Özet
An outbreak in northwestern Turkey of prunus necrotic ringspot virus (PNRSV, genus Ilarvirus, family Bromoviridae) was sampled in 2016-2018. Gene sequences from these isolates, together with all of the gene sequence data for this virus in the GenBank database (>300 non-recombinant coat protein (CP) genes and 20 complete genomic sequences) were analysed to determine the relationship of the Turkish PNRSV isolates to those from other parts of the world. Phylogenetic and population genetic methods independently showed that the most recent common ancestor of the world PNRSV population was probably American, not Eurasian. PNRSV has spread to Turkey on several occasions, as its CP sequences are among the terminal branches of three of the most sampled CP phylogroups. The complete PNRSV genome consists of three segments (RNA1, RNA2, and RNA3), with the larger two encoding replicases and the smallest encoding the movement protein and the CP. One quarter of the RNA1 and RNA2 genes were recombinants. The phylogenies of the CP and MP genes (i.e., different regions of RNA3) were closely correlated but did not correlate with those of RNA1 and RNA2, indicating that some of the isolates were reassortants. However, the non-reassortant ancestor could not be identified, probably because none of the complete genome sequences were from isolates from the basal CP phylogroups. Our results emphasize the importance of strict quarantine, both international and local, for the world's stone fruit crops.
