mycoviruses (antagonists)

This page deals with various viruses infecting plant pathogenic fungi. The mycoviruses covered here belong to several families, like the Alphaflexiviridae, Chrysoviridae, Endornaviridae, Hypoviridae, Partitiviridae, Reoviridae or Totiviridae. Most mycoviruses are RNA viruses but some are DNA viruses. A number of them are of interest as natural biological control agents against fungi infecting crops, specially those that can overcome the defence mechanisms of the plant pathogenic fungi against viruses.

The best studied example of a mycovirus is the "Cryphonectria hypovirus 1" which has been causing widespread recovery in Europe from the chestnut blight fungus Cryphonectria parasitica after its accidental introduction. Other examples are a number of mycoviruses that have been described as infecting the white mold fungus Sclerotinia sclerotiorum, see the page on Sclerotinia mycoviruses.

For a review of mycoviruses see Ghabrial & Suzuki (2009).
