Tolerance and antioxidant response to heavy metals are differentially activated in and .

Heavy metal pollution reduces the community of soil microorganisms, including fungi from the genus , which are plant growth promotors and biological control agents. Because of potential effects on crop productivity, the toxic effects of heavy metals (HMs) in are of interest. However, there have been few studies on the biochemical and molecular response to oxidation caused by exposure to copper (Cu), chromium (Cr), and lead (Pb) and whether this antioxidant response is species-specific.
