Hypovirulence of Didymella bryoniae Associated with dsRNA
Journal of Phytopathology, 2004Abstract Didymella bryoniae, isolate 98–18, recovered from watermelon seedlings with symptoms of gummy stem blight, showed abnormal growth, mycelial lysis, sectoring, barrage and limited production of fruiting bodies in culture. A dsRNA (approximately 6.5 kbp) was associated with isolate 98–18 and other isolates showing abnormal mycelial growth ...

Dynamics of natural hypovirulence in the chestnut blight fungus in Europe
2022In Europe, the mycovirus Cryphonectria hypovirus 1 (CHV-1) acts as a successful biological control agent of the chestnut blight fungus Cryphonectria parasitica. The hypovirus induces a hypovirulent phenotype by reducing parasitic growth and sporulation capacity of its fungal host.

Double-Stranded RNA and Hypovirulence of Endothia Parasitica
1986The concept of biological control as a means of reducing the impact of disease or pest losses is an appealing one. The realization that the chemicals traditionally used to control pests can accumulate and have an adverse impact on the environment has created an interest in biological control as an alternative method of reducing the impact of pests ...

Naturally occurring hypovirulence is necessary for the survival of the chestnut
2015Cryphonectria parasitica Murill Barr is an introduced ascomycete pathogen that caused serious destruction of chestnut trees (Castanea sativa Mill.) in Europe since its introduction in the first half of the XX century. It has spread throughout the entire chestnut areal in Europe and around the Mediterranean.

Biology and Potential for Disease Control of Hypovirulence of Endothia Parasitica
Annual Review of Phytopathology, 1982Low virulent variants of plant pathogens have long been known and cursed by plant pathologists. Early in his education a plant pathologist is taught that before embarking on an experiment he must ensure that his cultures do not lose virulence during the experiment.

Biological control of chestnut blight - Efficiency of natural hypovirulence
2017The mycovirus Cryphonectria hypovirus 1 (CHV-1) infects the ascomycete fungus Cryphonectria parasitica, the causal agent of chestnut blight, an introduced disease of Castanea sativa in Europe. CHV-1 reduces the virulence of C. parasitica against its host tree – a property used in the biological control of the pathogen.
