Virus infecting phytopathogenic fungi

ABSTRACT: Mycovirus are viruses that infect all taxa of fungi. They are generally cryptic or latent, but they can induce minor or imperceptible changes in hosts. Mycoviruses can interfere with the symptoms induced by phytopathogenic fungi hosts, and in some cases they reduce the virulence of its host. Therefore, they are objects of study since they are potential biocontrol agents and are important tools for knowledge of fungal pathogenesis mechanisms. The aim of this review was to gather literature data concerning general aspects of biology and behavior of mycovirus, focusing some phytopathogenic mycovirus.
