11 Mag The amazing mycovirome of the necrotrophic fungus Botrytis cinerea
The fungus Botrytis cinerea (Ascomycota) infects over 200 plant species, causing annual losses of $10 billion to $100 billion. It is responsible for the grey mould disease, evident on the plant surface as grey fluffy mycelium. Since B. cinerea can develop fungicide resistance, there is interest in the possible use of mycoviruses in biological controls, as alternative to chemical control.
Researchers from Spain and Italy produced the most extensive and wide diversity collection of mycoviruses infecting B. cinerea, which will be the basis to develop products based on microorganisms to be used in biocontrol strategies.
