“…The rate of mycovirus discovery was accelerated by next-generation sequencing (NGS), which allows a comprehensive analysis of fungal meta-transcriptomes and virus-derived small RNA (vsiRNA) populations. Application of these methods revealed the existence of multiple mycoviruses that could be grouped into Mononegavirales, Bunyaviridae, Aspiviridae, Ourmiavirus, Virgaviridae, Tymoviridae, Tombusviridae, Barnaviridae, Benyviridae, Chrysoviridae, Megabirnaviridae, Quadriviridae, Mymonaviridae, Endornaviridae, Gammaflexiviridae, Genomoviridae, Hypoviridae, Narnaviridae, Partitiviridae, or Totiviridae virus families, although many novel mycoviruses cannot be classified (Vainio et al, 2015;Marzano et al, 2016;Nerva et al, 2016;Donaire and Ayllon, 2017;Mu et al, 2017;Zhu et al, 2018;Velasco et al, 2019). Virome sequencing can be used to characterize potential mycoviruses for bio-control of fungal diseases in plants.…”

Frontiers in Microbiology | www.frontiersin.org February 2020 | Volume 11 | Article 240 Yao et al. Virome Identification and Characterization of Fusarium spp.was observed and the characterization of the four-segment dsRNA chrysovirus was performed with aid of electron microscopy and analysis of the encapsidated RNAs. These findings provide insight into the diversity and spectrum of mycoviruses in PBD pathogens and should be useful for exploring agents to control the disease.

“…Some of the viruses reported to infect R. solani belong to well-studied mycovirus families, such as Barnaviridae, Botourmiaviridae, Deltaflexiviridae, Endornaviridae, Hypoviridae, Megabirnaviridae, Narnaviridae, and Partitiviridae (Tables 2 and S1). Others belong or are closely related to families traditionally known to infect plants, such as CMV [7] and proposed members of the orders Bunyavirales, Serpentovirales, and Tymovirales [6,[27][28][29]. In general, recent large-scale metatranscriptomic analyses of plant pathogenic fungi has led to the discovery of several (−)ssRNA mycoviruses including mymonaviruses [19,[30][31][32] and other mycoviruses related to the bi-and tri-segmented peribunyaviruses and phenuiviruses, and the multi-segmented ophioviruses [19,33,34].…”

“…The ORFs in the largest segment encode a putative RdRp and a capsid protein (CP), whereas the ORFs in the smallest segment encode two proteins of unknown function [53,54]. Other unclassified members of the family include Sclerotinia sclerotiorum megabirnavirus 1 (SsMBV1) [55], Rosellinia necatrix megabirnavirus 2 (RnMBV2) [56], Pleospora megabirnavirus 1 (PMBV1) [57], and Entoleuca megabirnavirus 1 (EnMBV1) [27]. Virus transmission occurs either horizontally through anastomosis or vertically via sporulation [53].…”

“…For instance, Lentinula edodes negative-strand RNA virus 2 (LeNSRV2) infecting Lentinula edodes is a phenui-like virus and the first segmented (−)ssRNA virus found to infect fungi [28], while more viruses related to the order Bunyavirales were reported in fungi associated with the marine organism Holothuria polii [29] and the ascomycete Entoleuca sp. [27]. Recently, two viruses infecting R. solani and related to bunyaviruses were reported: Rhizoctonia solani bunya/phlebo-like virus 1 (RsBPLV1; Table 2) [6] and Rhizoctonia solani negative-stranded virus 4 (RsNSV4 ; Table S1).…”

The cosmopolitan fungus Rhizoctonia solani has a wide host range and is the causal agent of numerous crop diseases, leading to significant economic losses. To date, no cultivars showing complete resistance to R. solani have been identified and it is imperative to develop a strategy to control the spread of the disease. Fungal viruses, or mycoviruses, are widespread in all major groups of fungi and next-generation sequencing (NGS) is currently the most efficient approach for their identification. An increasing number of novel mycoviruses are being reported, including double-stranded (ds) RNA, circular single-stranded (ss) DNA, negative sense (−)ssRNA, and positive sense (+)ssRNA viruses. The majority of mycovirus infections are cryptic with no obvious symptoms on the hosts; however, some mycoviruses may alter fungal host pathogenicity resulting in hypervirulence or hypovirulence and are therefore potential biological control agents that could be used to combat fungal diseases. R. solani harbors a range of dsRNA and ssRNA viruses, either belonging to established families, such as Endornaviridae, Tymoviridae, Partitiviridae, and Narnaviridae, or unclassified, and some of them have been associated with hypervirulence or hypovirulence. Here we discuss in depth the molecular features of known viruses infecting R. solani and their potential as biological control agents.

The newly established virus family Phenuiviridae in Bunyavirales harbors viruses infecting three kingdoms of host organisms (animals, plants, and fungi), which is rare in known virus families. Many phenuiviruses are arboviruses and replicate in two distinct hosts (e.g., insects and humans or rice). Multiple phenuiviruses, such as Dabie bandavirus, Rift Valley fever phlebovirus, and Rice stripe tenuivirus, are highly pathogenic to humans, animals, or plants.They impose heavy global burdens on human health, livestock industry, and agriculture and are research hotspots. In recent years the taxonomy of Phenuiviridae has been expanded greatly, and researches on phenuiviruses have made significant progress. With these advances, this review drew a novel panorama regarding the biomedical significance, distribution, morphology, genomics, taxonomy, evolution, replication, transmission, pathogenesis, and control of phenuiviruses, to aid researchers in various fields to recognize this highly adaptive and very important virus family.
