Description and Significance

Genome Structure

The genome is not segmented and contains a single molecule of circular double-stranded DNA that forms a covalently closed circle. (source: ICTVdb Descriptions)

Virion Structure of a Guttaviridae

The virions of guttaviridae are poorly characterized and consist of a coat, a core, a nucleocapsid, and fibers. The virus capsid is enveloped. Virions are droplet-shaped with a beehive-like ribbed surface pattern with protrusions that are densely covered by a beard of long fibers at its pointed end. The virions measure 70-95 nm in diameter and are 110-185 nm long. The core is oblong and is released when a filamentous matrix is broken; that might be the DNA molecule.
