Ilarvirus

Ilarvirus is a genus of positive-strand RNA viruses in the family Bromoviridae.^[1] Plants serve as natural hosts. There are 36 species in this genus.^[2][3]

Structure

Viruses in the genus Ilarvirus are non-enveloped, with icosahedral and quasi-spherical geometries, and T=3 symmetry. The diameter is around 29 nm. Genomes are linear and have three segments.^[2][3]

Life cycle

Viral replication is cytoplasmic and lysogenic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive-strand RNA virus replication model in the cytoplasm. Positive strand 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 inoculation by insects and plant to plant contact.^[2][3]
