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.

Abstract

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.
