Genus: Potyvirus

Genus: Potyvirus

Distinguishing features

The largest genus in the family contains viruses transmitted by aphids in a non-persistent manner.



Virions are flexuous filaments, 680–900 nm long and 11–13 nm wide, with helical symmetry and a pitch of about 3.4 nm. Particles of some viruses are longer in the presence of divalent cations than in the presence of EDTA.

Physicochemical and physical properties

Virion Sedimentation coefficient S20,w is 137–160S; density in CsCl is 1.31 g cm−3; Extinction coefficient E0.1%1 cm, 260 nm=2.4–2.7.

Nucleic acid

Virions contain a single molecule of linear, positive sense ssRNA, about 9.7 kb in size; virions contain 5% RNA by weight.


Virions contain a single CP, 30–47 kDa in size. The CP of most isolates of the type species, Potato virus Y, contains 267 aa.

Genome organization and replication

The genome is organized as described in Figure 2.Potyviridae.


Virions are moderately immunogenic; there are serological relationships among many members. Some monoclonal antibodies react with most aphid-transmitted potyviruses. The CP aa sequence identity among aphid-transmitted viruses is 40–70%. Some viruses are serologically related to viruses in the genera Rymovirus and Bymovirus.


Many individual viruses have a narrow host range, but a few infect plant species in up to 30 host families. The viruses are transmitted by aphids in a non-persistent manner and are transmissible experimentally by mechanical inoculation. Some isolates are inefficiently transmitted by aphids and others are not transmissible by aphids at all. This is apparently due to mutations within the helper component and/or CP cistrons. Some viruses are seed-transmitted.

Derivation of names

Poty: from the type species Potato virus Y
