Patent

CA 2328058

The present invention relates to methods to alter the expression of a target gene in a plant using sense and antisense RNA fragments of the gene. The sense and antisense RNA fragments are capable of pairing and forming a double-stranded RNA molecule, thereby altering the expression of the gene. The present invention also relates to plants, their progeny and seeds derived thereof, obtained using a method of the present invention.

Dans la présente invention, on divulgue des méthode pour modifier l'expression d'un gène cible dans une plante à l'aide de fragments d'ARN sens et antisens du gène. Lesdits fragments peuvent s'apparier et former une molécule d'ARN double brin, modifiant ainsi l'expression du gène. Dans la présente invention, on divulgue également des plantes, leur descendance et les graines dérivées de ces dernières, obtenues en utilisant la méthode de la présente invention.
