“…Mycoviruses with single-stranded DNA (ssDNA) genomes have been classified in the family Genomoviridae [ 8 ]. New mycoviruses are constantly reported, and many still remain unclassified [ 6 ] or are classified into newly proposed families, such as Fusariviridae [ 9 , 10 ], Tetramycoviridae [ 11 ], Polymycoviridae [ 12 ], Alternaviridae [ 13 ], and Yadokariviridae [ 14 ].…”

Mycoviruses appear to be widespread in Fusarium species worldwide. The aim of this work was to identify mycoviral infections in Fusarium spp., isolated from maize and sorghum grown in Argentina, and to estimate their potential effects on the pathogenicity and toxigenesis of the host fungus towards maize. Mycoviruses were identified in 2 out of 105 isolates analyzed; Fusarium verticillioides strain Sec505 and Fusarium andiyazi strain 162. They were characterized as members of the genus Mitovirus by high-throughput sequencing and sequence analysis. The F. verticillioides mitovirus was a novel mycovirus whereas the F. andiyazi mitovirus was found to be a new strain of a previously identified mitovirus. We have named these mitoviruses, Fusarium verticillioides mitovirus 1 (FvMV1) and Fusarium andiyazi mitovirus 1 strain 162 (FaMV1-162). To our knowledge, FvMV1 is the first mycovirus reported as naturally infecting F. verticillioides, the major causal agent of ear rot and fumonisin producer in corn. Both mitoviruses exhibited 100% vertical transmission rate to microconidia. The Fa162 strain infected with FaMV1-162 did not show phenotypic alterations. In contract, F. verticillioides Sec505 infected with FvMV1 showed increased virulence as well as microconidia and fumonisin-B1 production, compared with two uninfected strains. These results suggest that FvMV1 could have a role in modulating F. verticillioides pathogenicity and toxin production worth further exploring.

Fungal pathogenic populations such as Sclerotinia, Rhizoctonia and Fusarium are ubiquitous and have broad range of host enabling them to cause a severe infection resulting in huge yield losses. Albeit the various tactics such as cultural, mechanical implemented to counteract the havoc, it still creates a formidable challenge to the researchers to keep the pathogenic population below threshold. From Eco-friendly sustenance perspective, Biological control can play a vital role in combination along with the other efficient tactics. In field condition various strains are available having two characters namely virulent and hypovirulent, the latter may exhibit hypovirulent nature genetically or due to the invasion of mycoviruses becomes hypovirulent. In both the cases are of interest to the researchers in studying the biological control exhibited by the mycoviruses. The biocontrol agents include Mycoviruses, which plays a significant role in infecting the virulent fungal pathogen by reducing their virulence giving to a phenomenon known as Hypovirulence. Their genome consist of mostly dsRNA and others include +ssRNA, -ssRNA and dsDNA. These studies in fungal and viral interaction can lead to the development of novel biological control strategies and help us to explore upto the molecular level.

“…Two members of the newly proposed family Alternaviridae have been isolated from Fusarium , Fusarium graminearum alternavirus 1 (FgAV1) from F. graminearum strain AH11 (He et al, 2018), Fusarium incarnatum alternavirus 1 (FiAV1) from F. incarnatum strain LY003-07 (Zhang et al, 2019). The genome of FgAV1 possesses three dsRNA segments, dsRNA1 (3,524 bp), dsRNA2 (2,470 bp), and dsRNA3 (2,460 bp), each coding an ORF.…”

“…FgAV1 dsRNA1 encodes an RdRp, 126 kDa in size, while dsRNA2 and dsRNA3 encode polypeptides of unknown function, 84 and 81 kDa in size, respectively. The RdRp of FgAV1 is most similar to Fusarium poae alternavirus 1 (FpAV1), with 98% (ORF1), 99% (ORF2), and 98% (ORF3) aa sequence identities (He et al, 2018), while the terminal sequences of FpAV1 have not been determined (Osaki et al, 2016). Compared to the genomic composition (4 dsRNA segments) of three other members of this family, namely, Alternaria alternata virus 1 (AaV1) (Aoki et al, 2009), Aspergillus mycovirus 341 (AMV) (Hammond et al, 2008), and Aspergillus foetidus mycovirus (AfMV) (Kozlakidis et al, 2013), FgAV1/AH11 and FpAV1 both lack the fourth segment.…”

Fusarium is an important genus of plant pathogenic fungi, and is widely distributed in soil and associated with plants worldwide. The diversity of mycoviruses in Fusarium is increasing continuously due to the development and extensive use of state-of-the-art RNA deep sequencing techniques. To date, fully-sequenced mycoviruses have been reported in 13 Fusarium species: Fusarium asiaticum, F. boothii, F. circinatum, F. coeruleum, F. globosum, F. graminearum, F. incarnatum, F. langsethiae, F. oxysporum, F. poae, F. pseudograminearum, F. solani , and F. virguliforme . Most Fusarium mycoviruses establish latent infections, but some mycoviruses such as Fusarium graminearum virus 1 (FgV1), Fusarium graminearum virus-ch9 (FgV-ch9), Fusarium graminearum hypovirus 2 (FgHV2), and Fusarium oxysporum f. sp. dianthi mycovirus 1 (FodV1) cause hypovirulence. Rapid advances in various omics technologies used to elucidate genes or biological processes can facilitate an improved understanding of mycovirus-host interactions. The review aims to illuminate the recent advances in studies of mycoviruses in Fusarium , including those related to diversity, molecular mechanisms of virus-host interaction. We also discuss the induction and suppression of RNA silencing including the role of RNAi components as an antiviral defense response.
