Efficient elimination of RNA mycoviruses in aspergillus species using RdRp-inhibitors ribavirin and 2’-C-methylribonucleoside derivatives

Frontiers in Microbiology, 2022
RNA viruses in fungi (mycoviruses) are model systems for understanding the relationships between eukaryotic microorganisms and RNA viruses. To reveal the effects of mycoviruses on host fungi, it is essential to compare the phenotypes between isogenic ...

Geometagenomics illuminates the impact of agriculture on the distribution and prevalence of plant viruses at the ecosystem scale [PDF]

, 2018
Disease emergence events regularly result from human activities such as agriculture, which frequently brings large populations of genetically uniform hosts into contact with potential pathogens.

Characterization of the RNA Mycovirus Infecting Allomyces arbuscula

Journal of General Virology, 1977
Summary The mycovirus infecting Allomyces arbuscula has been fractionated into two particle classes designated A and B. Particles A have a buoyant density of 1.385 g/cm3, in CsCl, a sedimentation coefficient of 75S and contain one major and two minor polypeptides with molecular weights of 34000, 31000 and 28000, respectively.

Bunyaviruses Affect Growth, Sporulation, and Elicitin Production in Phytophthora cactorum

Viruses, 2022
Phytophthora cactorum is an important oomycetous plant pathogen with numerous host plant species, including garden strawberry (Fragaria × ananassa) and silver birch (Betula pendula). P. cactorum also hosts mycoviruses, but their phenotypic effects on the

Tolerance Against Co‐Infection of Two Partitiviruses and Ourmia‐Likevirus Is Common Among Heterobasidion annosum Strains on Artificial Media and in Dead Wood

Forest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Some mycoviruses cause hypovirulence in fungi, but the effects often vary among different host strains. Heterobasidion partitiviruses 13‐an1 and 15‐pa1 (HetPV13‐an1 and HetPV15‐pa1) have been associated with strain‐specific and variable hypovirulence of Heterobasidion annosum, but variation in phenotypic effects of HetPV15‐pa1 or the ...

Characterization of the mycovirus Aspergillus sulphureus partitivirus 1

Archives of Virology
Abstract Fungi are frequently infected with viruses called mycoviruses. Some mycoviruses have shown potential as biocontrol agents because they can weaken the virulence of fungal plant pathogens. Intensive research has been conducted on the diversity of viruses infecting plant pathogens and the functions of such viruses.

Adenine-rich RNA in the Mycovirus of Allomyces arbuscula

Journal of General Virology, 1977
Summary An adenine-rich fraction has been extracted from the mycovirus infecting the Phycomycete Allomyces arbuscula. This fraction which accounts for approximately 8% of the total RNA is heterogeneous and contains tracts of 25 to 45 nucleotides in length. The majority of the poly(A) tracts have a mol. wt. of 1.2 × 104 and a sedimentation value of 2 to

Mikovirus, Pengembangannya sebagai Agens Pengendali Hayati [PDF]

, 2017
Mycoviruses are viruses that infect fungus. In plant pathogenic fungi, mycoviruses infection may cause hypovirulence. Therefore, mycoviruses could be developed as biological control agents against the plant pathogenic fungi. Abroad, mycoviruses have long

First Report of Cryphonectria carpinicola in Croatia

Forest Pathology, Volume 55, Issue 2, April 2025.
ABSTRACT Cryphonectria carpinicola, the most recently described species in the genus Cryphonectria, is gaining research interest due to its involvement in common hornbeam (Carpinus betulus) decline. So far, no symptoms of hornbeam decline have been observed in Croatian forests. However, following a chance observation of a Cryphonectria‐like stromata on
