Abstract

The family Hadakaviridae, including the genus Hadakavirus, accommodates capsidless viruses with a 10- or 11-segmented positive-sense (+) RNA genome. Currently known hosts are ascomycetous filamentous fungi. Although phylogenetically related to polymycovirids with a segmented double-stranded RNA genome and certain encapsidated picorna-like viruses, hadakavirids are distinct in their lack of a capsid ('hadaka' means naked in Japanese) and their consequent inability to be pelleted by conventional ultracentrifugation; they show ribonuclease susceptibility in host tissue homogenates. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Hadakaviridae, which is available at ictv.global/report/hadakaviridae.

Keywords: Hadakaviridae; ICTV Report; taxonomy.

Fig. 1.. Genome organization of hadaka virus 1 isolate 7 n (LC519840–50). Open reading frames are indicated by boxes. The three genes homologous between hadakavirids and polymycovirids are coloured pink: P1 (RdRP, RNA-dependent RNA polymerase), P2 (unknown function) and P3 (MTR, methyltransferase). Other coloured regions indicate conserved domains or motifs identified previously [1]
