  • Patent number: 8207399
    Abstract: The present invention relates to a method for producing syringyl lignin in gymnosperms. The production of syringyl lignin in gymnosperms is accomplished by genetically transforming a gymnosperm genome, which does not normally contain genes which code for enzymes necessary for production of syringyl lignin, with DNA which codes for enzymes found in angiosperms associated with production of syringyl lignin. The expression of the inserted DNA is mediated using host promoter regions in the gymnosperm.
    Type: Grant
    Filed: June 24, 2010
    Date of Patent: June 26, 2012
    Assignee: Arborgen Inc.

  • Patent number: 7754869

The production of syringyl lignin in gymnosperms is accomplished by genetically transforming a gymnosperm genome, which does not normally contain genes which code for enzymes necessary for production of syringyl lignin, with DNA which codes for enzymes found in angiosperms associated with production of syringyl lignin. The expression of the inserted DNA is mediated using host promoter regions in the gymnosperm. In addition, genetic sequences which code for gymnosperm lignin anti-sense mRNA may be incorporated into the gymnosperm genome in order to suppress the formation of the less preferred forms of lignin in the gymnosperm such as guaiacyl lignin.

  • Patent number: 7288409
    Abstract: A method of concurrently introducing multiple genes to plants and trees is provided. The method includes an Agrobacterium-mediated gene delivery system by which multiple genes together with a single selectable marker gene are simultaneously transferred and inserted into the genome of plants, including trees.
