Abstract
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.
Claims4
A sorghum hybrid wherein germplasm of said sorghum hybrid comprises a polynucleotide:
- a) having at least 95% sequence identity to SEQ ID NO:
- 1, provided that said polynucleotide encodes a modified sorghum acetolactate synthase comprising a valine to isoleucine amino acid substitution at position 531 and a tryptophan to leucine amino acid substitution at position 545;
- or
- b) encoding a polypeptide sequence having acetolactate synthase activity, wherein said polypeptide sequence has at least 95% sequence identity to SEQ ID NO:
- 2, provided that said polypeptide sequence comprises a valine to isoleucine amino acid substitution at position 531 and a tryptophan to leucine amino acid substitution at position 545;
- wherein the expression of said polynucleotide confers to said sorghum hybrid increased resistance to inhibition by one or more acetolactate synthase herbicides compared to a sorghum hybrid not expressing said polynucleotide.
