Emaravirus is a genus of negative-strand RNA viruses which infect plants. The plant virus group is the sole genus in the family Fimoviridae.[1]

Structure

Virions of this genus are between 80 and 100 nm and consists of an enveloped ribonucleocapsid that exhibits helical symmetry.[citation needed]

Genome

The genomes are segmented, consisting of four strands of negative-sense single-stranded RNA.[citation needed]

Phylogenetics

Emaravirus has the closest phylogenetic relationship with members of the genera Orthotospovirus and Orthobunyavirus. The 3' and 5' ends of the genomic RNAs are complementary (similar to viruses of the Bunyaviricetes class), with the sequence 5'-AGUAGUGUUCUCC-3' at the 5' terminus and 5'-GGAGUUCACUACU-3' at the 3' terminus. However, the number of genome segments and gene sequences distinguishes emaraviruses from bunyaviruses and tenuiviruses.[citation needed]

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[2][3]
