Abstract

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 transgene 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. Methods and compositions for improving yield are further provided.
