Phytopathogenic geminivirus resistant transgenic plants and seeds and methods for obtaining same by introduction of mutated C1 gene

摘要

Nucleotide sequences produced by mutation (also known as mutant nucleotide sequences) of C1 nucleotide sequences present in a pathogenic geminivirus genome in plants with one or more mutations capable of producing a dominant negative phenotype for the replication of the pathogenic virus, its diffusion in a plant, 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 for producing phytopathogenic geminivirus resistant or tolerant transgenic plants.
