The Brassica napus differential line 165 is resistant to infection by Turnip mosaic virus (TuMV) isolates belonging to pathotypes 1 and 3. Nucleotide sequences of resistance-breaking mutants of pathotype 1 (UK 1), pathotype 3 (CHN 12), and wild-type isolates have been determined. When the mutations identified were introduced into an infectious clone of UK 1, a single mutation in the viral P3 protein induced a hypersensitive (necrotic) response in inoculated leaves of line 165 plants.
