Turnip ringspot virus (TuRSV) has been proposed to be a member of a new species in the genus Comovirus. Its remarkable host-range similarity to radish mosaic virus (RaMV) may have led to its misrecognition in the past. Findings from both sequence analysis and serological tests support the assignment of TuRSV to a new comovirus species. In addition, phylogenetic analysis suggests that the two genome segments of some TuRSV isolates have a heterogeneous origin.

The intraspecies variability of capsid proteins of five viruses of the genus Comovirus was established. Inclusion of both capsid proteins to the sequence analysis reduces some uncertainties about species/strains demarcation criteria in the Comovirus genus. New approach is proposed for discrimination of Turnip ringspot virus as a separate species.
