Suppression of Dollar Spot by Hypovirulent Isolates of Sclerotinia homoeocarpa [PDF]

Phytopathology®, 1998
Selected hypovirulent isolates of Sclerotinia homoeocarpa were evaluated for efficacy in suppressing dollar spot of turfgrass under growth room and field conditions. Under growth room conditions, hypovirulent isolates Sh12B, Sh09B, or Sh08D of S. homoeocarpa caused 3.4 to 30.4% diseased turf in comparison to virulent isolates Sh48B and Sh14D, which ...

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.

Phenotypic and Molecular Investigations on Hypovirulent Cryphonectria parasitica in Italy [PDF]

Plant Disease, 2018
Chestnut blight is caused by the fungus Cryphonectria parasitica. As one of the most ecologically important diseases of Castanea spp., C. parasitica can rapidly kill trees. In Europe, mitigation of disease severity took place spontaneously through colonization of C. parasitica by mycoviruses, which reduced the virulence of the fungus. In the framework

Persistence of microbiological hazards in food and feed production and processing environments

EFSA Journal, Volume 22, Issue 1, January 2024.
Abstract Listeria monocytogenes (in the meat, fish and seafood, dairy and fruit and vegetable sectors), Salmonella enterica (in the feed, meat, egg and low moisture food sectors) and Cronobacter sakazakii (in the low moisture food sector) were identified as the bacterial food safety hazards most relevant to public health that are associated with ...

Risk assessment and reduction options for Cryphonectria parasitica in the EU

EFSA Journal, 2016
Following a request from the European Commission, the EFSA Plant Health (PLH) Panel performed a risk assessment for Cryphonectria parasitica in the EU with the aim to assess the current EU phytosanitary requirements and identify the risk reduction ...

A Novel Partitivirus in the Hypovirulent Isolate QT5-19 of the Plant Pathogenic Fungus Botrytis cinerea

Viruses, 2019
A pink isolate (QT5-19) of Botrytis cinerea was compared with three gray isolates of B. cinerea for growth and morphogenesis on potato dextrose agar (PDA), and for pathogenicity on tobacco.

Transmissible hypovirulent element in isolate Ep-1PN ofSclerotinia sclerotiorum

Chinese Science Bulletin, 1998
The cause of virulence decline of hypovirulent isolate Ep-1PN ofSclerotinia sclerotiorum (Lib.) de Bary has been studied through transmitting test and analysing its offsprings derived from single ascospore. When the colony of a normal strain Ep lPNA 183 intermingled with the colony of Ep-lPN, its margin became abnormal, just like EplPN.

A novel virus that infecting hypovirulent strain XG36-1 of plant fungal pathogen Sclerotinia sclerotiorum

Virology Journal, 2009
Background Sclerotinia sclerotiorum is a notorious plant fungal pathogen which spreads across the world. Hypovirulence is a phenomenon where the virulence of fungal pathogens is decreased, even lost, due to mycovirus infection.
