Taxonomy
Group: ssRNA(+)
Structure
Viruses in Botrexvirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12-13 nm, with a length of 720 nm. Genomes are linear, around 7kb in length. The genome codes for 5 proteins.
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 is the method of transcription. The virus exits the host cell by tripartite non-tubule guided viral movement. Fungi serve as the natural host.
