NOVEL MUTATION INVOLVED IN INCREASED TOLERANCE TO IMIDAZOLINONE HERBICIDES IN PLANTS Russian patent published in 2014 - IPC A01H1/00 A01H5/00 C12N15/29 C12N15/63 

FIELD: chemistry.

SUBSTANCE: invention relates to biochemistry, particularly to a plant, having high resistance to an AHAS-inhibiting herbicide, which includes at least one Shiloh-8 IMI nucleic acid, parts thereof, a plant cell and seeds. Described is a nucleic acid which encodes a polypeptide which increases herbicide resistance of a plant. Disclosed are an expression cassette and a plant transformation vector which include said nucleic acid. Described are methods of controlling weeds growing near a plant having high resistance to an AHAS-inhibiting herbicide. Disclosed is a method of producing a plant having high resistance to an AHAS-inhibiting herbicide, as well as a method of increasing AHAS activity in a plant. Described is a method of selecting a cell transformed by a vector containing IMI nucleic acid. Also disclosed is a method of increasing resistance to an AHAS-inhibiting herbicide and a weed control method which includes treatment with an AHAS-inhibiting herbicide.

EFFECT: invention enables to obtain a plant which is resistant to an AHAS-inhibiting herbicide, which provides effective control of weeds growing near said plant.
