Acetolactate synthase herbicide resistant sorghum
View Patent ↗The present invention provides for compositions and methods for producing sorghum crop plants that are resistant to herbicides. In particular, the present invention provides for sorghum plants, plant tissues and plant seeds that contain altered acetolactate synthase (ALS) genes and proteins that are resistant to inhibition by herbicides that normally inhibit the activity of the ALS protein.
1. A seed of a sorghum hybrid, wherein representative seeds have been deposited under ATCC No. PTA-7999, wherein said seed comprises a polynucleotide comprising the nucleotide sequence represented by SEQ ID NO: 1, provided that said nucleotide sequence comprises a guanine to adenine nucleic acid substitution at position 1641 and a guanine to thymine nucleic acid substitution at position 1684.
2. A sorghum plant grown from the seed of claim 1 .
3. Plant tissue obtained from the sorghum plant of claim 2 .
4. Grain obtained from the sorghum plant of claim 2 , wherein said grain comprises the polynucleotide comprising the nucleotide sequence represented by SEQ ID NO: 1, provided that said nucleotide sequence comprises a guanine to adenine nucleic acid substitution at position 1641 and a guanine to thymine nucleic acid substitution at position 1684.
5. The seed of claim 1 , wherein said seed is coated with one or more acetoacetate synthase herbicides.
6. The seed of claim 5 , wherein said one or more acetoacetate synthase herbicides are selected from the group consisting of sulfonylureas, imidazolinones, triazolopyrimidines, and pyrimidinylthiobenzoates.
7. The seed of claim 6 , wherein the sulfonylurea herbicide is selected from the group consisting of nicosulfuron, rimsulfuron, and metsulfuron-methyl.
