Bromoviridae is a family of viruses.[1] Plants serve as natural hosts. There are six genera in the family.[2][3]

Taxonomy

The following genera are assigned to the family:[2]

Structure

Viruses in the family Bromoviridae are non-enveloped, with icosahedral and bacilliform geometries. The diameter is around 26-35 nm.[2][3]

Genus Structure Symmetry Capsid Genomic arrangement Genomic segmentation
Ilarvirus Icosahedral T=3 Non-enveloped Linear Segmented
Anulavirus Icosahedral T=3 Non-enveloped Linear Segmented
Bromovirus Icosahedral T=3 Non-enveloped Linear Segmented
Oleavirus Icosahedral T=1 Non-enveloped Linear Segmented
Alfamovirus Varies Non-enveloped Linear Segmented
Cucumovirus Icosahedral T=3 Non-enveloped Linear Segmented

Genomes are linear and segmented, tripartite.[2][3]

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, 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.[2][3]

Genus Host details Tissue tropism Entry details Release details Replication site Assembly site Transmission
Ilarvirus Plants None Viral movement; mechanical inoculation Viral movement Cytoplasm Cytoplasm Mechanical inoculation: insects; contact

Oleavirus Plants None Viral movement; mechanical inoculation Viral movement Cytoplasm Cytoplasm Mechanical inoculation: insects; contact
Alfamovirus Plants None Viral movement; mechanical inoculation Viral movement Cytoplasm Cytoplasm Mechanical inoculation: insects
Cucumovirus Plants None Viral movement; mechanical inoculation Viral movement Cytoplasm Cytoplasm Mechanical inoculation: insects; contact
