Isolated polynucleotide, a modified polymer encoded from large subunit octanoacetic acid, method for producing herbicide tolerant transgender plants, and procedures for controlling ideal plants, departmental archives 1990-13.
The invention provides nucleic acids encoding mutants of the acetohydroxyacid synthase (AHAS) large subunit comprising at least two mutations, for example double and triple mutants, which are useful for producing transgenic or non-transgenic plants with improved levels of tolerance to AHAS-inhibiting herbicides. The invention also provides expression vectors, cells, plants comprising the polynucleotides encoding the AHAS large subunit double and triple mutants, plants comprising two or more AHAS large subunit single mutant polypeptides, and methods for making and using the same.LA INVENCIÓN PROPORCIONA ÁCIDOS NUCLEICOS QUE CODIFICAN MUTANTES DE LA SUBUNIDAD GRANDE DE LA ACETOHIDROXIÁCIDO-SINTASA AHAS QUE COMPRENDE MODIFICACIONES, QUE SON ÚILES PARA PRODUCIR PLANTAS TRANSGÉNICAS CON NIVELES MEJORADOS DE TOLERANCIA A LOS HERNICIDAS QUE INHIBEN IA AHAS. LA INVENCIÓN TAMBIÉN PROPORCIONA VECTORES DE EXPRESIÓN, CÉLULAS, PLANTAS QUE COMPRENDEN LOS POLINUCLEÓTIDOS MODIFICADOSQUE CODIFICAN IA SUBUNIDAD GRANDE DE AHAS.
