Structure

Viruses in ''Aureusvirus'' are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The diameter is around 30 nm. Genomes are linear, around 4.4kb in length.

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 premature termination model of subgenomic RNA transcription is the method of transcription. Translation takes place by leaky scanning, and suppression of termination. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. Transmission routes are mechanical, seed borne, and contact.
