We determined the complete genome sequence of a highly divergent South Korean (SK) isolate of a cherry-associated luteovirus (ChALV) from peach. The ChALV-SK genome consists of 5,815 nucleotides, and contains five open reading frames (ORFs). A comparative analysis of the full genome showed only 73.1% nucleotide sequence identity with a recently described ChALV from the Czech Republic (CZ). Amino acid similarities of the individual ORFs between ChALV-SK and other luteoviruses range from 17.3 to 92%, which places the new isolate close to the species demarcation value for luteoviruses. Results show our ChALV-SK isolate to be highly diverged from the ChALV-CZ isolate.

Two novel viruses, isolated in Bonghwa, Republic of Korea, from an Ixeridium dentatum plant with yellowing mottle symptoms, have been provisionally named Ixeridium yellow mottle-associated virus 1 (IxYMaV-1) and Ixeridium yellow mottle-associated virus 2 (IxYMaV-2). IxYMaV-1 has a genome of 6,017 nucleotides sharing a 56.4% sequence identity with that of cucurbit aphid-borne yellows virus (genus Polerovirus). The IxYMaV-2 genome of 4,196 nucleotides has a sequence identity of less than 48.3% with e other species classified within the genus Umbravirus. Genome properties and phylogenetic analysis suggested that IxYMaV-1 and -2 are representative isolates of new species classifiable within the genus Polerovirus and Umbravirus, respectively.

An evaluation of the virus population in rice plants using next-generation sequencing technologies resulted in the discovery of a new RNA virus, tentatively named rice virus A (RVA). The complete RVA genome sequence was determined and analyzed, revealing a genome organization resembling that of viruses classified in the genera Aureusvirus, Tombusvirus and Zeavirus within the family Tombusviridae. With 4,832 nucleotides, the RVA genome may be the largest monopartite genome sequenced to date in the family Tombusviridae. The 453-amino acid RVA coat protein shares the highest identity with the gp3 protein of an unclassified carascovirus, SF1 (GenBank accession no. KF510027) isolated from San Francisco wastewater, rather than the coat protein of any known member of the family Tombusviridae. These novel characteristics represent a significant divergence from the genomes of viruses belonging to the sixteen existing genera of the family Tombusviridae, demonstrating that RVA is likely a new family member.

A virus isolate designated Angelica bushy stunt virus (AnBSV), provisionally representing a new species in the genus Caulimovirus, was discovered in the medicinal plant Angelica dahurica. The complete 8,300-nt genomic DNA of AnBSV had seven putative open reading frames containing conserved domains/motifs, which are typical features of caulimoviruses, and showed the greatest nucleotide sequence identity (74% identity and 27% query coverage) to a lamium leaf distortion virus isolate. Interestingly, the new caulimovirus exists as endogenous pararetroviral sequences in the host plant and is considered to have multiple defective plant genome-integrated copies that may lead to the generation of subgenomic DNA species.

ABSTRACT Habenaria mosaic virus (HaMV), a member of the genus Potyvirus in the family Potyviridae, was first discovered from Habenaria radiata in Japan. The complete genomic sequence of a South Korean isolate (PA1) of HaMV infecting Plantago asiatica L. was determined with high-throughput RNA sequencing.
