Patent

CA 2675255

The invention provides transgenic plants that exhibit increased resistance to nematode infection by virtue of overexpression of a gene that encodes trehalase in nematode-induced syncytia. Expression vectors comprising trehalase-encoding polynucleotides and methods of employing such vectors to increase nematode resistance of plants are also provided.

L'invention concerne des plantes transgéniques qui présentent une résistance accrue à une infection par des nématodes en raison d'une surexpression d'un gène qui code pour la tréhalase dans les syncytia induites par des nématodes. L'invention concerne également des vecteurs d'expression comprenant des polynucléotides codant pour la tréhalase ainsi que méthodes d'utilisation de tels vecteurs afin d'augmenter la résistance de plantes aux nématodes.
