Origin, Adaptation and Evolutionary Pathways of Fungal Viruses
Virus Genes 16:1, 119±131, 1998 # 1998 Kluwer Academic Publishers, Boston. Manufactured in The Netherlands. Origin, Adaptation and Evolutionary Pathways of Fungal Viruses SAID A. GHABRIAL Department of Plant Pathology, University of Kentucky, Lexington, KY, USA Abstract. Fungal viruses or mycoviruses are widespread in fungi and are believed to be of ancient origin. They have evolved in concert with their hosts and are usually associated with symptomless infections. Mycoviruses are transmitted intracellularly during cell division, sporogenesis and cell fusion, and they lack an extracellular phase to their life cycles. Their natural host ranges are limited to individuals within the same or closely related vegetative compatibility groups. Typically, fungal viruses are isometric particles 25±50 nm in diameter, and possess dsRNA genomes. The best characterized of these belong to the family Totiviridae whose members have simple undivided dsRNA genomes comprised of a coat protein (CP) gene and an RNA dependent RNA polymerase (RDRP) gene. A recently characterized totivirus infecting a ®lamentous fungus was found to be more closely related to protozoan totiviruses than to yeast totiviruses suggesting these viruses existed prior to the divergence of fungi and protozoa. Although the dsRNA viruses at large are polyphyletic, based on RDRP sequence comparisons, the totiviruses are monophyletic. The theory of a cellular self-replicating mRNA as the origin of totiviruses is attractive because of their apparent ancient origin, the close relationships among their RDRPs, genome simplicity and the ability to use host proteins ef®ciently. Mycoviruses with bipartite genomes ( partitiviruses), like the totiviruses, have simple genomes, but the CP and RDRP genes are on separate dsRNA segments. -

Shedding Light on Mushroom Viruses
CELU Shedding light on mushroom viruses A complex of novel viruses was discovered in commercial mushrooms in the early 2000s, which reduced the quality of this premium horticultural product across Europe. TEAGASC - and EU-funded research has now characterised the viruses and shown that the Agaricus bisporus mushroom is a model system to study fungal viromes. Mushroom virus disease them contained an RNA-dependent RNA polymerase (RdRp) domain, Mushrooms are a high-value export crop, with an annual production characteristic of fungal viruses, and we propose that these represent 18 value in Ireland in the region of €130 million. They can suffer from distinct viruses ( Figure 2 ). A nomenclature is proposed of Agaricus economically damaging viral diseases such as La France disease, which bisporus Virus N (N replaced by a sequential number). Sixteen of the emerged in the 1960s, and which has largely disappeared from modern viruses had a monopartite structure of a single RNA molecule while two farms due to increased hygiene levels. It was a big surprise therefore viruses were segmented viruses: AbV6 consisted of two separate contigs, when virus-like symptoms started to recur in the late 1990s and 2000s, while AbV16 contained four separate contigs. AbV16 is the fungal virus but mushrooms were negative for the 35 nanometre virus particles associated with the brown mushroom symptoms seen in crops affected associated with La France disease. The term Mushroom Virus X (MVX) by MVX. The RdRps of the 18 viruses have closest amino acid homology disease was coined to cover a range of symptoms, which included to a diverse array of positive sense single-stranded RNA viral widespread brown discolouration of what should be pristine white orders/families/genera (ss(+)RNA): Hypoviridae , Tymovirales mushrooms, rendering them unmarketable ( Figure 1 ). -

Three Ourmia-Like Viruses and Their Associated Rnas in Pyricularia
Virology 534 (2019) 25–35 Contents lists available at ScienceDirect Virology journal homepage: www.elsevier.com/locate/virology Three ourmia-like viruses and their associated RNAs in Pyricularia oryzae T Shuhei Ohkitaa,1, Yui Leea,1, Quyet Nguyena, Kenichi Ikedaa, Nobuhiro Suzukib, ∗ Hitoshi Nakayashikia, a Laboratory of Cell Function and Structure, Graduate School of Agricultural Science, Kobe University, Nada Kobe, 657-8501, Japan b Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University, Kurashiki, Okayama, 710-0046, Japan ARTICLE INFO ABSTRACT Keywords: Three ourmia-like viruses, designated Pyricularia oryzae ourmia-like virus (PoOLV) 1 to 3, were identified in a Ourmia-like virus wheat-infecting isolate of P. oryzae. The sizes of the full-length PoOLV1-3 genomes were determined to be 2,528, Subviral RNA 1,671, and 2,557 nt. Interestingly, we also found two abundant single-stranded RNAs sharing their 5’ terminal 25 Mycovirus and 255 nt with PoOLV1 RNA and PoOLV3 RNA, respectively. The PoOLV1- and PoOLV3-associated RNAs (ARNA1 and ARNA3) were 639 and 514 nt in length, and possessed one and two small ORFs, respectively. In the field isolates of P. oryzae, PoOLVs and ARNAs were detectable at varying levels, and the levels of PoOLV1 and ARNA1 as well as those of PoOLV3 and ARNA3, were tightly correlated. In addition, gene silencing of PoOLV1 and PoOLV3 resulted in a reduction of ARNA1 and ARNA3, respectively. There results indicated that replication of ARNA1 and ARNA3 was associated with PoOLV1 and PoOLV3, respectively. 1. Introduction (Solorzano et al., 2000). In contrast, members of Mitovirus, the other genus in Narnaviridae, are thought to replicate in mitochondria since Ourmiavirus is a genus of plant viruses infecting melon, cherry, and they often use mitochondrial genetic code (Hong et al., 1998; Polashock cassava (Lisa et al., 1988; Turina et al., 2017). -
Armillaria Root Rot Fungi Host Single-Stranded RNA Viruses
www.nature.com/scientificreports OPEN Armillaria root rot fungi host single‑stranded RNA viruses Riikka Linnakoski1,5, Suvi Sutela1,5, Martin P. A. Coetzee2, Tuan A. Duong2, Igor N. Pavlov3,4, Yulia A. Litovka3,4, Jarkko Hantula1, Brenda D. Wingfeld2 & Eeva J. Vainio1* Species of Armillaria are distributed globally and include some of the most important pathogens of forest and ornamental trees. Some of them form large long‑living clones that are considered as one of the largest organisms on earth and are capable of long‑range spore‑mediated transfer as well as vegetative spread by drought‑resistant hyphal cords called rhizomorphs. However, the virus community infecting these species has remained unknown. In this study we used dsRNA screening and high‑throughput sequencing to search for possible virus infections in a collection of Armillaria isolates representing three diferent species: Armillaria mellea from South Africa, A. borealis from Finland and Russia (Siberia) and A. cepistipes from Finland. Our analysis revealed the presence of both negative‑ sense RNA viruses and positive‑sense RNA viruses, while no dsRNA viruses were detected. The viruses included putative new members of virus families Mymonaviridae, Botourmiaviridae and Virgaviridae and members of a recently discovered virus group tentatively named “ambiviruses” with ambisense bicistronic genomic organization. We demonstrated that Armillaria isolates can be cured of viruses by thermal treatment, which enables the examination of virus efects on host growth and phenotype using isogenic virus‑infected and virus‑free strains. Te fungal genus Armillaria (Fr.) Staude includes more than 40 described species1. Tey are mainly known as notorious plant pathogens of managed natural forests and plantations of non-native tree species that infect hundreds of diferent plants, including economically important conifers (e.g. -
