The first complete sequence and genome structure of daphne virus Y

Abstract

From Daphne odora Thunb., an ornamental shrub in the Republic of Korea, a potyvirus was identified that has an RNA genome of 9,448 nucleotides (excluding the 3'-terminal poly(A) tail) encoding a polyprotein of 3,065 amino acids, with nine putative protease cleavage sites producing ten proteins. Since this potyvirus shared the highest nucleotide sequence identity (91 %; query coverage 5 %) with the available partial sequence of daphne virus Y (DVY) from New Zealand (EU179854), it was considered a Korean isolate of DVY. This is the first molecular characterization of the complete genome sequence of a DVY isolate.
