Patent ID: 7250554

Claim:
A method of modifying a trait of a selected plant by stably integrating only a desired polynucleotide into the genome of said plant, comprising (a) transforming said plant with said desired polynucleotide, wherein said desired polynucleotide consists essentially of (i) a nucleic acid sequence that is native to the selected plant, native to a plant from the same species as the selected plant, or native to a plant that is sexually interfertile with said selected plant, wherein (ii) the desired polynucleotide does not contain foreign DNA that is not from the selected plant species or a plant that is sexually compatible with the selected plant species and (iii) the desired polynucleotide does not comprise a nucleotide sequence that is identical in nucleotide sequence to an Agrobacterium T-DNA border sequence; (b) selecting plant cells comprising only said desired polynucleotide in the genome; and (c) obtaining a stably transformed plant from the selected transformed plant cells, wherein the transformed plant contains only the desired polynucleotide stably integrated into its genome and wherein the stably transformed plant exhibits a trait that is modified in comparison to the selected plant.
