Patent

CA 2636771

The present invention relates to the production of a non-transgenic plant resistant or tolerant to a herbicide of the phosphonomethylglycine family, e.g., glyphosate. The present invention also relates to the use of a recombinagenic oligonucleobase to make a desired mutation in the chromosomal or episomal sequences of a plant in the gene encoding for 5-enol pyruvylshikimate-3-phos.rho.hate synthase (EPSPS). The mutated protein, which substantially maintains the catalytic activity of the wild-type protein, allows for increased resistance or tolerance of the plant to a herbicide of the phosphonomethylglycine family, and allows for the substantially normal growth or development of the plant, its organs, tissues or cells as compared to the wild-type plant irrespective of the presence or absence of the herbicide. Additionally the present invention relates to mutant E. coli cells that contain mutated EPSPS genes.

La présente invention concerne la production d'un végétal non transgénique résistant à ou tolérant un herbicide de la famille des phosphonométhylglycines, p. ex. le glyphosate. La présente invention concerne également l'emploi d'une oligonucléobase recombinogène pour produire une mutation voulue dans les séquences chromosomiques ou épisomiques d'un végétal dans le gène encodant la 5-énol pyruvylshikimate-3-phos.rho.hate synthase (EPSPS). La protéine mutée qui conserve sensiblement l'activité catalytique de la protéine de type sauvage permet une résistance accrue ou une tolérance du végétal à un herbicide de la famille des phosphonométhylglycines, ainsi que sa croissance sensiblement normale ou son développement sensiblement normal, ceux de ses organes, tissus ou cellules par rapport au végétal de type sauvage sans tenir compte de la présence ou de l'absence de l'herbicide. De plus, la présente invention concerne des cellules mutantes de E. coli qui contiennent les gènes EPSPS mutés.
