Biological Control of Chestnut Blight in Portugal
Hypovirulence is a specific biological control method of chestnut blight, a lethal disease of American and European chestnut. The causal pathogen of chestnut blight is Cryphonectria parasitica, a fungus of Asian origin and an A2 quarantine organism in Europe. The disease has been reported since 1990 in Portugal, one of the last European countries where the pathogen was introduced. The chestnut ...
متن کاملBiological control of chestnut blight with hypovirulence: a critical analysis.
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. In contrast, with few exceptions, biological control has failed almost completely in eastern North America. Therapeutic treatment o...
متن کاملHypovirulence: Use and Limitations as a Chestnut Blight Biological Control
The recovery of chestnut from chestnut blight in Italy and Michigan largely was responsible for the resurgence in chestnut research. The observed remission of disease now has been attributed to a biological control process called hypovirulence, whereby virulent strains are debilitated as a result of infection by fungal viruses (hypoviruses). Several species of hypoviruses now are known and each...
متن کاملEngineering super mycovirus donor strains of chestnut blight fungus by systematic disruption of multilocus vic genes.
Transmission of mycoviruses that attenuate virulence (hypovirulence) of pathogenic fungi is restricted by allorecognition systems operating in their fungal hosts. We report the use of systematic molecular gene disruption and classical genetics for engineering fungal hosts with superior virus transmission capabilities. Four of five diallelic virus-restricting allorecognition [vegetative incompat...
متن کاملCharacteristics of Hypovirulent Strains of Chestnut Blight Fungus, Cryphonectria parasitica, Isolated in Korea
Chestnut blight disease caused by Cryphonectria parasitica is widely distributed throughout chestnut tree plantations in Korea. We surveyed 65 sites located at 9 provinces in South Korea, and isolated 248 virulent and 3 hypovirulent strains of chestnut blight fungus. Hypovirulent strains had dsRNA virus in the cytoplasm, which is one of the typical characteristics of hypovirulent strains. In ad...
