摘要: Orchid fleck virus (OFV) represents a rhabdovirus with unique bipartite genome. OFV genetic diversity at the whole genome level has not been described. Using partial sequence of RNA1, we have determined that several isolates derived from orchids in Japan belong to two genetically distant subgroups: subgroup I, members which are distributed worldwide but previously known Asia, and II, is commonly Japan. However, complete analysis novel Japanese I isolate revealed although its RNA1 differs considerably those II isolates, RNA2 almost identical them. Based on phylogenetic recombination analyses, reassortment events were predicted occur between subgroups including other unseen strains. Our data show contributes diversities rhabdoviruses occurrence may be geographically constrained.
