摘要

Method of modeling based on the structure, DNA isolated by a proteu00ecna variant of synthesis of acid acetohidroxi (AHAs) vector DNA, cell, seed, proteu00ecna of AHAS variant.Method for providing resistance to the herbicide to a cell, plant.Methods for the production of proteu00ecna of AHAS resistant to herbicide and to control weeds in a safram and cell and plant transformed with a DNA ".Including methods of modeling based on structures for the preparation of variants acetohidroxi acid synthase (AHAs),Including the show resistance selectively increased in relation to herbicides, such as herbicides and herbicide imidazolina inhibitors to AHAS.The invention encompasses isolated DNAs encoding such variants, vectors comprising the DNA.And methods to produce the polypeptide variants and herbicide resistant plants containing specific genetic mutations of AHAS.Are provided also methods to control weeds in crops.
