ICTV Virus Taxonomy Profile: Mymonaviridae 2022

Area of Science:

• Virology
• Mycology
• Plant Pathology

Background:

• Mymonaviridae are enveloped viruses with negative-sense RNA genomes.
• These viruses primarily infect filamentous fungi but have also been found in other organisms.
• Some Mymonaviridae members are known to induce hypovirulence in their hosts.

Purpose of the Study:

• To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the Mymonaviridae family.
• To provide an overview of Mymonaviridae taxonomy, characteristics, and host associations.

Main Methods:

• Review and synthesis of data from the ICTV report.
• Classification and characterization of Mymonaviridae based on existing literature and genomic data.

Main Results:

• Mymonaviridae typically produce filamentous, enveloped virions with single-stranded RNA genomes.
• The family includes multiple genera and species with diverse host ranges, including fungi, insects, oomycetes, and plants.
• Sclerotinia sclerotiorum negative-stranded RNA virus 1 is an example of a mymonavirid that causes hypovirulence.

Conclusions:

• Mymonaviridae represent a significant viral family with implications for fungal pathogens and plant health.
• Understanding Mymonaviridae diversity and impact is crucial for disease management and biological control strategies.
