Patent

CA 2535132

The present invention relates to transgenic plants resistant to parasites that their normal life cycle includes feeding on the plant cytoplasm, including insects, nematodes and fungi, wherein the plants are engineered to produce small interfering RNAs (siRNAs) capable of silencing a parasite specific gene. Particularly the parasite gene is a stage-specific gene, more particularly a gene involved in essential, early developmental stages of the parasite in or on the plant.

La présente invention concerne des plantes transgéniques résistantes à des parasites dont le cycle de vie normal consiste à se nourrir du cytoplasme des plantes, tels que des insectes, des nématodes et des champignons. Lesdites plantes sont modifiées génétiquement en vue de la production de petits ARN interférents (siARN) capables d'inactiver un gène spécifique du parasite. Plus particulièrement, le gène du parasite est un gène spécifique d'étape, et notamment un gène impliqué dans les étapes de croissance précoces essentielles du parasite dans ou sur la plante.
