The responses of a collection of Arabidopsis thaliana eco-types to mechanical inoculation with turnip mosaic poty-virus were assessed. The virus induced characteristic severe symptoms of infection in systemically infected plants. Resistance was found in four ecotypes: Bay-0, Di-0, Er-0, and Or-0. Enzyme-linked immunosorbent assay results of the resistant ecotypes suggested that ecotypes Di-0, Er-0, and Or-0 actually consist of mixed genotypes with resistances acting at different levels in the virus life cycle. Another form of resistance was found in ecotype Bay-0, for which several lines of evidence indicated an interference with viral cell-to-cell movement in the inoculated leaves.
