Complete genome sequences of anemone mosaic virus and ranunculus mild mosaic virus isolated from anemone imported from the Netherlands into Japan.

Anemone mosaic virus (AnMV) and ranunculus mild mosaic virus (RanMMV) infect anemone plants, which exhibit characteristic mosaic patterns on their leaves. Employing next-generation sequencing of plant material imported from the Netherlands, the complete genome sequences of these two viruses were determined for the first time. AnMV and RanMMV have 9698 and 9537 nucleotides (nt), respectively, excluding the poly(A) tail. They share 80.0%/82.0% and 98.0%/97.0% nt/amino acid (aa) sequence identity, which is above the species demarcation value, in the previously reported AnMV and RanMMV coat protein sequences, but they share 69.0%/70.0% nt/aa sequence identity or less with other potyviruses in all 10 mature protein coding regions of the genome. Additionally, phylogenetic analysis confirmed the relationship of the AnMV and RanMMV genome sequences to previously reported partial sequences and placed them within the genus Potyvirus. These results show that these two viruses represent separate species within the genus Potyvirus.
