Purdue study finds antioxidant protects metal-eating plants Purdue University

An antioxidant, a type of compound that prevents certain types of damage to living cells, appears to allow some kinds of plants to thrive on metal-enriched soils that typically kill other plants, says a Purdue University scientist. This finding, published in the current issue of The Plant Cell, provides an important new insight for the development of plants that could be used to help clean polluted sites. The work also answers a fundamental question for researchers studying how certain types of plants tolerate levels of metals in their tissues that are toxic to most other plants.
