It has been suggested that amalgaviruses have evolved via recombination between viruses with double-stranded and negative-strand RNA genomes.[6] Phylogenetic analysis indicates that the amalgavirus RdRp forms a sister clade to the corresponding RdRp protein of partitiviruses (Partitiviridae) which have segmented (bipartite) dsRNA genomes and infect plants, fungi and protists.[1][2][4][6] By contrast, the putative capsid protein of amalgaviruses is homologous to the nucleocapsid proteins of negative-strand RNA viruses of the genera Phlebovirus (Bunyaviridae) and Tenuivirus.[6]
Taxonomy
The family Amalgaviridae has two genera and ten species:[3]
