Program for chestnut blight biocontrol based on hypovirulence
, 2018 Chestnut Blight is an introduced disease in Portugal associated with virulent strains of the Asian fungus Cryphonectria parasitica (Murril) Barr. The disease causes great economic losses and presents a significant risk to the chestnut ecosystem. Eradication efforts and cultural sanitary measures didn’t control the disease and actually more than 10% of ...

Potato Virus Y Restricts Alternaria solani Growth During Co-Infection
Molecular Plant-Microbe InteractionsIn the environment, multiple microbes can interact with each other in the plant phyllosphere. These associations can shape the plant's development, stress responses, and disease susceptibility, but the molecular mechanisms that govern this process remain

SPREAD OF INTRODUCED HYPOVIRULENCE VS. NATURAL HYPOVIRULENCE IN CHESTNUT BLIGHT
Acta Horticulturae, 2010Cryphonectria parasitica was found for the first time in Greece in 1963 in Mount Pelion (Central Greece). In a short time the disease of chestnut blight devastated 500 ha of orchard land across the mountain. In 1986, hypovirulence attributed to CHV1 hypoviruses was detected on a single tree at the southern edge of the chestnut area.

Current Genetics, 2003
A double-stranded (ds)RNA, designated as M2, is associated with hypovirulence, conversion of the quinic acid pathway from inducible to constitutive and downregulation of the shikimic acid pathway in the Rhizoctonia solani culture Rhs 1A1. In this study, we report that in the virulent, M2-lacking isolate Rhs 1AP, which is isogenic to Rhs 1A1, quinic ...

BIOLOGICAL CONTROL OF CHESTNUT BLIGHT WITH HYPOVIRULENCE: A Critical Analysis
Annual Review of Phytopathology, 2004▪ Abstract Most hypovirulence in the chestnut blight fungus, Cryphonectria parasitica, is associated with infection by fungal viruses in the family Hypoviridae. Hypovirulence has controlled chestnut blight well in some locations in Europe and in Michigan in the United States.

Hypovirulence: Mycoviruses at the fungal–plant interface
Nature Reviews Microbiology, 2005Whereas most mycoviruses lead 'secret lives', some reduce the ability of their fungal hosts to cause disease in plants. This property, known as hypovirulence, has attracted attention owing to the importance of fungal diseases in agriculture and the limited strategies that are available for the control of these diseases.

Transmissible hypovirulence inSclerotinia minor
Canadian Journal of Plant Pathology, 1996Thirty isolates of Sclerotinia minor were collected from a 4 ha commercial lettuce crop at Holland Marsh, Ontario, and examined for the presence of transmissible hypovirulence. Three slow-growing isolates with atypical colony morphology were less virulent (P = 0.05) on detached lettuce leaves than other isolates and were considered hypovirulent.
