ICTV Virus Taxonomy Profile: Ourmiavirus

J Gen Virol. 2017 Feb;98(2):129-130. doi: 10.1099/jgv.0.000725.

Abstract

Members of the plant virus genus Ourmiavirus are characterized by having non-enveloped bacilliform virions with a series of discrete lengths from 30 to 62 nm composed of a single coat protein (CP). The genome consists of three positive-sense single-stranded RNAs, each encoding a single protein. The RNA-dependent RNA polymerase (RdRp) has closest similarity to that of viruses from the family Narnaviridae; the movement protein (MP) is similar to the MPs of tombusviruses; the CP shows limited similarity to the CPs of several plant and animal viruses. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the genus Ourmiavirus, which is available at www.ictv.global/report/ourmiavirus.
