Patent ID: 7851670

Claim:
A method for selecting a transformed soybean plant cell comprising the steps of: a) contacting a population of plant cells comprising a transgenic soybean plant cell transformed with a polynucleotide encoding dicamba monooxygenase with medium comprising auxin-like herbicide in an amount that inhibits the growth of cells from the population lacking the polynucleotide, wherein the polynucleotide comprises a nucleic acid sequence selected from: (1) a nucleic acid sequence encoding the polypeptide of SEQ ID NO: 6, (2) a nucleic acid sequence comprising the sequence of SEQ ID NO: 5, and (3) a nucleic acid sequence encoding a polypeptide with at least 90% sequence identity to the polypeptide of SEQ ID NO:6, wherein the polypeptide has dicamba monooxygenase activity; and b) selecting the transformed soybean plant cell from the population of plant cells based on tolerance exhibited by the transformed cell to the auxin-like herbicide further wherein: said polynucleotide encoding dicamba monooxygenase is operatively linked to a chloroplast transit peptide coding sequence.
