“…Based on phylogenetic analyses of the conserved polymerase, helicase, and methyltransferase motifs (Koonin et al, 1993), RBDV belongs to the ancestral lineage of the family Bromoviridae (Isogai et al, 2019). The genome size of BraRV1 is similar to that of viruses in Bromoviridae (8.0 kb) and RBDV (7.7 kb), but differs from those of Bromoviridae viruses that have the three-segmented genome.…”

Viral RNA Genomes Identified from Marine Macroalgae and a Diatom

Protists provide insights into the diversity and function of RNA viruses in marine systems. Among them, marine macroalgae are good targets for RNA virome analyses because they have a sufficient biomass in nature. However, RNA viruses in macroalgae have not yet been examined in detail, and only partial genome sequences have been reported for the majority of RNA viruses. Therefore, to obtain further insights into the distribution and diversity of RNA viruses associated with marine protists, we herein examined RNA viruses in macroalgae and a diatom. We report the putative complete genome sequences of six novel RNA viruses from two marine macroalgae and one diatom holobiont. Four viruses were not classified into established viral genera or families. Furthermore, a virus classified into Totiviridae showed a genome structure that has not yet been reported in this family. These results suggest that a number of distinct RNA viruses are widespread in a broad range of protists.

“…There is a lack of information currently available on the topology and aetiology of Idaeovirus MPs in general and RBDV in particular. However, groups of researchers consider them to be related to the Bromoviridae family (particularly to alfalfa mosaic virus and tobacco string virus) [63][64][65][66][67]. The alfamovirus MP is known to be associated with plasmodesmata and accomplishes intracellular movement by increasing their size exclusion limit and forming tubuli [68,69].…”

Raspberry bushy dwarf virus (RBDV) is an economically significant pathogen of raspberry and grapevine, and it has also been found in cherry. Most of the currently available RBDV sequences are from European raspberry isolates. This study aimed to sequence genomic RNA2 of both cultivated and wild raspberry in Kazakhstan and compare them to investigate their genetic diversity and phylogenetic relationships, as well as to predict their protein structure. Phylogenetic and population diversity analyses were performed on all available RBDV RNA2, MP and CP sequences. Nine of the isolates investigated in this study formed a new, well-supported clade, while the wild isolates clustered with the European isolates. Predicted protein structure analysis revealed two regions that differed between α- and β-structures among the isolates. For the first time, the genetic composition of Kazakhstani raspberry viruses has been characterized.

“…Among their members is the representative idaeovirus, raspberry bushy dwarf virus (RBDV), reported from Japan (Isogai et al 2012). RBDV has a bi-partite genome (Natsuaki et al 1991), and RNA1 encodes an RNA silencing suppressor, which is also involved in efficient lateral transmission through pollen (Isogai et al 2019(Isogai et al , 2020.…”

An increasing number of plant viruses and viroids have been reported from all over the world due largely to metavirogenomics approaches with technological innovation. Herein, the official changes of virus taxonomy, including the establishment of megataxonomy and amendments of the codes of virus classification and nomenclature, recently made by the International Committee on Taxonomy of Viruses were summarized. The continued efforts of the plant virology community of Japan to index all plant viruses and viroids occurring in Japan, which represent 407 viruses, including 303 virus species and 104 unclassified viruses, and 25 viroids, including 20 species and 5 unclassified viroids, as of October 2021, were also introduced. These viruses and viroids are collectively classified into 81 genera within 26 families of 3 kingdoms (Shotokuvirae, Orthornavirae, Pararnavirae) across 2 realms (Monodnaviria and Riboviria). This review also overviewed how Japan’s plant virus/viroid studies have contributed to advance virus/viroid taxonomy.
