    Abstract: A sorghum seed comprising in its genome at least one polynucleotide encoding a polypeptide having an alanine to threonine substitution at position 93 of the sorghum AHAS protein large subunit. The plant has increased resistance to one or more herbicides, for example from the imidazolinone group, as compared to wild-type sorghum plants. The sorghum plant may comprise in its genome, one, two, three or more copies of a polynucleotide encoding a mutated large subunit of sorghum AHAS or a sorghum AHAS polypeptide of the invention. In this context, the sorghum plant may be tolerant to any herbicide capable of inhibiting AHAS enzyme activity. For example, the sorghum plant may be tolerant to herbicides of the imidazolinones type, such as imazethapyr, imazapir, and imazapic or to herbicides of the sulfonylurea group.

    Abstract: The subject invention provides novel plants that are not only resistant to 2,4-D and other phenoxy auxin herbicides, but also to aryloxyphenoxypropionate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention alone or “stacked” together with another herbicide resistance gene, preferably a glyphosate resistance gene, so as to provide broader and more robust weed control, increased treatment flexibility, and improved herbicide resistance management options. More specifically, preferred enzymes and genes for use according to the subject invention are referred to herein as AAD (aryloxyalkanoate dioxygenase) genes and proteins. No ?-ketoglutarate-dependent dioxygenase enzyme has previously been reported to have the ability to degrade herbicides of different chemical classes and modes of action.
