Tobamovirus

Molecular biology

VIRION

Non-enveloped, rigid helical rods with a helical symmetry. Virion is about 18 nm in diameter, and 300-310 nm in length.

GENOME

Monopartite, linear, ssRNA(+) genome of 6.3-6.5 kb. The 3’-terminus has a tRNA-like structure. The 5’ terminus has a methylated nucleotide cap (m7G5’pppG).

GENE EXPRESSION

Genomic RNAs serve as messenger RNA. Subgenomic RNAs may be synthesized during replication of RNA-3. The small replicase is involved in replication and acts as suppressor of RNA silencing. A ribosomal readthrough on RNA-1 produces the RNA-dependent-RNA polymerase. A movement proteins and the capsid protein are expressed from separate subgenomic mRNAs.

REPLICATION

CYTOPLASMIC

  1. Virus penetrates into the host cell.
  2. Uncoating, and release of the viral genomic RNA into the cytoplasm.
  3. Genomic RNA is translated to produce the two proteins necessary for replication.
  4. A negative-sense complementary ssRNA is synthesized using the genomic RNA as a template.
  5. New genomic RNA is synthesized using the negative-sense RNA as a template, as well as subgenomic RNA encoding for MP and CP proteins.
  6. Assembly of new virus particles.
