Varicosavirus

VIRION

Virions have rod-shaped particles with modal lengths of 320-360 nm and diameters of 18 nm. They do not have an envelope structure.

GENOME

The genome is segmented; bipartite. After deproteinization of purified virions, both single stranded and double stranded RNA are detected.

GENE EXPRESSION

These viruses contain a single coat protein (CP) with an Mr of approximately 48 kDa and do not possess an envelope structure.

REPLICATION

CYTOPLASMIC

  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.
