Abstract

The present invention relates to a composition for phytochelatin transport, comprising DNA molecules encoding ABCC (MRP, multidrug resistance-associated protein)-like ABC (ATP-binding cassette) transporter proteins in plants. The composition for phytochelatin transport according to the present invention can accumulate and sequester phytochelatin alone or in combination with a toxic substance by transporting same into the vacuole of a cell, and thus reduce the content of the toxic substance which moves from the root of a plant to the shoot thereof. Therefore, the DNA molecules of the present invention can be applied to the development of crops in which the content of toxic substances existing in edible plant parts such as leaves, stems, and fruits are reduced. Furthermore, the DNA molecules of the present invention are applied to inedible plants to develop plants which are useful in phytoremediation, or phytoextraction, by increasing the accumulated amounts of arsenic, arsenic compounds, and cadmium, and the resistances thereto, thereby economically cleaning the environment in an environmentally friendly manner is possible.

Description

technical field

[0001] The present invention relates to compositions for transporting phytochelatins comprising DNA molecules encoding the ABCC (Multidrug Resistance-Associated Proteins (MRP)) subfamily of ATP-binding cassette (ABC) transporters in plants. Background technique

[0002] Arsenic (As) has been widely used in medical, industrial and agricultural applications. In the field of medicine, arsenic (As) has been used in the treatment of diseases such as syphilis, trypanosomiasis or amoebic dysentery. In agricultural applications, arsenic-containing herbicides such as disodium methyl arsenate (DSMA) have been used to control weeds and harmful insects. However, arsenic (As) is a highly toxic environmental pollutant known to cause a variety of health-related problems. Arsenic (As) contamination of groundwater has been reported in some countries, such as China, Thailand, and the United States, where mining operations are active, as well as Bangladesh and India. Contami...
