Plant virus cDNA

摘要

A method is disclosed for detecting RNA viral infections in plants comprising the isolation of an RNA molecule, e.g., from alfalfa mosaic virus (AMV), production of full-length cDNA transcripts, cloning into plasmids and propgation of the recombinant plasmid. This recombinant DNA plasmid is utilized diagostically to test a plant for infection by a virus, e.g., AMV.
