Members of the genus Plasmopamonavirus are distinct from those of other genera by phylogenetic analysis of the RdRP gene (Figure 5.Mymonaviridae) with <32% amino acid sequence identity for the L protein. The genome is a single molecule of linear, negative-sense RNA of about 6.2 kb with one ORFs. Virions, antigenicity, and biology have not been reported. The virus belonging to the species Plasmopamonavirus plasmoparae was detected by high-throughput sequencing in the mycelial mass of oomycetes collected from plant lesions.
Species demarcation criteria
Members of different species in the genus differ by >30% in nucleoprotein amino acid sequence and by >30% in their coding-complete or complete genome nucleotide sequence.
