摘要:
The present invention relates to novel Pcr family genes which confer tolerance to heavy metals to organisms. More particularly, the present invention relates to novel Pcr family genes which confer tolerance to cadmium. Organisms transformed with any of the Pcr genes thereby have improved resistance to and increased level of toxic materials. Soil and water contaminated with heavy metals can be cleaned in an environment-friendly and economical manner by growing the Pcr-transformed organism, especially a plant transformed with the Pcr gene.
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.

摘要:
A composition for transportation of phytochelatin including two DNA molecule encoding two members of 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 from cytosol, and also reducing it from translocation from the root to the shoot of a plant. Therefore, the DNA molecule can be useful 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 useful to develop inedible plants 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 economic manner.

The invention relates to a transgenic plant or yeast comprising a DNA molecule encoding fungal ATP-binding cassette (ABC) transporter protein, which confers resistance to, and/or accumulation of heavy metals and herbicides. The invention also relates to methods of producing transgenic plants expressing fungal YHL035C protein, which can be used for removing heavy metals and herbicides from polluted soil or water.
摘要:
The present invention relates to an isolated DNA encoding fungal MRP (multidrug resistance associated protein) subfamily of ATP-binding cassette (ABC) transporter protein which confers organisms with resistance to and/or accumulation of toxic materials such as heavy metals and herbicides, vectors containing the isolated DNA, and organisms transformed with the isolated DNA. Organisms transformed with the fungal MRP subfamily of ABC transporters of the present invention can be used for remediation of environment polluted with toxic materials. For example, the transformed plants can be used for cleaning polluted soil or water, and thereby providing an environmentally-friendly way to remediate polluted resources with low cost.
