“…Accordingly, several studies have proposed that the rhizobiome of plants from polluted sites with heavy metals are rich in Proteobacteria, Actinomycetota, and Chloroflexota. Those phyla enhance the bioavailability of heavy metals by producing secondary metabolites, such as siderophores, which modify the medium by promoting the chelation and solubilization of heavy metals and influencing their translocation in the plant or increasing the production of biosurfactants (Liu et al 2022;de Lima et al 2022;Yadav et al 2023). Advancements in phytoremediation research have focused on isolating key microbial consortia with metabolic capacities to remove pollutants (Chen et al 2018b).…”

Due to the rapid expansion of industrial activity, soil pollution has intensified. Plants growing in these polluted areas have developed a rhizobiome uniquely and specially adapted to thrive in such environments. However, it remains uncertain whether pollution acts as a sufficiently selective force to shape the rhizobiome, and whether these adaptations endure over time, potentially aiding in long-term phytoremediation. Therefore, in the present study, we aimed to compare whether the microbiome associated with roots from plants germinated in polluted riverbanks will improve the phytoremediation of Cd and Pb under mesocosm experiments compared with plants germinating in a greenhouse. The experimental design was a factorial 2 x 2, i.e., the origin of the plant and the presence or absence of 100 mg/L of Cd and 1000 mg/L of Pb. Our results showed that plants germinated in polluted riverbanks have the capacity to accumulate twice the amount of Pb and Cd during mesocosm experiments. The metagenomic analysis showed that plants from the river exposed to heavy metals at the end of mesocosm experiments were rich in Rhizobium_sp_AC44_96 and Enterobacter sp. EA_1, Enterobacter soli, Pantoea rwandensis, Pantoea endophytica. In addition, those plants were uniquely associated with Rhizobium grahamii, which likely contributed to the differences in the levels of phytoremediation achieved. Furthermore, the functional analysis revealed an augmented functional potential related to hormones, metallothioneins, dismutases, and reductases; meanwhile, the plants germinated in the greenhouse showed an unspecific strategy to exceed heavy metal stress. In conclusion, pollution pressure drives microbial assemblages that improve the phytoremediation process.
