We have isolated three naturally occurring strains of Turnip crinkle virus (TCV) that break resistance in Di-17 Arabidopsis. Two mutations in the N terminus of the TCV coat protein, D4N and P5S, were shown to confer this phenotype. Thus, this region of the coat protein is involved in eliciting resistance responses in Arabidopsis.
