The resistance mechanism to potato virus Y (PVY) in pepper plants homozygous for the recessive resistance allele ya (pr21) was investigated. The results of the fluorescence immunochemical analysis of protoplasts prepared from virus-inoculated plants or virus-inoculated protoplasts indicate that this resistance is due to impaired cell-to-cell movement of the virus, rather than to an interference with virus replication
