A new negative-strand RNA (nsRNA) virus genome was discovered in Edgeworthia chrysantha Lindl. This virus, tentatively named "Edgeworthia chrysantha mosaic-associated virus" (ECMaV), has a bipartite genome that comprises (i) a nsRNA1, encoding the viral RNA-dependent RNA polymerase (RdRp), and (ii) an ambisense RNA2, coding for the putative movement protein (MP) and nucleocapsid protein (NP), with the open reading frames separated by a long AU-rich intergenic region (IR). Sequence comparisons and phylogenetic analysis showed that the RdRp is closely related to those of other recently discovered plant-infecting nsRNA viruses in the new genus Coguvirus and that ECMaV can be classified as a member of a novel species.
