A composition for transportation of phytochelatin including a DNA molecule encoding an ABCC (multidrug resistance-associated protein (MRP)) subfamily of ATP-binding cassette (ABC) transporter protein in a plant is provided. The composition for transportation of phytochelatin can be useful in accumulating and sequestering phytochelatin alone or in combination with a harmful substance by transporting the phytochelatin and/or harmful substance into the vacuole of a cell, thereby reducing a content of the toxic substance which moves from the root to the shoot of a plant. Therefore, the DNA molecule can be applied to develop a crop in which the toxic substance present in edible parts, such as leaves, stems and fruits, of the plant is reduced in content. Furthermore, the DNA molecule can be applied to inedible plants to develop plants useful for phytoremediation or phytoextraction due to an increase in accumulated amount of and resistance against arsenic, an arsenic compound and cadmium, thereby making it possible to achieve phytoremediation or phytoextraction in an environmentally friendly and economically clean manner. |
