Complete nucleotide sequence of Velvet tobacco mottle virus isolate K1

Abstract

Velvet tobacco mottle virus (VTMoV) infects the native Australian plant Nicotiana velutina, which is endemic to central Australia. This virus is included in the genus Sobemovirus based on virion morphology and serological relationships. We report here the full genome sequence of VTMoV, attained using a genome-walking strategy with both degenerate and specific primers. This sequence confirms that VTMoV is a sobemovirus, with the same open reading frame (ORF) organisation as other described sobemoviruses. The VTMoV sequence is closest to those sobemoviruses isolated from monocotyledonous plants, although the narrow host range of VTMoV is limited to dicotyledonous plants.
