Drosophila X virus

Drosophila X virus is a virus that infects fruit flies of the genus Drosophila and is commonly used to study innate immunity in the common model organism Drosophila melanogaster. The viral capsid is roughly hexagonal and icosahedrally symmetrical. The genome of the virus consists of two linear, double-stranded RNA molecules. As a result, the virus is often used to study RNA interference as a mechanism of viral immunity in Drosophila.
