Abstract:
A method of eliminating transmission of a transgene of interest contained within the genome of a plant, wherein the method eliminates the production of pollen containing the transgene of interest by said plant and thereby prevents transmission of the transgene of interest by pollination with another plant, said method comprising:a) producing a transformed plant that is hemizygotic but not homozygotic or heterozygotic for a nucleic acid construct comprising a pollen-specific promoter operably linked to a suicide coding region in close physical proximity to a transgene of interest; b) growing the plant in step a) wherein said plant only produces pollen lacking said transgene of interest; and c) allowing the pollen from the plant grown in step b) to pollinate the same or another plant of the same species; wherein said pollen does not contain the transgene of interest and transmission of said transgene of interest to said other plant is eliminated.
