Abstract
The present invention provides a maize plant wherein the growth and development of said plant is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, at levels which normally inhibit the growth and development of maize, wherein said tolerance is conferred by an altered acetyl coenzyme A carboxylase (ACCase) tolerant of inhibition by said herbicide at levels which normally inhibit the activity of an unaltered ACCase.
Claims5
A method of imparting herbicide tolerance to maize plants comprising forming a maize callus tissue culture of plant cells;
- subjecting said maize callus tissue culture to a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof;
- selecting for plant cells from said maize callus tissue culture which comprise a gene encoding for an acetyl coenzyme A carboxylase (ACCase) which is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, at levels which normally inhibit the activity of ACCase;
- and generating maize plants from said selected maize callus tissue culture of plant cells, wherein said cells comprise said gene encoding an acetyl coenzyme A carboxylase (ACCase) which is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, at levels which normally inhibit the activity of ACCase.
