Estimating the term…
The present invention relates to a new plant breeding process. The process improves the agronomic performance of crop plants by using genetic material that is also used in classical breeding. Instead of sexually recombining entire genomes at random, as is done in classical breeding, specific genetic elements are rearranged in vitro and inserted back into individual plant cells. Plants obtained through this new plant breeding process do not contain foreign nucleic acid but only contain nucleic acid from the plant species selected for transformation or plants that are sexually compatible with the selected plant species. Plants developed through this new plant breeding process are provided. In particular, potato plants displaying improved tuber storage and health characteristics are provided.
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;
