Isolated polynucleotides that encode acetohydroxyacid synthase small subunit (AHASS) polypeptides, and the amino acid sequences encoded by these polynucleotides, are described. The present invention provides expression cassettes and plant expression vectors comprising the polynucleotides encoding the AHASS polypeptides or AHASS fusion polypeptides. Also provided are plants, seeds, and host cells transformed with the polynucleotides, expression cassettes, or expression vectors of the present invention. The invention further provides methods of using the polynucleotides of the present invention to enhance the AHAS activity and to enhance tolerance of plants to herbicides.
