Characterization of Prunus Necrotic Ringspot Virus and Cherry Virus A Infecting Myrobalan Rootstock

Prunus necrotic ringspot virus (PNRSV) and cherry A (CVA) are two viruses that mainly infect plants of the genus Prunus. Full-length sequences these viruses, collected in Czech Republic from cerasifera plants, were obtained via HTS sequencing. Phylogenetic analyses based on NJ method Splitstree tools showed PNRSV isolate (ON088600-ON088602) is a divergent other molecular groups, sharing less than 97% pairwise nucleotide identity with members groups. The CVA (ON088603) belonged to subgroup III-2, clustered isolates non-cherry hosts, shared highest (99.7%) an Australian origin.
