Ceratobium mosaic virus (CerMV; species Potyvirus ceratobii) has only been recorded from the east coast of Australia, where it infects native Dendrobium and allied orchid genera. Very little is known about this virus, although based on its classification as a potyvirus, it likely is transmitted in a non-persistent manner by aphids. When first discovered, only a RT-PCR amplicon covering the NIb and coat protein coding regions and 3’ untranslated region of the viral genome was sequenced, which at the time was sufficient for official recognition of this virus as a novel species. However, the standard of evidence now required for taxonomic proposals is a complete or near complete genome sequence. In this report, we present the complete genome sequence of an isolate of CerMV from New South Wales, allowing a more comprehensive analysis of its classification and phylogeny.
