Abstract
Globally, $25-50 billion is spent each year cleaning up sites contaminated with heavy metals. Because traditional cleanup methods such as incineration, chemical treatment, and excavation and removal are costly and can damage the environment, metal-hyperaccumulating plants (plants that accumulate >0.1% heavy metals in leaves or other tissues) may be a more cost-effective, less-intrusive option for remediating such sites. Members of the Brassicaceae comprise 25% of metal-hyperaccumulating species worldwide discovered to date and are potential candidates for phytoremediation technologies. Here we describe the diversity of metal-hyperaccumulating species in the Brassicaceae and discuss the physiological mechanisms of metal uptake and tolerance, the genetic basis for the metal tolerance mechanisms, ecological consequences of metal hyperaccumulation, and the role of the Brassicaceae species in remediating contaminated sites worldwide.
