Mivirus

Mivirus is a genus of negative-strand RNA viruses which infect arthropods.[1] Member viruses have nonsegmented and bisegmented genomes.[2] It is the only genus in the family Chuviridae, which is the only family in Jingchuvirales. There are thirty species in the genus.[3]

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] Chuviridae gets its name from 楚 (Chǔ), meaning Chǔ state, added to -viridae the suffix for a virus family.[4] Jingchuvirales is from 荆楚 (Jīngchǔ), a synonym for Chǔ, along with -virales the suffix for a virus order.[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]
