  • Production of polyhydroxyalkanoate in plants
    Patent number: 7341856
    Abstract: The invention relates to the genetic manipulation of plants to produce polyhydroxyalkanoate, particularly in the peroxisomes. Methods for producing such polymers in plants and host cells are provided. Such methods find use in producing biodegradable thermoplastics in plants and other organisms. Nucleotide molecules, expression cassettes, and genetically manipulated host cell, plants, plant tissues, and seeds are also provided.
    Type: Grant
    Filed: July 17, 2006
    Date of Patent: March 11, 2008
    Assignees: Pioneer Hi-Bred International, Inc., E.I. du Pont de Nemours and Company
    Inventors: Kanwarpal S. Dhugga, Chun Ping Li, Jian G. Dong, William D. Hitz, Matthias Liebergesell, Scott E. Nichols, Kristen K. Briggs
