Abstract
The present invention provides a plant or plant part comprising a polynucleotide encoding a wildtype or mutant TriA polypeptide, the expression of said polynucleotide confers to the plant or plant part tolerance to herbicides.
Claims30
A plant, plant part, or plant cell comprising a polynucleotide encoding a mutant TriA polypeptide having at least 80% identity to the sequence of SEQ ID NO:
- 2, wherein the amino acid sequence of the mutant TriA polypeptide differs from the wildtype amino acid sequence of a TriA polypeptide at one or more amino acids corresponding to positions 70, 71, 88, 91, 92, 96, 126, 128, 155, 157, 167, 220 of SEQ ID NO:
- 2, wherein the expression of said polynucleotide confers to the plant, plant part, or plant cell tolerance to herbicides.
A plant, plant part, or plant cell comprising a polynucleotide encoding a mutant TriA polypeptide wherein the mutant TriA polypeptide comprises the sequence of SEQ ID NO:
- 2, wherein the amino acid sequence differs from the wildtype amino acid sequence at one or more amino acids corresponding to positions 70, 71, 88, 91, 92, 96, 126, 128, 155, 157, 167, 220 of SEQ ID NO:
- 2.
A method for controlling weeds at a locus for growth of a plant, the method comprising:
- (a) applying an herbicide composition comprising herbicides to the locus;
- and (b) planting a seed at the locus, wherein the seed comprises a polynucleotide encoding a mutant TriA polypeptide having at least 80% identity to the sequence of SEQ ID NO:
- 2, wherein the amino acid sequence of the mutant TriA polypeptide differs from the wildtype amino acid sequence of a TriA polypeptide at one or more amino acids corresponding to positions 70, 71, 88, 91, 92, 96, 126, 128, 155, 157, 167, 220 of SEQ ID NO:
- 2, wherein the seed is capable of producing a plant that comprises in at least some of its cells the polynucleotide operably linked to a promoter operable in plant cells, the promoter capable of expressing the mutant TriA polypeptide encoded by the polynucleotide, the expression of the mutant TriA polypeptide conferring to the plant tolerance to herbicides.
An isolated and/or recombinantly produced and/or synthetic nucleic acid molecule comprising:
- a nucleic acid molecule encoding a mutated TriA polypeptide having 80% or more identity with the amino acid sequence of the TriA polypeptide sequence of SEQ ID NO:
- 2, wherein the amino acid sequence of the mutated TriA polypeptide differs from the wildtype amino acid sequence of a TriA polypeptide at one or more amino acids corresponding to positions 70, 71, 88, 91, 92, 96, 126, 128, 155, 157, 167, 220 of SEQ ID NO:
- 2, and
- wherein expression of the nucleic acid molecule in a plant cell, a plant or a part thereof confers increased herbicide tolerance or resistance thereto, as compared to a corresponding, non-transformed, wild type plant cell, a plant or a part thereof.
An isolated, recombinant and/or chemically synthesized mutant TriA polypeptide comprising an amino acid sequence having at least 80% identity to the sequence of SEQ ID NO:
- 2, wherein the amino acid sequence of the mutant TriA polypeptide differs from the wildtype amino acid sequence of a TriA polypeptide at one or more amino acids corresponding to positions 70, 71, 88, 91, 92, 96, 126, 128, 155, 157, 167, 220 of SEQ ID NO:
- 2.
