Summary
The Mymonaviridae family comprises filamentous viruses infecting fungi. One notable virus causes hypovirulence in its fungal host, impacting plant health.
Area of Science:
- Virology
- Mycology
- Plant Pathology
Background:
- Mymonaviridae are filamentous, enveloped viruses with negative-sense RNA genomes.
- The family currently contains one genus, Sclerotimonavirus.
- These viruses primarily infect filamentous fungi.
Purpose of the Study:
- To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the Mymonaviridae family.
- To provide an overview of the taxonomy and characteristics of Mymonaviridae.
Main Methods:
- Review and synthesis of information from the ICTV report.
- Analysis of viral morphology, genome structure, and host interactions.
Main Results:
- Mymonaviridae virions are filamentous and enveloped, containing a single linear negative-sense RNA molecule (approx. 10 kb).
- Sclerotimonavirus is the sole genus within the family.
- Sclerotinia sclerotiorum negative-stranded RNA virus 1 is a known member that induces hypovirulence in its fungal host.
Conclusions:
- The Mymonaviridae family represents a distinct group of fungal viruses.
- Understanding these viruses is crucial for managing fungal diseases, particularly through the phenomenon of hypovirulence.
- The ICTV report provides a standardized classification for Mymonaviridae.

Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.

Plaquing is a routine method used to quantify live viruses in a population. Though plaquing is frequently taught in various microbiology curricula with bacteria and bacteriophages, plaquing of mammalian viruses is more complex and time-consuming. This protocol describes the procedures that function reliably for regular work with herpes simplex...
