Prunevirus (taxid:1914295)



Non-enveloped, flexuous, filamentous, about 960 nm long and 12 nm in diameter.



Linear ssRNA(+) genome of 8.7 kb in size. The 5' end is capped and 3' terminus is polyadenylated. Encodes 4 ORFs.


The virion RNA is infectious and serves as both the genome and viral messenger RNA. RNA-dependent RNA polymerase (RdRp) is translated directly from the genomic RNA. The putative movement protein (ORF2) and capsid (ORF3) proteins are transcribed from subgenomic mRNAs (sgRNAs). RBP is a RNA-binding protein.




  1. Virus penetrates into the host cell.
  2. Uncoating, and release of the viral genomic RNA into the cytoplasm.
  3. The viral RNA is translated as a monocistronic mRNA to produce the RdRp (encoded by the 5'-proximal ORF).
  4. Replication occurs in viral factories. A dsRNA genome is synthesized from the genomic ssRNA(+).
  5. The dsRNA genome is transcribed/replicated thereby providing viral mRNAs/new ssRNA(+) genomes.
  6. Internal subgenomic promoters are used to transcribe the sgRNAs. Traduction of these sgRNAs yields the capsid and movement proteins.
  7. Assembly of new virus particles.
  8. Movement protein allows cell-to-cell movement.
These structures were created with the help of Colabfold by Jason Nomburg, Nathan Price and Jennifer Doudna (ModelArchive).
