Abstract

This invention relates to an isolated nucleic acid fragment encoding a heavy metal transporter. The invention also relates to the construction of a chimeric gene encoding all or a portion of the heavy metal transporter, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the heavy metal transporter in a transformed host cell.
