“…However, their abundance in seeds from SD could indicate potential adaptations to high levels of HM contamination, HM contamination is known to impose selective pressures on microbial communities, leading to the emergence of metal-tolerant or metal-utilizing strains. Studies have shown that Fusarium species like F. oxysporum and F. verticillioides possess mechanisms capable of tolerating cd contamination and play a role in reducing cd content in plants, These mechanisms include the production of metallothioneins and other metal-binding proteins, which can sequester and detoxify HM, thereby reducing their toxicity [25].…”

Heavy metal (HM) contaminants are the emerging driving force for reshaping the microflora of plants by eradicating the non-tolerance and non-resistant microbes via their lethal effects. Seeds serve as a primary source of microbial transmission from one plant generation to the next however, being exposed to metal contamination reshapes their microflora through generations. In this study, the endophytic diversity was compared within Zea mays seeds between three distinct regions in Yunnan province China i.e., HM-contaminated sites (AK) less-contaminated (SD), and a non-contaminated Site (DL). High throughput sequencing technique were used to analyze 492,177 high-quality reads for bacteria and 1,001,229 optimized sequences for fungi. Reads of interest were grouped into operational taxonomic units (OTUs), assigned to microbial genomes and analyzed for taxonomic information, alpha and beta diversity, taxonomic composition, and differential analyses. A higher diversity was recorded in AK samples than in SD and DL. Microbial community structure analysis showed higher diversity and significant fluctuation in specific taxa abundance in the metal-polluted samples exhibiting higher response of microbial flora to HM. In AK samples Gordonia and Burkholderia-Caballeronia-Paraburkholderi, were HM-resistant while Pseudomonas and Streptomyces showed moderate tolerance to HM. Fungal taxa such as Fusarium, Saccharomycopsis, and Lecanicillium also showed metal tolerance. The results revealed the role of HM in reshaping the microflora and their response in maize seeds. While investigating the microbiome from different environments of maize seeds using sequencing technology, the study will help in studying the microbiome shifts under HM conditions aiding better management strategies for reclaiming contaminated soil and crop management.

“…Moreover, plant and microorganism (fungi and bacteria) interactions at the root level (within the rhizosphere) can have synergistic beneficial effects in the remediation of heavy metal contamination in soil. Consequently, increasing interest has been given to creating and implementing combined bio- (the use of microorganisms) and phytoremediation strategies that are environmentally friendly, low in cost and unlikely to generate toxic by-products [ 41 , 42 , 43 , 44 , 45 , 46 , 47 ].…”

Mercury (Hg) pollution is a global threat to human and environmental health because of its toxicity, mobility and long-term persistence. Although costly engineering-based technologies can be used to treat heavily Hg-contaminated areas, they are not suitable for decontaminating agricultural or extensively-polluted soils. Emerging phyto- and bioremediation strategies for decontaminating Hg-polluted soils generally involve low investment, simple operation, and in situ application, and they are less destructive for the ecosystem. Current understanding of the uptake, translocation and sequestration of Hg in plants is reviewed to highlight new avenues for exploration in phytoremediation research, and different phytoremediation strategies (phytostabilization, phytoextraction and phytovolatilization) are discussed. Research aimed at identifying suitable plant species and associated-microorganisms for use in phytoremediation of Hg-contaminated soils is also surveyed. Investigation into the potential use of transgenic plants in Hg-phytoremediation is described. Recent research on exploiting the beneficial interactions between plants and microorganisms (bacteria and fungi) that are Hg-resistant and secrete plant growth promoting compounds is reviewed. We highlight areas where more research is required into the effective use of phytoremediation on Hg-contaminated sites, and conclude that the approaches it offers provide considerable potential for the future.
