摘要： Compositions and methods related to transgenic glyphosate/ALS inhibitor- tolerant maize plants are provided. Specifically, the present invention provides maize plants having a DP-098140-6 event which imparts tolerance to glyphosate and at least one ALS-inhibiting herbicide. The maize plant harboring the DP-098140-6 event at the recited chromosomal location comprises genomic/transgene junctions having at least the polynucleotide sequence of SEQ ID NO: 5 and/or 6. The characterization of the genomic insertion site of the DP-098140-6 event provides for an enhanced breeding efficiency and enables the use of molecular markers to track the trans gene insert in the breeding populations and progeny thereof. Various methods and compositions for the identification, detection, and use of the maize DP-098140-6 events are provided.

摘要： Methods and compositions are provided related to improved plants that are tolerant to more than one herbicide. Particularly, the invention provides plants that are tolerant of glyphosate and are tolerant to at least one ALS inhibitor, and methods of use thereof. The glyphosate/ALS inhibitor-tolerant plants comprise a polynucleotide that encodes a polypeptide that confers tolerance to glyphosate and a polynucleotide that encodes an ALS inhibitor-tolerant polypeptide. In specific embodiments, a plant of the invention expresses a GAT polypeptide and an HRA polypeptide. Methods to control weeds, improve plant yield, and increase transformation efficiencies are provided.
