Abstract
The present invention provides herbicide-tolerant plants. The present invention also provides methods for controlling the growth of weeds by applying an herbicide to which herbicide-tolerant plants of the invention are tolerant. Plants of the invention may express an acetyl-Coenzyme A carboxylase enzyme that is tolerant to the action of acetyl-Coenzyme A carboxylase enzyme inhibitors
Claims30
A method for obtaining a rice plant having tolerance to tepraloxydim and to 100 g ai/ha cycloxydim, the method comprising:
- providing a rice seed containing a non-transgenic, mutagenized, rice acetyl-Coenzyme A carboxylase (ACCase) nucleic acid having a sequence obtained by an induced, random mutagenesis method and encoding a rice plastidic ACCase, the ACCase having, as a result of said mutagenesis, an isoleucine-to-leucine substitution at amino acid position 1,792 of SEQ ID NO:2;
- and growing from the seed a rice plant expressing said ACCase nucleic acid, wherein said rice plastidic ACCase confers said tolerances to the rice plant.
A commercial rice plant of a commercial rice line, said plant exhibiting tolerance to tepraloxydim and to 100 g ai/ha cycloxydim, wherein said plant comprises and expresses a non-transgenic, mutagenized, rice acetyl-Coenzyme A carboxylase (ACCase) nucleic acid having a sequence obtained by an induced, random mutagenesis method and encoding a rice plastidic ACCase, the ACCase having, as a result of said mutagenesis, an isoleucine-to-leucine substitution at amino acid position 1,792 of SEQ ID NO:2, the rice plastidic ACCase conferring said tolerances to the rice plant.
A seed of a commercial rice plant, the rice plant exhibiting tolerance to tepraloxydim and to 100 g ai/ha cycloxydim, wherein said seed comprises a non-transgenic, mutagenized, rice acetyl-Coenzyme A carboxylase (ACCase) nucleic acid having a sequence obtained by an induced, random mutagenesis method and encoding a rice plastidic ACCase, the ACCase having, as a result of said mutagenesis, an isoleucine-to-leucine substitution at amino acid position 1,792 of SEQ ID NO:2, the rice plastidic ACCase conferring said tolerances to the rice plant grown from said seed.
A method for controlling weeds comprising:
- a) providing a commercial rice plant of a commercial rice line, said plant exhibiting tolerance to tepraloxydim and to 100 g ai/ha cycloxydim, wherein said plant comprises and expresses a non-transgenic, mutagenized, rice acetyl-Coenzyme A carboxylase (ACCase) nucleic acid having a sequence obtained by an induced, random mutagenesis method and encoding a rice plastidic ACCase, the ACCase having, as a result of said mutagenesis, an isoleucine-to-leucine substitution at amino acid position 1,792 of SEQ ID NO:2;
- the rice plastidic ACCase conferring said tolerances to the rice plant;
- and
- b) contacting the plant and weeds in the vicinity thereof with an effective amount of an herbicidal composition comprising an ACCase-inhibiting herbicide, wherein the effective amount would inhibit the growth of a corresponding wild-type rice plant.
