Abstract
Potato genotypes that differ in their resistance to Andean Potato Mottle Virus (APMoV) were analyzed regarding their response to stress induced by APMoV inoculation. Using 1- and 2-D electrophoretic analysis, a substantial difference was observed between the patterns of induced / reduced polypeptides in the leaves of susceptible plants (cv. Delta) and resistant ones (cv. Bintje). Western blot analysis indicates the presence of a virus-inducible chitinase in the susceptible cultivar.
