Carlavirus, also known as "Carnation latent virus group" is a genus of virus that infects plants. It contains thirty-five described species and twenty-nine tentative species..[1]

The virions are non enveloped, filamentous, 470-1000 nanometers (nm) or more in length and 12-13 nm in diameter.
The linear 5.8-9 kilobase genome is positive single stranded RNA. The 3’ terminus is polyadenylated. In some species the 5’ end is capped. The genome encodes 3 to 6 proteins including a coat protein located at the 3' end and an RNA dependent RNA polymerase located at the 5' end of the genome.
Infection is at times spread by aphids in a semi-persistent mode, that is, the vector is infective for a number of hours.(Pimentel) Some species are transmitted by Bemisia tabaci in a semi-persistent mode or through the seed.[1] Most species infect only a few hosts and cause infections with few or no symptoms, for example, American hop latent virus and lily symptomless virus. Some, such as blueberry scorch virus and poplar mosaic virus, cause serious illnesses. (Foster)
