Plant Satellite Viruses (Albetovirus, Aumaivirus, Papanivirus, Virtovirus)

Mart Krupovic


Satellite viruses are a polyphyletic group of viruses encoding structural components of their virions, but incapable of completing the infection cycle without the assistance of a helper virus. Satellite viruses have been described in animals, protists and plants. Satellite viruses replicating in plants have small icosahedral virions and encapsidate positive-sense RNA genomes typically carrying a single gene for the capsid protein. Thus, for genome replication these viruses necessarily depend on helper viruses which can belong to different families. Plant satellite viruses are classified into genera Albetovirus, Aumaivirus, Papanivirus and Virtovirus. This article describes the diversity and properties of these viruses.
