Endornaviridae
Endornaviridae is a family of viruses. Plants, fungi, and oomycetes serve as natural hosts. There are currently 31 species in this family, divided among 2 genera (Alphaendornavirus and Betaendornavirus).[1][2][3][4]

Taxonomy
The following genera are recognized:
- Alphaendornavirus; type species: Oryza sativa alphaendornavirus; 24 species
- Betaendornavirus; type species: Sclerotina sclerotiorum betaendornavirus 1; 7 species
Structure
Linear, single-stranded, positive-sense RNA genome of about 14 kb to 17.6 kb. A site specific break (nick) is found in the coding strand about 1 to 2 kb from the 5’ terminus. ViralZone conflicts with ICTV, listing Endornaviridae as dsRNA viruses.[1][2]
Life cycle
Viral replication is cytoplasmic. Replication follows the double-stranded RNA virus replication model. Double-stranded rna virus transcription is the method of transcription. The virus exits the host cell by cell to cell movement. Plants, fungi, and oomycetes serve as the natural host. Transmission routes are pollen associated.[1][2]
