DISEASE RESISTANT TRANSGENIC PLANTS

摘要

Transgenic plants transformed with a cucumovirus 2b gene or active fragment thereof exhibit resistance to diseases caused by infectious pathogens, such as viruses. Expression of the 2b gene causes activation of hypersensitive response and expression of pathogenicity-related proteins in plants that are incapable of such a response to certain pathogens. Transformation of a wide variety of plants with expression vectors in which the cucumovirus 2b gene is operably linked to a plant-active promoter renders the plant resistant to pathogenic infection.
