Virus classification
Group: Group IV ((+)ssRNA)
Genus: Polemovirus
Type Species
  • Poinsettia latent virus

Polemovirus is a genus of viruses. Commercial cultivars of euphorbia pulcherrima serve as natural hosts. There is only one species in this genus: the type species Poinsettia latent virus.[1][2]


Group: ssRNA(+)



Viruses in Polemovirus are non-enveloped, with icosahedral geometries, and T=3 symmetry. Genomes are linear and non-segmented.[1]

Life cycle

Viral replication is cytoplasmic, and is lysogenic. 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. The virus exits the host cell by tubule-guided viral movement. Commercial cultivars of euphorbia pulcherrima serve as the natural host.[1]
