Sclerotinia sclerotiorum is a devastating plant pathogen that attacks numerous economically important broad acre and vegetable crops worldwide. Mycoviruses are widespread viruses infect fungi, including S. sclerotiorum. As there were no previous reports of the presence mycoviruses in this Australia, studies undertaken using RNA_Seq analysis to determine diversity 84 Australian isolates collected from various hosts. After RNA sequences subjected BLASTp NCBI database, 285 contigs representing...
Abstract Mycovirus diversity is generally analyzed from isolates of fungal culture at a single point in time as snapshot. The stability mycovirus composition within the same geographical location over remains unclear. Not knowing how population fluctuates field can be source unpredictability successful application virocontrol. To better understand changes time, we monitored interannual dynamics and abundance mycoviruses infecting Sclerotinia sclerotiorum rapeseed-growing for three years. We...
Mycoviruses are an important component of the virosphere, but our current knowledge their genome organization diversity and evolution remains rudimentary. In this study, mycovirus composition in a hypovirulent strain Sclerotinia sclerotiorum was molecularly characterized. Nine mycoviruses were identified assigned into eight potential families. Of them, six close relatives known mycoviruses, while other three had unique organizations evolutionary positions. A deltaflexivirus with tripartite...
ABSTRACT Hypovirulence-associated mycoviruses have the potential as biocontrol agents for plant fungal disease management, and exploration of interactions between these phytopathogenic fungi can provide opportunities to elucidate underlying mechanisms hypovirulence antiviruses. We previously found that Sclerotinia sclerotiorum endornavirus 3 (SsEV3), belonging genus Betaendornavirus within family Endornaviridae , confers on fungus but remains unclear. In this study, we SsEV3-infected strain...
Recently, an increasing number of ourmia-like viruses have been found in fungi; however, the features these remain unknown. Here, we report a novel virus isolated from Sclerotinia sclerotiorum. This virus, named sclerotiorum 4 (SsOLV4), has genome 2982 nt length with G-pentamer (GGGGG) at 5'-terminus and C-pentamer (CCCCC) 3'-terminus. The SsOLV4 only one large putative open reading frame (ORF) predicted both standard codes mitochondrial encodes RNA-dependent RNA polymerase (RdRp). is...
Early blight, caused by Alternaria solani, is an important disease affecting tomatoes. Biological control offers environmentally friendly approach to controlling pathogens. Herein, we identified a B. amyloliquefaciens strain XJ5 and investigated its biocontrol mechanism against A. solani. solani growth was significantly inhibited XJ5, with the inhibition rate of cell-free culture supernatants reaching 82.3%. Furthermore, crude protein extracts conidia germination altered mycelial morphology...
RNA viruses usually have linear genomes and are encapsidated by their own capsids. Here, we newly identified four mycoviruses two previously reported (a fungal reovirus a botybirnavirus) in the hypovirulent strain SCH941 of Sclerotinia sclerotiorum. One discovered mycoviruses, sclerotiorum yadokarivirus 1 (SsYkV1), with nonsegmented positive-sense single-stranded (+ssRNA) genome, was molecularly characterized. SsYkV1 is 5,256 nucleotides (nt) length, excluding poly(A) structure, has large...
Infection by diverse mycoviruses is a common phenomenon in Sclerotinia sclerotiorum. In this study, the full genome of single-stranded RNA mycovirus, tentatively named Hubei sclerotinia virus 1 (HuSRV1), was determined hypovirulent strain 277 S. The HuSRV1 4492 nucleotides (nt) long and lacks poly (A) tail at 3ˊ- terminus. Sequence analyses showed that contains four putative open reading frames (ORFs). ORF1a presumed to encode protein with conserved protease domain transmembrane domain. This...
Mycoviruses have been found in various fungal species across different taxonomic groups, while no viruses reported yet the fungus Exserohilum rostratum. In this study, a novel orfanplasmovirus, namely rostratum orfanplasmovirus 1 (ErOrfV1), was identified strain JZ1 from maize leaf. The complete genome of ErOrfV1 consists two positive single-stranded RNA segments, encoding an RNA-dependent polymerase and hypothetical protein with unknown function, respectively. Phylogenetic analysis revealed...
