Description and Significance

Genome Structure

The genome is non-segmented and contains a single molecule of circular double-stranded DNA. The complete genome is 7200-7600 nucleotides long. The genome has terminally redundant sequences that have direct terminal repeats and are reiterated internally in inverted form. (source: ICTVdB)

Virion Structure of a Badnavirus

The virions of a badnavirus consist of a non-enveloped, elongated, icosahedral capsid. The capsid is bacilliform and the capsid shells of the virions are composed of multiple layers. Virions are either 95-130 nm or 60-900 nm in length, and 24-30-35 nm in diameter. (source: ICTVdB)
