Complete genome sequence of a carlavirus identified in grapevine (Vitis sp) in Greece.

Using high-throughput sequencing, we identified a novel carlavirus sequence in a 28-year-old 'Kotsifali' grapevine sample collected in Heraklion (Crete, Greece). Using RT-PCR and 5'/3' RACE together with Sanger sequencing, the complete genome sequence of 8299 nt was confirmed and found to contain five open reading frames (ORFs) but to lack an ORF6, which is present in some members of the genus Carlavirus. The novel sequence is most similar to those of two carlaviruses infecting caper, and taking into account the ICTV nomenclature, we propose the name "grapevine carlavirus 1" for this new virus.
