Title: Herbicide resistance genes

Assignee: Corteva Agriscience LLC (Current Assignee), Dow AgroSciences LLC (Original Assignee)

Inventors: Terry Wright, Justin Lira, Donald Merlo, Nicole Arnold

Filing Date: October 7, 2016

Issue Date: March 16, 2021

Abstract: The patent describes novel aryloxyalkanoate dioxygenase (AAD) genes and the proteins they encode, which provide resistance to phenoxy auxin herbicides (such as 2,4-D) and/or aryloxyphenoxypropionate (AOPP) herbicides (such as quizalofop and haloxyfop). The invention includes plants containing these genes, methods of controlling weeds using these plants and herbicides, and methods for selecting transformed plants using the AAD gene as a selectable marker.

Plain-language overview of each independent claim:

• Claim 1: This claim covers a transgenic plant cell that is resistant to both 2,4-D and aryloxyphenoxypropionate (AOPP) herbicides. This resistance is achieved by having a nucleic acid that encodes an aryloxyalkanoate dioxygenase (AAD-1) polypeptide, where this polypeptide has at least 95% amino acid sequence identity to SEQ ID NO: 11. The plant cell is further defined by the specific codons used in the nucleic acid sequence, which are "plant-optimized" for expression in a plant. The claim specifies that this AAD-1 polypeptide has the ability to degrade both 2,4-D and AOPP herbicides.

• Claim 17: This claim describes a plant that contains the transgenic plant cell of Claim 1. This means the plant itself possesses the specified genetic modification for resistance to 2,4-D and AOPP herbicides.

• Claim 18: This claim is directed to a seed that produces the plant of Claim 17. Therefore, the seed carries the genetic modification for herbicide resistance.

• Claim 19: This claim covers a method for controlling weeds in a field where the plant of Claim 17 is growing. The method involves applying an effective amount of at least one phenoxy auxin herbicide (e.g., 2,4-D) and an effective amount of at least one AOPP herbicide to the field. Because the plant is resistant, the herbicides control the weeds without significantly damaging the desired crop.

• Claim 20: This claim focuses on a method for selectively controlling weeds in a field. It specifies applying an effective amount of at least one phenoxy auxin herbicide and at least one AOPP herbicide to the field planted with the seed of Claim 18. This method allows for weed control while the herbicide-resistant plants grow.
