“…Mycoviruses belonging to families with positive-sense single-stranded RNA (+ssRNA) genomes display considerable diversity in terms of genome size, with genomes ranging from approximately 2.0 kb to 17.6 kb [ 172 , 347 ]. The majority of +ssRNA mycoviruses have non-segmented genomes, however, the recently classified family Hadakaviridae consists of members with 10 to 11 genome segments [ 7 ].…”

“…The majority of +ssRNA mycoviruses have non-segmented genomes, however, the recently classified family Hadakaviridae consists of members with 10 to 11 genome segments [ 7 ]. While most mycoviruses replicate within the cytoplasm of their host, members of the Mitoviridae family demonstrate a unique replication pattern, taking place in the mitochondria of its fungal host [ 172 ]. More detail on the diversity of genome length and segmentation among +ssRNA mycovirus families and genera is presented in Table 5 .…”

Mycoviruses (viruses of fungi) are ubiquitous throughout the fungal kingdom and are currently classified into 23 viral families and the genus botybirnavirus by the International Committee on the Taxonomy of Viruses (ICTV). The primary focus of mycoviral research has been on mycoviruses that infect plant pathogenic fungi, due to the ability of some to reduce the virulence of their host and thus act as potential biocontrol against these fungi. However, mycoviruses lack extracellular transmission mechanisms and rely on intercellular transmission through the hyphal anastomosis, which impedes successful transmission between different fungal strains. This review provides a comprehensive overview of mycoviruses, including their origins, host range, taxonomic classification into families, effects on their fungal counterparts, and the techniques employed in their discovery. The application of mycoviruses as biocontrol agents of plant pathogenic fungi is also discussed.

“…With the development of next-generation sequencing, more and more whole genomes of mycoviruses have been sequenced and characterized. To date, only two mycoviruses, FpgMBV1 belonging to the mitovirus and FpgMV1 belonging to the megabirnavirus, have been found in F. pseudograminearum [12,15], with no reports of any viruses belonging to the family "Fusariviridae". According to our results, FpFV1 is the rst fusarivirus described to infect F. pseudograminearum.…”

Fusarium pseudograminearum is a pathogenic fungus causeing crown rot. Only two mycovirus have been reported in F. pseudograminearumthus far. Here, we report a fungal virus (mycovirus), Fusarium pseudograminearum fusarivirus 1 (FpFV1), isolated from the F. pseudograminearum strain ZZ-1. FpFV1 has a single-stranded positive-sense RNA (+ssRNA) genome of 6622 nucleotides containing four open reading frames (ORFs). ORF1 encodes for a large 1,550 amino acids (aa) polypeptide with a conserved RNA-dependent RNA polymerase (RdRp) and two helicase domains. The ORF2, ORF3 and ORF4 have overlapping regions and encode putative proteins of 154 aa, 53aa and 429aa, respectively. All three ORFs have unknown functions. Based on the genomic structure, homology searches, and phylogenetic analysis, FpFV1 could be a new member of the proposed “Fusariviridae”. This is the first report of a fusarivirus that infects F. pseudograminearum.

“…Fusarium pseudograminearum is the major pathogen of FCR disease [9][10]. FCR disease causes severe yield losses in winter wheat, estimated at 10 to 35% annually on average [11][12]. Applying chemical fungicides is the main method to control FCR disease, achieving satisfactory control.…”

“…Biological control, including hypovirulenceassociated mycoviruses application, is a promising alternative [14][15]. To our knowledge, currently, only two mycoviruses (Fusarium pseudograminearum megabirnavirus 1 (FpgMBV1) and Fusarium pseudograminearum mitovirus 1 (FpgMV1) have been discovered in F. pseudograminearum [12,15].…”
