  • Transgenic organism expressing fungal MRP-like ABC transporters
    Patent number: 7358417
    Abstract: 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.
    Type: Grant
    Filed: October 16, 2002
    Date of Patent: April 15, 2008
    Assignees: POSCO, POSTECH Foundation
    Inventors: Won Yong Song, Young Yeul Yang, YoungSook Lee, InWhan Hwang, Eun Woon Noh, Young Im Choi, Eun Hwa Jeong, Enrico Martinoia
  • PCR family genes which confer tolerance to heavy metals
    Patent number: 7307199
    Abstract: The present invention relates to novel Pcr family genes that confer tolerance to heavy metals to plants and microorganisms. More particularly, the present invention relates to novel Pcr family genes that confer tolerance to cadmium. The invention also relates to plant and microorganisms transformed with any of the Pcr genes thereby having improved resistance to and increased level of toxic materials, and methods of removing heavy metals from contaminated soil and water contaminated by growing the Pcr-transformed plants on the contaminated soils and water.
    Type: Grant
    Filed: April 12, 2005
    Date of Patent: December 11, 2007
    Assignees: POSCO, POSTECH Foundation, POSTECH Academy-Industry Foundation
    Inventors: YoungSook Lee, Won Yong Song, InWhan Hwang, Do Young Kim, Eun Hwa Jeong, Eun Woon Noh, Young Im Choi, Enrico Martinoia, Joohyun Lee, Dongwoo Kim, Esther Vogt, Donghwan Shim, Kwan Sam Choi
  • Novel Pcr family genes which confer tolerance to heavy metals
    Publication number: 20060230468
    Abstract: 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.

  • Transgenic organism epressing fungal mrp-like abc transporters
    Publication number: 20050091709
    Abstract: 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.
