Designation of potyvirus genera: a question of perspective and timing.

Abstract

It may be premature to subdivide the Potyviridae into genera (Bymovirus, Potyvirus, Rymovirus) since definitive serological and vector interrelationships between them remain to be established. Monogenic proposals for classifying Potyviridae should also be viewed askance until their practical value in agricultural settings can be demonstrated.
