Metal hyperaccumulator plants are an unusual group of plants that are able to accumulate exceptionally high concentrations of metals such as zinc, nickel, copper and cadmium in their leaves. They are typically found growing in metal-rich soils, and are of interest because of their potential applications in remediation of metal pollution caused by mining and industry. However, the reasons why these plants do this are not fully understood. One possibility is that the toxicity of the accumulated metal provides an 'elemental' defence against herbivory and disease.
