“…On the other hand, some bacteria were identified with higher relative abundance in the industrial soil, such as Arthrobacter . These bacteria are normally found in the rhizosphere, being also present in HMs contaminated sites (Gallo et al, 2019). Ammonium-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) are sensitive to HMs and their enzyme activities can be used as bioindicators of HMs contamination (li et al, 2020).…”

Mining and industrial activity are contributing to the increase of heavy metal (HM) pollution in the environment, especially in soil. These metals leach into water, spread to plants and enter the food chain. Phytoremediation coupled to selected rhizosphere microbiota is an environmentally friendly technology designed to promote HM bioremediation in soils. In this study, sunflower ( Helianthus annuus L.) was used together with Rhizophagus irregularis, an arbuscular mycorrhizal fungi (AMF), and Cupriavidus sp. strain 1C2, a plant growth promoting rhizobacteria (PGPR), as a phytoremediation strategy to remove Zn and Cd from an industrial soil (599 mg Zn kg and 1.2 mg Cd kg ) and produce plant biomass - an agricultural soil was also used to obtain a H. annuus growth and metal accumulation control. The H. annuus biomass in the contaminated industrial soil was 17% lower, at harvest than that in an agricultural soil. Removals of ca. 0.04 and 0.91% of Zn and Cd respectively were obtained with the biomass produced in the industrial soil in a single crop. Bioaccumulation, remediation and translocation factors corroborated the higher Zn and Cd accumulation in the roots, compared to other plants parts. The survival of applied microbiota was indicated by a high root colonization rate of AMF and identification of strain 1C2 in the rhizosphere at the end of the phytoremediation assay. Changes in the bacterial community occurred in the industrial soil and were possibly associated to the phytoremediation effect on the rhizosphere: metals removal by the plant together with the synergic relationships established between AMF, PGPR and the autochthonous microbial community might have favoured specific soil bacterial genera, namely Nitrospira, Acidobacterium and Candidatus Koribacter. In this study, an optimized phytomanagement strategy applied to a real contaminated soil was successfully tested, and plant biomass with potential for upstream energetic valorisation purposes was produced.

“…Twenty-six investigations were performed on samples collected from areas with no association with either industries or mines, nor were they subjected to treatments with heavy metals or manure, and therefore focused on the natural presence of heavy metals. An example of this is represented by the study conducted by Gallo et al (2019) on soil samples obtained from sites for which there were no reports of contamination by heavy metals. In seven cases no data regarding sample locations were provided (Fig.…”

“…Among the integrons, class 1, which is frequently linked with ARGs and MRGs (Gillings et al, 2015), was the most commonly detected (n = 30), followed by class 2 (n = 14), 3 and 4 (n = 2 and n = 1, respectively). Four studies assessed the presence of plasmid mediated quinolone resistance (PMQR) (Gallo et al, 2019;Siddiqui et al, 2020;Tuo et al, 2018;Xu et al, 2017) and seven examined plasmid mediated beta lactam resistance (Figueiredo et al, 2019;Otinov et al, 2020;Pu et al, 2021a;Pu et al, 2021b;Wang et al, 2020;Wilson et al, 2019;Zhang et al, 2018c). In some cases (n = 9), an experiment was conducted to evaluate the mobility of resistance genes (conjugation transfer of ARGs) (Supplementary Table 2).…”

“…Even though the terrestrial area is a continually fluctuating and difficult place (Fierer, 2017), factors like limited nutritional and ion intensities that endorse competency, clay deposits that sustain the perseverance of bacteriophages and naked DNA, and the capacity of subsoil microbes to aggregate for genetic exchange suggest that HGT processes could be performing in this globalized context. Consistently, the transmission of antibiotic-resistance genes in the soil via MGEs (e.g., bacteriophage) has been highlighted as a public concern (Gallo et al, 2019;Zhang et al, 2022). Besides, soil is stratified geographically and varied physiologically and biologically on various dimensions, which offers a unique habitat for microbiota of diverse background.…”

The microbiota inhabiting soil plays a significant role in essential life-supporting element cycles. Here, we investigated the occurrence of horizontal gene transfer (HGT) and established the HGT network of carbon metabolic genes in 764 soil-borne microbiota genomes. Our study sheds light on the crucial role of HGT components in microbiological diversification that could have far-reaching implications in understanding how these microbial communities adapt to changing environments, ultimately impacting agricultural practices. In the overall HGT network of carbon metabolic genes in soil-borne microbiota, a total of 6,770 nodes and 3,812 edges are present. Among these nodes, phyla Proteobacteria, Actinobacteriota, Bacteroidota, and Firmicutes are predominant. Regarding specific classes, Actinobacteria, Gammaproteobacteria, Alphaproteobacteria, Bacteroidia, Actinomycetia, Betaproteobacteria, and Clostridia are dominant. The Kyoto Encyclopedia of Genes and Genomes (KEGG) functional assignments of glycosyltransferase (18.5%), glycolysis/gluconeogenesis (8.8%), carbohydrate-related transporter (7.9%), fatty acid biosynthesis (6.5%), benzoate degradation (3.1%) and butanoate metabolism (3.0%) are primarily identified. Glycosyltransferase involved in cell wall biosynthesis, glycosylation, and primary/secondary metabolism (with 363 HGT entries), ranks first overwhelmingly in the list of most frequently identified carbon metabolic HGT enzymes, followed by pimeloyl-ACP methyl ester carboxylesterase, alcohol dehydrogenase, and 3-oxoacyl-ACP reductase. Such HGT events mainly occur in the peripheral functions of the carbon metabolic pathway instead of the core section. The inter-microbe HGT genetic traits in soil-borne microbiota genetic sequences that we recognized, as well as their involvement in the metabolism and regulation processes of carbon organic, suggest a pervasive and substantial effect of HGT on the evolution of microbes.
