Amalgaviruses (Amalgaviridae)

The family Amalgaviridae, part of the realm Riboviria was recognized by the International Committee on Taxonomy of Viruses (ICTV) in 2014. The family includes viruses infecting plants and fungi (yeasts) with a non-segmented, bicistronic dsRNA genome of 3.1–3.5 kbp and is currently composed of two genera: Amalgavirus and Zybavirus. The 5′ proximal ORF of the viruses encodes the putative coat protein (CP) whereas the product of 3′ proximal cistron, with typical RNA-dependent RNA polymerase (RdRp) motifs, is possibly expressed as a fusion with the CP via programmed +1 ribosomal frameshift.
