Abstract
The invention provides transgenic or non-transgenic plants with improved levels of tolerance to AHAS-inhibiting herbicides. The invention also provides nucleic acids encoding mutants of the acetohydroxyacid synthase (AHAS) large subunit, expression vectors, plants comprising the nucleic acids encoding the AHASL subunits containing one, two, or more mutations, plants comprising such AHASL subunit mutant nucleic acids, methods for making and using the same, and methods of controlling weeds.

1-105. (canceled)
An isolated, recombinant, mutagenized, or synthetic nucleic acid molecule encoding a Brassica acetohydroxyacid synthase large subunit (AHASL) protein comprising a mutation at a position corresponding to position A122 of SEQ ID NO:23 and a mutation at a position corresponding to position S653 of SEQ ID NO:23.
An isolated, recombinant, mutagenized, or synthetic nucleic acid molecule encoding a Brassica napus acetohydroxyacid synthase large subunit (AHASL) protein comprising a mutation at a position corresponding to position A122 of SEQ ID NO:23.
A Brassica plant comprising a mutagenized Brassica napus nucleic acid molecule encoding an herbicide tolerant Brassica acetohydroxyacid synthase large subunit (AHASL) protein comprising a mutation at a position corresponding to position A122 of SEQ ID NO:23, wherein the Brassica plant is resistant to at least one AHAS-inhibiting herbicide.
A Brassica seed capable of producing a Brassica plant comprising a mutagenized Brassica napus nucleic acid molecule encoding a Brassica acetohydroxyacid synthase large subunit (AHASL) protein having a mutation at a position corresponding to position A122 of SEQ ID NO:23.
