed that bacteria Pseudomonas and fungi Chaetothyriales and Fusarium had a good tolerance for HM pollution, but bacteria Vicinamibacteraceae, JG30_KF_CM45, RB41, Gaiella, MB-A2-108, 67-14, and Microvirga, and fungi Glomerellales, Hypocreales, Chaetomium, and Mortierella all showed indications of being sensitive to HM toxicity. Our structural equation model (SEM) attributed the inhibition of Zn and the promotion of Cd to bacterial diversity, attributed a weak inhibition of Cd to fungal diversity, and revealed the effects of the tillage type on these diversities.

“…Various transporter systems like cation diffusion facilitator, ATP-binding cassette, cation antiporters, natural resistance-associated macrophage, heavy metal ATPases, etc., are involved in ion homeostasis of essential metal ions and efflux of a toxic level of heavy metal (Viehweger, 2014). This transporter system assists in heavy metal accumulation, compartmentalization in inert form, and translocation into roots and shoots, negating the toxicity effect (Hassan et al, 2022). Metallochaperones play a pivotal role in the spatial relocation of metal ions in plant cells for further process according to relevance.…”

“…This augmented plant growth, biomass, and pigment production under metal toxicity (Mukherjee et al, 2022). Inoculation of a consortium of such endophytic fungi to Alocasia calidora imparted resistance and growth against landfill soil contaminated with a mixture of heavy metals through the production of compatible solute, antioxidant, and heavy metal bioaccumulation (root and shoot; Hassan et al, 2022). Recent works have demonstrated biochar's beneficial traits like high surface area for PGPM to attach, high carbon to increase soil organic matter, nutrient availability for the microbes, improved cation exchange efficiency, high water retention, etc., to improve 10.3389/fmicb.…”

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.
