Microbial expression profiles in the rhizosphere of willows depend on soil contamination. soil metagenome

The goal of phytoremediation is to use plants to immobilize, extract or degrade organic and inorganic pollutants. In the case of organic contaminants, plants essentially act indirectly, through the stimulation of rhizosphere microorganisms. A detailed understanding of the effect plants have on the activities of rhizosphere microorganisms could help optimize phytoremediation systems and enhance their use. In this study, willows were planted in contaminated and non-contaminated soils in a greenhouse and the active microbial communities and the expression of functional genes in the rhizosphere and bulk soil were compared.
