Molecular biology


Virions consist of four to five non enveloped nucleocapsids, about 3-10 nm in diameter


The genome is segmented and consists of four or five segments of linear negative-sense and ambisense single-stranded RNA. The complete genome is around 16 kb.


Segments 2, 3 and 4 are ambisens.



  1. Virus enters into host cells by mechanical injection or through plasmodesmatas
  2. Transcription, viral mRNAs are capped in the cytoplasm.
  3. Replication presumably starts when enough nucleoprotein is present to encapsidate neo-synthetized antigenomes and genomes.
  4. The ribonucleocapsids migrates to new cells using movement proteins.
