ABSTRACT

Micovírus são vírus que infectam todos os taxa de fungos. São geralmente crípticos (latentes), mas podem causar pequenas ou imperceptíveis alterações no hospedeiro. Nos fungos fitopatogênicos, os vírus podem interferir com os sintomas e, em alguns casos, reduzir a virulência de seu hospedeiro; por esta razão, são objeto de estudo, por serem um potencial agente de biocontrole e por serem ferramentas importantes para o conhecimento sobre os mecanismos de patogênese de fungos. A presente revisão teve o objetivo de reunir os dados de literatura relacionados aos aspectos gerais da biologia e do comportamento dos micovírus presentes em alguns fungos fitopatogênicos.(AU)


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.(AU)
