Abstract:
In this study, samples collected from eight sweet cherry trees in northern Greece were analyzed by high-throughput sequencing for the presence of viruses. Bioinformatic analysis revealed the presence of divergent isolates of cherry latent virus 1 (CLV-1), a recently identified trichovirus in a sweet cherry accession imported into the USA from the Republic of Georgia. The complete genome sequences of seven CLV-1 isolates were determined, and phylogenetic analysis indicated that they belonged to a separate clade from the previously characterized Georgian isolate. A small-scale survey confirmed the presence of CLV-1 in 47 out of 151 sweet cherry samples tested, and partial sequencing of 15 isolates showed a high degree of nucleotide sequence similarity among them.
