Necrosis in Solanum tuberosum stems infected with potato virus Y by grafting
This work examined the distribution of necrosis on stems of two cultivars of potato (Ania, Glada) with different
levels of resistance to PVY infection. Potato virus Y particles and/or cytoplasmic (CI) and amorphous inclusions
(AI) were identified in insert and offshoot potato cells of susceptible cv. Glada. Cytoplasmic inclusions were not
observed in insert and offshoot stems of resistant cv. Ania, although there were numerous deformations, degeneration
and tissue necrosis. It was found that (1) necrotic reactions were the form of plant cell response for both
the PVY-resistant and susceptible cultivars, (2) development of necrosis in vascular tissue did not prevent the
pathogen from spreading outside the necrotic region in the less resistant cultivar (Glada), and (3) extreme resistance
to PVY in potato plants, determined by the Rysto gene, was manifested in the absence of virus particles and
cytoplasmic inclusions in infected plant cells
