The following species are recognized:

Structure[edit]

Viruses in Badnavirus are non-enveloped, with bacilliform geometries. The diameter is around 30 nm, with a length of 130 nm. Genomes are circular and non-segmented, around 7.2kb in length.

Life Cycle[edit]

Viral replication is nuclear. Entry into the host cell is achieved by penetration into the host cell. Replication follows the DNA strand displacement model. DNA-templated transcription is the method of transcription. The virus exits the host cell by nuclear pore export. Plants serve as the natural host. Transmission routes are mechanical.
