Complete genome sequence of a new virus from Allium sativum L in China

AbstractThe complete genome of a new virus belonging to the familyBetaflexiviridae was identified in garlic and sequenced by next-generation sequencing and reverse transcription PCR. The complete RNA genome (GenBank accession number OP021693) is 8191 nucleotides in length, excluding the 3 ’ poly(A) tail, and contains five open reading frames (ORFs). These open reading frames encode the viral replicase, triple gene block, and coat protein, and the genome organization is typical of members of the subfamilyQuinvirinae. The virus has been tentatively named"garlic yellow curl virus" (GYCV). Phylogenetic analysis suggested that it represents an independent evolutionary lineage in the subfamily, clustering with the currently unclassified garlic yellow mosaic associated virus (GYMaV) and peony betaflexivirus 1 (PeV1). Differences between the phylogenies inferred for the replicase and coat protein indicate that the new virus does not belong to any established genus of the familyBetaflexiviridae. This is the first report of GYCV in China.
