The Mycovirus Cryphonectria Hypovirus 1 Infects the Heterologous Host Fusarium oxysporum and Induces Hypovirulence

Plant Pathology, Volume 75, Issue 1, January/February 2026.
The Cryphonectria parasitica hypovirus CHV1 efficiently replicates in the heterologous host Fusarium oxysporum, inducing clear hypovirulence, and has the potential to persist and spread in this pathogen by constant infections and re‐infections through hyphal anastomosis.

Changes in VOCs from a chestnut blight fungus Cryphonectria parasitica by a hypovirus infection: mycoviral infection alters fungal smell for insect vectors

Chemical and Biological Technologies in Agriculture
Background The chestnut blight fungus, Cryphonectria parasitica, and its Cryphonectria hypovirus 1 (CHV1) comprise a useful model system to study fungus–virus interactions.

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 ...

Impact of climate on a host–hyperparasite interaction on Arabica coffee in its native range

Journal of Applied Ecology, Volume 61, Issue 3, Page 538-550, March 2024.
Our findings highlight that coffee leaf rust and its hyperparasite are both affected by shade cover and temperature, but in different ways. On the one hand, these niche differences lead to the worrying prediction that levels of coffee leaf rust will increase, and its hyperparasite will decrease, with climate change.

Characterization of ligninolytic enzymes and metabolic profile of cryphonectria parasitica and the isogenic converted strains by CHV1 hypovirus

, 2019
Cryphonectria parasitica, the causal agent of chestnut blight, causes necrotic lesions (so-called cankers) on the bark of stems and branches of susceptible host trees. Cryphonectria Hypovirus 1 (CHV1) infects C. parasitica and reduces the fungus virulence (hypovirulence) and alters the fungus morphology in culture (pigmentation and sporulation capacity)

CHV1 hypovirus infection on Cryphonectria parasitica - effects on pathogenesis and laccase activity

, 2022
Biological control by hypovirulence is an efficient method to control chestnut blight. The presence of Cryphonectria hypovirus 1 (CHV1) in Cryphonectria parasitica reduces its parasitic growth and sporulation capacity, female fertility, pigmentation, oxalate accumulation and laccase production.
