Ghabrivirales
Life cycle of S. cerevisiae virus L-A
Virus classification
(unranked):	Virus
Realm:	Riboviria
Kingdom:	Orthornavirae
Phylum:	Duplornaviricota
Class:	Chrymotiviricetes
Order:	Ghabrivirales

Ghabrivirales is an order of double-stranded RNA viruses. It is the only order in the class Chrysmotiviricetes. The name of the class is a portmanteau of member families: chrysoviridae, megabirnaviridae, and totiviridae; and -viricetes which is the suffix for a virus class. The name of the order derives from Said Ghabrial, a pioneering researcher who studied viruses in this order, and -virales which is the suffix for a virus order. ^[1]
