The potato virus Y [potyvirus] group is comprised of a number of distinctive members, estimated to be between 100 and 150 dependent on the criteria used in classification (Edwardson, 1974; Hollings and Brunt, 1981). Although each member has a rather restrictive host range, the large number of putative members make these viruses ubiquitous pathogens present in most agricultural settings. As such, over the past 5 years they have become one of the more intensively studied plant virus groups. Using molecular biological approaches, our understanding of potyvirus gene structure, function, and expression has increased dramatically.
