Oxalate production by virulent but not by hypovirulent strains of Endothia parasitica
Physiological Plant Pathology, 1983Abstract Three virulent strains of Endothia parasitica when grown on potato dextrose agar containing methionine and biotin (PDAmb) or minimal media containing glucose supplemented with either glycolate or glyoxylate produced 10–12, 50–60 and 20–40 mg oxalate g−1 dry weight of fungus respectively. Oxalate accumulation was detected the fourth day after

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 ...

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.

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.

Hypovirulence and Chestnut Blight: From the Field to the Laboratory and Back
2000Most of the pathogenic fungi discussed in this book have been reported to harbor viral-like double-stranded (ds) RNAs (Buck, 1986; Nuss and Koltin, 1990; Ghabrial, 1998). Correlation between the presence of extrachromosomal dsRNAs and attenuation of virulence (hypovirulence) for some pathogenic fungi have stimulated interest in these elements as ...
