Arbuscular mycorrhizal fungi alleviate the negative effects of iron oxide nanoparticles on bacterial community in rhizospheric soils. soil metagenome

Soil microorganisms are an indispensable component of agricultural ecosystems and are drivers of global biogeochemical cycles, including the cycling of carbon, nitrogen, sulfur and phosphorus. Therefore, microbial responses to ENPs are of great interest and provide valuable information that may aid in our understanding of the influence of ENPs on soil health. The community structure of soil bacterial assemblages has been previously studied. To display a high resolution of the soil bacterial community composition and to follow their shifts in response to a conccentration gradient of Fe3O4NPs, Miseq pyrosequencing technology was utilized in the present investigation.
