PHYTOPATHOGENIC DNA VIRUS RESISTANT TRANSGENIC PLANTS AND SEEDS AND METHODS FOR OBTAINING SAME

摘要

Use of nucleotide sequences produced by mutation (also known as mutant nucleotide sequences) of nucleotide sequences present in a pathogenic DNA virus genome in plants. The mutant nucleotide sequences comprise one or more mutations capable of producing a dominant negative phenotype for the replication of the pathogenic virus, and/or its diffusion in a plant, and/or its spread from one plant to another, especially through vectors such as insects, the mutant nucleotide sequences being capable of fully or partially inhibiting the replication and/or diffusion and/or spread of the pathogenic virus. The invention is for producing phytopathogenic DNA virus resistant or tolerant transgenic plants.
