Abstract
The complete genome sequence of a previously undescribed virus isolated from a yacon plant exhibiting necrotic mottle, chlorosis, stunting, and leaf malformation symptoms in Gyeongju, Korea, was determined. The genome of this virus consists of one circular double-stranded DNA of 7661 bp in size. The genome contained four open reading frames (ORFs 1 to 4) on the plus strand that potentially encode proteins of 26, 32, 234, and 25 kDa. Protein BLAST analysis showed that ORF3, which is the largest ORF, has 45 % amino acid sequence identity (with 89 % coverage) to the ORF3 of fig badnavirus 1 (FBV-1), a recently identified badnavirus. Phylogenetic analysis provided further evidence that the virus identified in this study is probably a member of a new species in the genus Badnavirus. The name yacon necrotic mottle virus (YNMoV) is proposed for this new virus.
