Abstract


A virus species provisionally named Grapevine virus F (GVF) was found in grapevine by deep sequencing. GVF is a vitivirus distinctly different from the other four members of this genus, as shown by nucleotide sequence and phylogenetic analysis. An RT-PCR test was developed for the detection of this virus. In a collection of 454 grapevine accessions from worldwide sources, an infection rate of 7% was found.
