Abstract
Methods and compositions for treatment and prevention of Potexvirus disease in plants are provided, including methods and compositions employing double-stranded RNA polynucleotides and a transfer agent. Further provided are compositions for treatment or prevention of Potexvirus disease in plants, and methods for reducing expression of a Potexvirus gene and for identifying polynucleotides useful in modulating gene expression in plant viruses.
Claims12
A method of treatment or prevention of a Pepino Mosaic Virus (PepMV) infection in a plant, the method comprising topically applying to said plant a composition comprising a double-stranded RNA polynucleotide and a transfer agent, wherein the double-stranded RNA polynucleotide consists of a first polynucleotide sequence that consists of at least 21 contiguous nucleotides of SEQ ID NO:
- 14 and a second polynucleotide sequence that is completely complementary to the first polynucleotide sequence, and wherein the symptoms of viral infection or development of symptoms are reduced or eliminated in said plant relative to a plant not treated with said composition when grown under the same conditions.
A composition comprising a double-stranded RNA polynucleotide and a transfer agent, wherein said double-stranded RNA polynucleotide consists of a first polynucleotide sequence that consists of at least 21 contiguous nucleotides of SEQ ID NO:
- 14 and a second polynucleotide sequence that is completely complementary to the first polynucleotide sequence, and wherein topical application of the composition to a plant reduces or eliminates the symptoms of PepMV infection or development in said plant relative to a plant not treated with said composition when grown under the same conditions.
