Group: Group IV ((+)ssRNA)
Order: Tymovirales
Family: Betaflexiviridae
Genus: Tepovirus
Type Species
  • Potato virus T

Tepovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants as well as some other root and tuber crops in the andes serve as natural hosts. There is currently only one species in this genus: the type species Potato virus T.[1][2]


Group: ssRNA(+)



Viruses in Tepovirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12 nm. Genomes are linear, around 6.5kb in length. The genome codes for 3 proteins.[1]

Life Cycle[edit]

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Plants as well as some other root and tuber crops in the Andes serve as the natural host. Transmission routes are seed borne and pollen associated.[1]
