“…By 1906, the virus had destroyed thousands of acres of sugarcane (Hughes and Robinson, 1961). Now, FDV is known to cause this serious disease of sugarcane in Southeast Asian and Pacific countries, including New Guinea, Fiji, Australia, Madagascar, Vanuatu, the Philippines, and Samoa (Harding et al, 2006;Magarey et al, 2019). Its only known naturally infected host is sugarcane (S. officinarum L.), but other Saccharum species, Sorghum species, and maize can be experimentally inoculated with viruliferous planthoppers (Hughes and Robinson, 1961;.…”

“…Plant-infecting fijiviruses have double-shelled, icosahedral particles approximately 70 nm in diameter, with spherical, short surface spikes (A spikes) on each of the 12 vertices of the icosahedron (Harding et al, 2006;Attoui et al, 2012). The outer shell is very fragile, leaving the inner shell with 12 B spikes (Teakle and Steindl, 1969;Hatta and Francki, 1977).…”

Viruses in genus Fijivirus (family Reoviridae) have caused serious damage to rice, maize and sugarcane in American, Asian, European and Oceanian countries, where seven plant-infecting and two insect-specific viruses have been reported. Because the planthopper vectors are the only means of virus spread in nature, their migration and efficient transmission of these viruses among different crops or gramineous weeds in a persistent propagative manner are obligatory for virus epidemics. Understanding the mechanisms of virus transmission by these insect vectors is thus key for managing the spread of virus. This review describes current understandings of main fijiviruses and their insect vectors, transmission characteristics, effects of viruses on the behavior and physiology of vector insects, molecular transmission mechanisms. The relationships among transmission, virus epidemics and management are also discussed. To better understand fijivirus-plant disease system, research needs to focus on the complex interactions among the virus, insect vector, insect microbes, and plants.

Southern rice black-streaked dwarf virus (SRBSDV) is a novel Fijivirus prevalent in rice in southern and central China, and northern Vietnam. Its genome has 10 segments of double-stranded RNA named S1 to S10 according to their size. An isolate of SRBSDV, JNi4, was obtained from naturally infected maize plants from Ji'ning, Shandong province, in the 2008 maize season. Segments S7 to S10 of JNi4 share nucleotide identities of 72.6%-73.1%, 72.3%-73%, 73.9%-74.5% and 77.3%-79%, respectively, with corresponding segments of Rice black-streaked dwarf virus isolates, and identities of 99.7%, 99.1%-99.7%, 98.9%-99.5%, and 98.6%-99.2% with those of SRBSDV isolates HN and GD. JNi4 forms a separate branch with GD and HN in the phylogenetic trees constructed with genomic sequences of S7 to S10. These results confirm the proposed taxonomic status of SRBSDV as a distinct species of the genus Fijivirus and indicate that JNi4 is an isolate of SRBSDV. Shandong is so far the northernmost region where SRBSDV is found in China.

“…Reoviruses are currently classified as species belonging to 15 different genera, including a broad diversity of arthropod-borne viruses, which include the plant reoviruses that are classified within the genera Phytoreovirus, Fijivirus and Oryzavirus, and the vertebrate reoviruses that are classified within the genera Coltivirus, Orbivirus and Seadornavirus. Among the plant-infecting reoviruses, insect-transmitted fijiviruses are the most common viral pathogens of a variety of gramineous plants worldwide, including Fiji disease virus (FDV) [15], garlic dwarf virus (GDV) [16], maize rough dwarf virus (MRDV) [17], Mal de Rio Cuarto virus (MRCV) [18], oat sterile dwarf virus (OSDV) [19], pangola stunt virus (PaSV) [20], rice black streaked dwarf virus (RBSDV) [21] and southern rice black-streaked dwarf virus (SRBSDV) [22]. In addition, Nilaparvata lugens reovirus (NLRV; genus Fijivirus), an insect-specific fijivirus isolated from the brown planthopper Nilaparvata lugens, was also recognized by the International Committee on Taxonomy of Viruses (ICTV) [23].…”

Discovery and characterization of a novel insect-specific reovirus isolated from Psammotettix alienus

A novel double-stranded RNA (dsRNA) virus designated Psammotettix alienus reovirus (PARV) was found in the leafhopper Psammotettix alienus in China. Spherical particles approximately 70 nm in diameter arranged in a crystalline array were observed in the salivary gland tissues of infected leafhoppers by transmission electron microscopy. Some viral particles were also encased in tubules, similar to those of previously described reoviruses. Whole-genome sequencing revealed that the dsRNA genome of PARV consists of 29 569 nucleotides (nt) divided into 10 segments ranging from 4403 to 1476 nt, with low G+C content (29.5–36.5 %). All segments contained conserved terminal sequences (5′AAC…GUCA3′) and specific panhandle structures formed by inverted terminal repeats in the noncoding regions. Phylogenetic analysis based on the deduced RNA-dependent RNA polymerase (RdRp) revealed that PARV was in the fijivirus clade, but in a monophyletic lineage with an unassigned insect reovirus (Hubei insect virus 2, HBIV-2), although PARV and HBIV-2 are distinct enough to represent a new group within the genus Fijivirus. Biological assays showed that PARV infects P. alienus but not wheat plants, implying that it is a new insect-specific reovirus in the leafhopper. Given these features, PARV should be considered as a new species in the genus Fijivirus, family Reoviridae.
