“…According to some taxonomist accounts, 30% of mycoviruses have positive-sense single-stranded RNA (+ssRNA) genomes, while the majority of mycoviruses have double-stranded RNA (dsRNA) genomes [18][19][20]. A Gemini group virus associated with mycoviruses has been newly informed [7,21,22].…”

All key families of plant-infecting fungi have been observed to be infected by mycoviruses, which are substantial and ubiquitous viruses. Mycoviruses, like all other plant and animal viruses, must reproduce in live cells. These viruses spread either during spore production or cell division. Few mycoviruses are known to have a positive single-stranded RNA genome, while the majority have double-stranded RNA genomes. Few mycoviruses have been identified as the causative agents of triggering atypical pigmentation and sporadic growth to alter the sexual reproduction of the host. These viruses are categorized into taxonomic groups as developed from plant viruses. mycoviruses are notable due to their amazing capacity to cause a dramatic decrease in the virulence (hypovirulence) of the host. It has been observed that mycoviruses do not necessarily cause hypovirulence, but they also impart hypervirulence to the host fungi. The current effort summarizes the data regarding mycoviral diversity, taxonomy and their role in the pathogenesis of pathogenic fungi.

“…For example, the tobacco mosaic virus (TMV) causes poor growth in tobacco plants, while norovirus is known to cause diarrhea in mammals [ 8 , 9 ]. In the field of fungal research, viral infections have significantly reduced the yield of edible fungi, thereby attracting increasing attention to fungal diseases caused by viruses [ 10 ]. However, due to their apparent relevance to health [ 11 ], fungal-associated viruses have been understudied compared to viruses affecting humans, animals, or plants.…”

Background Like all other species, fungi are susceptible to infection by viruses. The diversity of fungal viruses has been rapidly expanding in recent years due to the availability of advanced sequencing technologies. However, compared to other virome studies, the research on fungi-associated viruses remains limited. Results In this study, we downloaded and analyzed over 200 public datasets from approximately 40 different Bioprojects to explore potential fungal-associated viral dark matter. A total of 12 novel viral sequences were identified, all of which are RNA viruses, with lengths ranging from 1,769 to 9,516 nucleotides. The amino acid sequence identity of all these viruses with any known virus is below 70%. Through phylogenetic analysis, these RNA viruses were classified into different orders or families, such as Mitoviridae, Benyviridae, Botourmiaviridae, Deltaflexiviridae, Mymonaviridae, Bunyavirales, and Partitiviridae. It is possible that these sequences represent new taxa at the level of family, genus, or species. Furthermore, a co-evolution analysis indicated that the evolutionary history of these viruses within their groups is largely driven by cross-species transmission events. Conclusions These findings are of significant importance for understanding the diversity, evolution, and relationships between genome structure and function of fungal viruses. However, further investigation is needed to study their interactions.

“…Mycoviruses are widespread in all major taxa of fungi, including yeasts and mushrooms, as well as plant-, insect-, and human-pathogenic fungi, and other organisms such as oomycetes [1][2][3]. According to the latest taxonomy report of the International Committee on Virus Taxonomy (ICTV) and the accepted list of all mycoviruses in the ICTV VMR_MSL38_v2 (https://ictv.global/vmr, (accessed on 17 January 2024), there are 30 families and two genera containing a total of 491 species that infect fungi.…”

A novel strain of Fusarium oxysporum virus 1 (FoV1) was identified from the Fusarium oxysporum f. sp. niveum strain X-GS16 and designated as Fusarium oxysporum virus 1-FON (FoV1-FON). The full genome of FoV1-FON is 2902 bp in length and contains two non-overlapping open reading frames (ORFs), ORF1 and ORF2, encoding a protein with an unknown function (containing a typical −1 slippery motif G_GAU_UUU at the 3′-end) and a putative RNA-dependent RNA polymerase (RdRp), respectively. BLASTx search against the National Center for the Biotechnology Information (NCBI) non-redundant database showed that FoV1-FON had the highest identity (97.46%) with FoV1. Phylogenetic analysis further confirmed that FoV1-FON clustered with FoV1 in the proposed genus Unirnavirus. FoV1-FON could vertically transmit via spores. Moreover, FoV1-FON was transmitted horizontally from the F. oxysporum f. sp. niveum strain X-GS16 to the F. oxysporum strain HB-TS-YT-1hyg. This resulted in the acquisition of the F. oxysporum strain HB-TS-YT-1hyg-V carrying FoV1-FON. No significant differences were observed in the sporulation and dry weight of mycelial biomass between HB-TS-YT-1hyg and HB-TS-YT-1hyg-V. FoV1-FON infection significantly increased the mycelial growth of HB-TS-YT-1hyg, but decreased its virulence to potato tubers and sensitivity to difenoconazole, prochloraz, and pydiflumetofen. To our knowledge, this is the first report of hypovirulence and reduced sensitivity to difenoconazole, prochloraz, and pydiflumetofen in F. oxysporum due to FoV1-FON infection.
