virus, isolated or recombinant nucleic acid or totv specific fragment thereof, expression vector, polynucleotide, isolated or recombinant polypeptide, antigen, antibody, methods for producing an antibody against a virus, for identifying a viral isolate as a virus, for detecting the presence of a virus in a sample, to identify a plant that is resistant to a virus, and to produce a plant that is resistant to a virus; and, uses of a virus, isolated or recombinant nucleic acid or totv specific fragment of the expression virus, polynucleotide, isolated polypeptide or virus, to identify a viral isolate with virus, to detect the presence of a virus in a sample, to identify a plant that is resistant to a virus, and to produce a plant that is resistant to a virus, and, uses of a virus, and at an attenuated form of a virus

摘要

The invention relates to the field of virology. The invention provides an isolated plant virus named Tomato Marchitez virus (ToMarV), and components thereof. The invention further relates to methods of producing a ToMarV-resistant plant comprising the steps of identifying a ToMarV-resistant donor plant, crossing said ToMarV-resistant donor plant with a recipient plant, and selecting from an offspring plant a resistant plant.
