    摘要: The present invention relates to a method of producing transformants with enhanced resistance and decreased uptake of heavy metals, and a plant transformed with a P type ATPase ZntA gene that pumps out heavy metals from the cells. The transformants show better growth than wild type in environment contaminated with heavy metals and have lower heavy metal contents than wild type plants. Therefore, this method of transforming plants with ZntA or biologically active ZntA-like heavy metal pumping ATPases can be useful for developing plants for phytoremediation and also for a safe crop that has resistance to heavy metals and low heavy metal contents.
