Summary

The family Konkoviridae includes plant viruses with segmented ssRNA(-) genomes; some viruses may have both ssRNA(-) and ssRNA(+/-) segments (Table 1 Konkoviridae). The family Konkoviridae was established in 2024 (Master Species List #39).

Derivation of names

Konkoviridae: from the Japanese Ukonko (鬱金香), meaning “tulip”, referring to the host of a member of the family; the suffix viridae for family taxa

Olpivirus: after the fungal vector genus Olpidium, by which tulip streak virus is transmitted
