title: Complete nucleotide sequence analysis of a Korean strain of hepatopancreatic parvovirus (HPV) from Fenneropenaeus chinensis.
abstract: Hepatopancreatic parvovirus (HPV) of shrimp is distributed worldwide and the entire genome of Thailand and Indian strains (PmDNV) and one Australian strain (PmergDNV) have now been reported. The complete nucleotide sequence of a HPV strain isolated from the fleshy prawn Fenneropenaeus chinensis in Korea (FcDNV) was determined and compared to previously reported sequences. The entire genome of FcDNV contains 6,336 nucleotides, with 40% G+C content, which is the biggest of the known HPV strains. The HPV genome has three open reading frames (ORFs) with a slight overlap between the first and second ORFs. The three ORFs encode the NS2 and NS1 proteins and VP that consist of 425, 578, and 820 amino acids, respectively. Among the three proteins, the NS1 protein shows the highest sequence similarity to the NS1 protein of other known HPV strains, followed by the NS2 protein and the VP protein. Phylogenetic analyses showed that HPV can be grouped into three genotypes, as previously reported, and FcDNV can be grouped as genotype I, with HPV strains isolated in Madagascar and Tanzania. The nucleotide sequences of the noncoding regions at the 5'- and 3'-ends of the plus-strand genome showed a Y-shaped hairpin structure and simple hairpin structure, respectively.
