106); virions contain 5% RNA by weight. RNA molecules have poly (A) tracts at their 3
-ends. A genome-linked protein of Mr 24 103 is covalently linked at or near the 5 terminus.

Type Species |
(PVY) |
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 S20w is 150-160S; density in CsCl is 1.31 g/cm3; E0.1%1 cm, 260 nm = 2.4-2.7.
Virions contain a single molecule of linear, positive sense ssRNA, about 9.7 kb in size (Mr 3.0-3.5 106); virions contain 5% RNA by weight. RNA molecules have poly (A) tracts at their 3-ends. A genome-linked protein of Mr 24 103 is covalently linked at or near the 5 terminus.
Virions contain a single CP, Mr 30 to 47 103 in size. The CP of most isolates of the type species, PVY, contains 267 amino acids.
Genome Organization and Replication
Potyvirus genomes are approximately 9.7 kb in size (Fig. 2).
Virions are moderately immunogenic; there are serological relationships among many members. One monoclonal antibody reacts with most aphid-transmitted potyviruses. The CP amino acid sequence homology among aphid-transmitted viruses is 40-70%. Some species are serologically related to species in the genera Rymovirus and Bymovirus.
Many individual viruses have a narrow host range, but a few infect 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.
