Docket Number: 12401
Serial Number: 9911088

Technology Description: 


Agricultural Research Service (ARS) scientists in California have developed a method to improve plants by adding multiple traits simultaneously, which can be targeted to very specific locations.  This method provides a more convenient way to insert new DNA into different parts of the plant genome.  ARS’s technique will allow plant breeders and regulators to quickly and easily identify newly-introduced traits—thus expediting breeding programs.  This method also makes it easier to remove all transgenic DNA using a single deletion step.  The selective removal of certain types of transgenic traits may have practical use as well as public appeal.  A large investment is required in genomic research in major commodity crops.  This technique could allow many new improved traits to become available sooner.

The plant biotechnology industry would benefit from this invention, especially those engineering major commodity crop plants.  ARS researchers are seeking a commercial partner to test and refine the strategy for their crops of interest.
