  • Title: Sequence data as the major criterion for potyvirus classification.
    Author: Ward CW, McKern NM, Frenkel MJ, Shukla DD.
    Journal: Arch Virol Suppl; 1992; 5():283-97. PubMed ID: 1450751.
    Abstract:
    Recent knowledge of the structure of the potyvirus particle and its components appears to have resolved what was thought to be an intractable problem of plant virology. This review describes how coat-protein and gene sequence data can be used to provide an hierarchical classification of potyviruses. This classification puts the aphid and non-aphid-transmitted potyviruses into a single family, divides this family into four genera that correspond to the four modes of vector transmission, discriminates distinct potyvirus species from strains, and provides a basis for the formation of subgroups composed of closely related species within a genus.
