The complete nucleotide sequence of sweet potato C6 virus: a carlavirus lacking a cysteine-rich protein

Arch Virol. 2013 Jun;158(6):1393-6. doi: 10.1007/s00705-013-1614-x. Epub 2013 Jan 30.


The complete nucleotide sequence of a sweet potato virus, first identified two decades ago as virus "C-6", was determined in this study. Sequence similarity and phylogenetic analysis clearly place it as a member of a distinct species within the genus Carlavirus, family Betaflexiviridae. Its genome structure was typical for that of other carlaviruses except that the ORF for the cysteine-rich protein was replaced by an ORF encoding a predicted protein with no similarity to any known protein.
