Taxonomy

The following species are assigned to the genus, with their scientific name and common name:^[4]

• Anulavirus ALMMV, Amazon lily mild mottle virus
• Anulavirus GLPV, Grapevine line pattern virus
• Anulavirus PZSV, Pelargonium zonate spot virus

Structure

Viruses in the genus Anulavirus have icosahedral and Quasi-spherical geometries, and T=3 symmetry. The diameter is around 25-35 nm. Genomes are linear and segmented, tripartite.^[2][3]

Life cycle

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, using the internal initiation model of subgenomic rna transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Pelargonium serve as the natural host. Transmission routes are mechanical.^[2][3]
