Taxonomy
Group: ssRNA(+)
Structure
Viruses in Macanavirus are non-enveloped, with icosahedral and spherical geometries, and T=3 symmetry. The diameter is around 28 nm. Genomes are linear, around 4kb in length.
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 premature termination 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.
