Complete and partial genome sequences of two isolates of an unusual new plant virus, designated Donkey orchid symptomless virus (DOSV) were identified using a high-throughput sequencing approach. The virus was identified from asymptomatic plants of Australian terrestrial orchid  Diuris longifolia  (Common donkey orchid) growing in a remnant forest patch near Perth, western Australia. DOSV was identified from two  D. longifolia  plants of 264 tested, and from at least one plant of 129  Caladenia latifolia  (pink fairy orchid) plants tested. Phylogenetic analysis of the genome revealed open reading frames (ORF) encoding seven putative proteins of apparently disparate origins. A 69-kDa protein (ORF1) that overlapped the replicase shared low identity with MPs of plant tymoviruses ( Tymoviridae ). A 157-kDa replicase (ORF2) and 22-kDa coat protein (ORF4) shared 32% and 40% amino acid identity, respectively, with homologous proteins encoded by members of the plant virus family  Alphaflexiviridae . A 44-kDa protein (ORF3) shared low identity with myosin and an autophagy protein from Squirrelpox virus. A 27-kDa protein (ORF5) shared no identity with described proteins. A 14-kDa protein (ORF6) shared limited sequence identity (26%) over a limited region of the envelope glycoprotein precursor of mammal-infecting Crimea-Congo hemorrhagic fever virus ( Bunyaviridae ). The putative 25-kDa movement protein (MP) (ORF7) shared limited (27%) identity with 3A-like MPs of members of the plant-infecting  Tombusviridae  and  Virgaviridae . Transmissibility was shown when DOSV systemically infected  Nicotiana benthamiana  plants. Structure and organization of the domains within the putative replicase of DOSV suggests a common evolutionary origin with ‘potexvirus-like’ replicases of viruses within the  Alphaflexiviridae  and  Tymoviridae , and the CP appears to be ancestral to CPs of allexiviruses ( Alphaflexiviridae ). The MP shares an evolutionary history with MPs of dianthoviruses, but the other putative proteins are distant from plant viruses. DOSV is not readily classified in current lower order virus taxa.
