Abstract

A new virus was isolated from a bellflower (Campanula takesimana) plant showing veinal mottle symptoms, and its complete genome sequence was determined. The viral genome consists of a positive-sense single-stranded RNA of 8,259 ribonucleotides. Electron microscopic observation revealed that the viral genome is packaged as a filamentous particle with an average length of approximately 760 nm. BLAST searches of protein databases showed that the encoded polyprotein has a maximum amino acid sequence identity of 34.1% (with 95% coverage) to that of the isolate AD of Chinese yam necrotic mosaic virus (CYNMV; genus Macluravirus). Phylogenetic analysis and comparison of the encoded amino acid sequences with those of other viruses demonstrated that the identified virus shows minimal sequence similarity to known viruses and should therefore be considered a member of a new genus in the family Potyviridae. The name bellflower veinal mottle virus (BVMoV) is proposed for this new virus.
