Interpretive Summary:

Technical Abstract: The family Alphaflexiviridae contains viruses with flexuous filamentous virions that are 470–800 nm or more in length and 12–13 nm in diameter. Alphaflexiviruses have a single stranded, positive sense RNA genome of 5.4–9 kb. They infect plants and plant-infecting fungi. They share a distinct lineage of alphavirus-like replication proteins that is unusual in lacking any recognized protease domain. With a single exception, cell-to-cell and long-distance movement is facilitated by triple gene block proteins in plant infecting genera. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Alphaflexiviridae which is available at www.ictv.global/report/alphaflexiviridae.
