Mivirus

Mivirus is a genus of negative-strand RNA viruses which infect arthropods.[1] Member viruses have nonsegmented and bisegmented genomes.[2] There are nine species in the genus.[3]

Mivirus
Virus classification
(unranked): Virus
Realm: Riboviria
Kingdom: Orthornavirae
Phylum: Negarnaviricota
Class: Monjiviricetes
Order: Jingchuvirales
Family: Chuviridae
Genus: Mivirus

Etymology

The name Mivirus derives from 芈 (Mǐ), the ancestral name of King Zhuang of Chu during the Spring and Autumn period, along with -virus, the suffix for a virus genus.[4]

Genome
The differing genome organizations in the family Chuviridae

Miviruses have nonsegmented and bisegmented genomes which are linear. Some member viruses may have circular genomes.[1][2]
