Patents by Inventor Richard H. Smeltzer

Richard H. Smeltzer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.

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: 4354327
    Abstract: A tissue culture method for the asexual propagation of pine trees is described and claimed. The method involves promoting adventitious buds from pine seeds by inoculating decoated seeds that have been previously stimulated to germinate in a culture medium. The method enhances adventitious bud formation and is operationally more practical than currently reported methods in that it is neither time consuming nor labor intensive. Also, novel culture media are described and claimed which employ the interaction of the growth regulators benzylaminopurine and abscisic acid.
