ICTV Virus Taxonomy Profile: Open Access

Abstract

is a family of non-enveloped spherical viruses with dsRNA genomes of two linear segments, each of 7.2–8.9 kbp, comprising 16.1 kbp in total. The genus includes the species , the exemplar isolate of which infects the white root rot fungus () to which it confers hypovirulence. Megabirnaviruses are characterized by their bisegmented genome with large 5′-untranslated regions (1.6 kb) upstream of both 5′-proximal coding strand ORFs, and large protrusions on the particle surface. This is a summary of the ICTV Report on the family , which is available at ictv.global/report/megabirnaviridae.

This Profile is dedicated to the memory of our valued colleague Professor Said A. Ghabrial.
