Abstract

Complete genomic sequences of garlic viruses A (Gar V-A) and C (Gar V-C), members of an unassigned virus group recently identified in garlic plants, were determined. Their respective genomes consist of 8 660 and 8 405 nucleotides. The genomic structure and organization of these viruses are similar to shallot virus X (ShVX) which is the type species of the newly ratified genus Allexivirus . Phylogenetic analysis based on the amino acid sequences of the putative proteins including RNA-dependent RNA polymerase (RdRP), DNA helicase, or viral coat protein showed that the GarV-type viruses should be included in the genus Allexivirus . Furthermore, the amino acid sequence in the RdRP hypervariable region is highly divergent among the viruses in the genus Allexivirus , suggesting that they evolved independently from a hypothetical ancestor virus(es).
