- Abstract
The family Roniviridae includes the genus Okavirus for three species of viruses with enveloped, rod-shaped virions. The monopartite, positive-sense ssRNA genome (26-27âkb) contains five canonical long open reading frames (ORFs). ORF1a encodes polyprotein pp1a containing proteinase domains. ORF1b is expressed as a large polyprotein pp1ab by ribosomal frameshifting from ORF1a and encodes replication enzymes. ORF2 encodes the nucleoprotein. ORF3 encodes two envelope glycoproteins. ORFX encodes a putative double membrane-spanning protein. Roniviruses infect shrimp but only yellow head virus is highly pathogenic. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Roniviridae , which is available at ictv.global/report/roniviridae.
