Genes conferring herbicide resistance
View Patent ↗Compositions and methods for conferring herbicide resistance to plants, plant cells, tissues and seeds are provided. Compositions comprising a coding sequence for a polypeptide that confers resistance or tolerance to glyphosate herbicides are provided. The coding sequences can be used in DNA constructs or expression cassettes for transformation and expression in plants. Compositions also comprise transformed plants, plant cells, tissues, and seeds. In particular, isolated nucleic acid molecules encoding glyphosate resistance proteins are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed. In particular, the present invention provides for isolated nucleic acid molecules comprising nucleotide sequences encoding the amino acid sequence shown in SEQ ID NO:2 or the nucleotide sequence set forth in SEQ ID NO:1.

a) a nucleic acid molecule comprising the nucleotide sequence of SEQ ID NO:1 or a complement thereof;
b) a nucleic acid molecule comprising a nucleotide sequence having at least 95% sequence identity to the nucleotide sequence of SEQ ID NO:1 or a complement thereof;
c) a nucleic acid molecule that encodes a polypeptide having the amino acid sequence of SEQ ID NO:2; and
d) a nucleic acid molecule that encodes a polypeptide having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:2.
2. A vector comprising the nucleic acid molecule of claim 1 .
3. An isolated host cell that contains the vector of claim 2 .
4. The host cell of claim 3 that is a bacterial host cell.
5. The host cell of claim 3 that is a plant host cell.
6. A plant having stably incorporated into its genome a DNA construct comprising at least one nucleotide sequence encoding a glyphosate resistance protein selected from the group consisting of:

c) a nucleic acid molecule that encodes a polypeptide having the amino acid sequence of SEQ ID NO:2; and
d) a nucleic acid molecule that encodes a polypeptide having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:2.
7. The plant of claim 6 , wherein said plant is selected from the group consisting of corn, alfalfa, wheat, soybean, rice, Brassica, sunflower, cotton, peanut, sorghum, millet and tobacco.
8. The plant of claim 6 , wherein said plant is a monocot.
9. The plant of claim 6 , wherein said plant is a dicot.
10. Seed of the plant according to claim 6 .
11. A plant cell having stably incorporated into its genome a DNA construct comprising at least one nucleotide sequence encoding a glyphosate resistance protein selected from the group consisting of:
a) a nucleic acid molecule comprising the nucleotide sequence of SEQ ID NO:1 or a complement thereof;
