Patent

CA 2542451

Plants are disclosed that express a cytosine DNA methyltransferase and that can be used to confer an altered seed phenotype, e.g., an increase in seed weight. Also disclosed are plants in which expression of an endogenous cytosine DNA methyltransferase is inhibited and that exhibit an altered seed phenotype, e.g., an increase in seed weight. Also disclosed are nucleic acids and polypeptides suitable for conferring such phenotypes.

L'invention concerne des plantes qui expriment une cytosine-ADN-méthyltransférase et qui permettent d'obtenir un phénotype de semences modifié, comme p. ex. une augmentation du poids des semences. L'invention concerne également des plantes dans lesquelles l'expression l'une cytosine-ADN-méthyltransférase est inhibée et qui présentent un phénotype de semences modifié, comme p. ex. une augmentation du poids des semences. L'invention concerne en outre des acides nucléiques et de polypeptides permettant d'obtenir de tels phénotypes.
