Hypovirulence-associated mycovirus epidemics cause pathogenicity degeneration of Beauveria bassiana in the field

open access: yesVirology Journal, 2023
Background The entomogenous fungus Beauveria bassiana is used as a biological insecticide worldwide, wild B. bassiana strains with high pathogenicity in the field play an important role in controlling insect pests via not only screening of highly ...

Double-Stranded RNA Mycovirus from Fusarium graminearum [PDF]

open access: yesApplied and Environmental Microbiology, 2002
ABSTRACT Double-stranded RNA (dsRNA) viruses in some fungi are associated with hypovirulence and have been used or proposed as biological control agents. We isolated 7.5-kb dsRNAs from 13 of 286 field strains of Fusarium graminearum isolated from maize in Korea.

Vegetative incompatibility and potential involvement of a mycovirus in the Italian population of Geosmithia morbida [PDF]

open access: yes, 2015
Studies carried out during an Italian outbreak of the Thousand Cankers Disease of walnut, demonstrated that non-coalescing cankers on host plants, separated by equidistant uninfected zones, were associated with incompatible strains of Geosmithia morbida.

Morphological, Pathogenic and Toxigenic Variability in the Rice Sheath Rot Pathogen Sarocladium Oryzae [PDF]

open access: yes, 2020
Sheath rot is an emerging rice disease that leads to considerable yield losses. The main causal agent is the fungus Sarocladium oryzae. This pathogen is known to produce the toxins cerulenin and helvolic acid, but their role in pathogenicity has not been

Patulin Inhibition of Mycovirus Replication in Penicillium stoloniferum [PDF]

open access: yesJournal of General Microbiology, 1976
Penicillium stoloniferum NRRL5267 contains two electrophoretically distinct viruses (PsV-F and PsV-S). An in vivo system was developed to test whether a number of fungal metabolites had antiviral properties on PsV-F replication in O.erties on PsV-F replication in P. stoloniferum.

Molecular Characterization of a Novel Strain of Fusarium graminearum Virus 1 Infecting Fusarium graminearum

open access: yesViruses, 2020
Fungal viruses (mycoviruses) have attracted more attention for their possible hypovirulence (attenuation of fungal virulence) trait, which may be developed as a biocontrol agent of plant pathogenic fungi.

Hypovirulence of Sclerotium rolfsii Caused by Associated RNA Mycovirus [PDF]

open access: yesFrontiers in Microbiology, 2016
Mycoviruses associated with hypovirulence are potential biological control agents and could be useful to study the pathogenesis of fungal host pathogens. Sclerotium rolfsii, a pathogenic fungus, causes southern blight in a wide variety of crops. In this study, we isolated a series of dsRNAs from a debilitated S.

Mechanisms of Primed Defense: Plant Immunity Induced by Endophytic Colonization of a Mycovirus-Induced Hypovirulent Fungal Pathogen

open access: yesMolecular Plant-Microbe Interactions, 2023
How mycovirus-induced hypovirulence in fungi activates plant defense is still poorly understood. The changes in plant fitness and gene expression caused by the inoculation of the fungus Sclerotinia sclerotiorum harboring and made hypovirulent by the ...

Identification and Complete Genome Sequence of an Alternavirus from a Pathogenic Fungus, Fusarium nanum, Collected by Air Sampling

open access: yesPhytoFrontiers, 2023
In this study, fungal spores were collected from the air, and mycelium was grown in Petri dishes containing potato dextrose agar medium in the lab. Based on the morphological and molecular characteristics, the fungus was identified as Fusarium nanum.
