  • Method for delivery of proteins to plant cells
    Patent number: 6800791
    Abstract: The invention relates to the use of a modified Agrobacterium to deliver proteins directly to plant cells. Proteins of interest are delivered to the plant host in the form of a fusion protein with the Agrobacterium virulence protein VirF. Nucleotide sequences encoding such fusion proteins of VirF and a protein of interest are provided. Also provided are bacteria modified to comprise such fusion proteins of VirF and a protein of interest. Methods of introducing such fusion proteins into a plant host are provided. The invention finds use in facilitating plant transformation and particularly in the bio-engineering of desirable traits into crop plants.

  • Wuschel (WUS) gene homologs
    Publication number: 20040166563
    Abstract: This invention relates to isolated polynucleotides encoding WUS polypeptides. The invention further provides isolated WUS polypeptides. The invention also provides methods of using the polynucleotides to modulate the level of WUS, improve transformation efficiency, to stimulate plant cell growth, including stem cells, to stimulate organogenesis, to stimulate somatic embryogenesis, to induce apomixis, and to provide a positive selection for cells comprising the polynucleotide. The invention also relates to cells, plants and seeds comprising the polynucleotides of the invention or produced by the methods of the invention.
