ICTV Virus Taxonomy Profile: Tosoviridae 2023.

ABSTRACT

Tosoviridae is a family of negative-sense RNA viruses with genomes totaling about 12.3 kb that have been found in turtles. The tosovirid genome consists of two segments, each with two open reading frames (ORFs) in ambisense orientation. The small (S) segment encodes a nucleoprotein (NP) and a glycoprotein precursor (GPC); the large (L) segment encodes an L protein containing an RNA-directed RNA polymerase (RdRP) domain and a zinc-binding (Z) protein. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Tosoviridae, which is available at ictv.global/report/tosoviridae.
