Abstract
A new virus belonging to the genus Vitivirus in the family Betaflexiviridae was identified by next-generation sequencing of a blueberry plant showing green mosaic symptoms. The genome organization of the virus, which is tentatively named “blueberry green mosaic-associated virus” (BGMaV), is typical of vitiviruses, with five open reading frames (ORFs) and a polyadenylated 3’ terminus. The ORFs code for the viral replicase, a 16K protein of unknown function, a movement protein, a coat protein (CP), and a nucleic acid binding protein. Phylogenetic analyses based on the deduced amino acid sequence of the CP and conserved motifs of the RNA-dependent RNA polymerase confirmed the taxonomic placement of BGMaV in the genus Vitivirus.
