Species[1]

Bromovirus is a genus of viruses, in the family Bromoviridae.[3] Plants serve as natural hosts. There are currently six species in this genus including the type species Brome mosaic virus.[1][4]

Taxonomy

Group: ssRNA(+) Order: Unassigned

[1]

Structure

Viruses in the genus Bromovirus are non-enveloped, with icosahedral geometries, and T=3 symmetry. The diameter is around 26 nm. Genomes are linear and segmented, tripartite.[1][4]

Bromovirus Icosahedral T=3 Non-enveloped Linear Segmented

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. Plants serve as the natural host. Transmission routes are mechanical and contact.[1][4]
