Complete Nucleotide Sequence of a Partitivirus from Rhizoctonia solani AG-1 IA Strain C24

Viruses, 2018
The complete genome of a novel double-stranded (ds) RNA mycovirus, named as Rhizoctonia solani partitivirus 5 (RsPV5), isolated from rice sheath blight fungus R. solani AG-1 IA strain C24, was sequenced and analysed. RsPV5 consists of two segments, dsRNA-

The Viromes of Mosquitoes from the Natural Landscapes of Western Siberia

Viruses, 2023
The metagenomic analysis of mosquitoes allows for the genetic characterization of mosquito-associated viruses in different regions of the world. This study applied a metagenomic approach to identify novel viral sequences in seven species of mosquitoes ...

Molecular Characterization of a Novel Putative Partitivirus Infecting Cytospora sacchari, a Plant Pathogenic Fungus

The Plant Pathology Journal, 2014
Three double-stranded RNAs (dsRNAs), approximately 1.85, 1.65 and 1.27 kb in size, were detected in an isolate of Cytospora sacchari from Iran. Partial nucleotide sequence revealed a 1,284 bp segment containing one ORF that potentially encodes a 405 aa ...

Omnipresence of Partitiviruses in Rice Aggregate Sheath Spot Symptom-Associated Fungal Isolates from Paddies in Thailand

Viruses, 2021
Partitiviruses are one of the most prevalent double-stranded RNA viruses that have been identified mostly in filamentous fungi and plants. Partitiviruses generally infect host fungi asymptomatically but infrequently exert significant effect(s) on ...

The ORF2 protein of Fusarium graminearum virus 1 suppresses the transcription of FgDICER2 and FgAGO1 to limit host antiviral defences

Molecular Plant Pathology, Volume 21, Issue 2, Page 230-243, February 2020., 2020
The ORF2 protein of Fusarium graminearum virus 1 can directly repress the induction of FgDICER2 and FgAGO1 at the transcriptional level to counteract the RNAi defence response of Fusarium graminearum. Summary The filamentous fungus Fusarium graminearum possesses an RNA‐interference (RNAi) pathway that acts as a defence response against virus infections

Taxonomic reorganization of family Partitiviridae and other recent progress in partitivirus research

Virus Research, 2014
Phylogenetic analyses have prompted a taxonomic reorganization of family Partitiviridae (encapsidated, bisegmented dsRNA viruses that infect plants, fungi, or protozoa), the focus of this review. After a brief introduction to partitiviruses, the taxonomic changes are discussed, including replacement of former genera Partitivirus, Alphacryptovirus, and ...

Diverse Partitiviruses From the Phytopathogenic Fungus, Rosellinia necatrix

Frontiers in Microbiology, 2020
Partitiviruses (dsRNA viruses, family Partitiviridae) are ubiquitously detected in plants and fungi. Although previous surveys suggested their omnipresence in the white root rot fungus, Rosellinia necatrix, only a few of them have been molecularly and ...

A novel mycovirus associated to Alternaria alternata comprises a distinct lineage in Partitiviridae

Virus Research, 2018
In the present work, we report a novel mycovirus that infects Alternaria alternata. The mycovirus has isometric particles of approximately 30nm and the genome consists of two molecules of dsRNA, dsRNA1 with 1833bp, encoding a putative RNA-dependent RNA polymerase (RdRp) and dsRNA2, with 1680bp in length, encoding the putative capsid protein (CP).

Characterization of a Novel Mycovirus from the Phytopathogenic Fungus Botryosphaeria dothidea

Viruses, 2022
Botryosphaeria dothidea is, globally, one of the most economically important phytopathogenic fungi worldwide, causing the canker and dieback of fruit trees. An increasing number of viruses infecting B. dothidea have lately been reported, several of which
