GM plant removes arsenic

A University of Georgia scientist has developed what is claimed to be the first transgenic system for removing arsenic from the soil using genetically modified plants. Researchers inserted two genes from the common bacterium Escherichia coli into Arabidopsis, a member of the mustard family. This allows it to tolerate arsenic, which is usually lethal to plants. The plant removes arsenic from the soil and transports it to its leaves.
