VIRION

image

Non enveloped, large (50 nm diameter) icosahedral particles composed of 420 subunits with a T=7 symmetry . The virion shell is covered with virion associated protein (VAP) . It has not been described whether handedness of capsid is laevo or dextro, here the pictures dsplays a laevo form.

GENOME

image

Monopartite, open circular, double stranded DNA of about 8000 base pairs with discontinuities in both strands: one in the transcribed strand and one to three in the non-transcribed strand. Codes for 6 to 7 proteins.

GENE EXPRESSION

The 35s RNA and its spliced derivatives serves as polycistronic mRNA for viral proteins. Polycistronic translation depends on Tav which is believed to be a translation reinitiation factor. Tav is produced from the monocistronic 19S RNA, the second major viral transcript. Translation of 35S RNA is initiated by ribosome shunt, in which scanning ribosomes bypass leader sequence and multiple short ORFs.

Enzymes: Aspartic protease, Reverse-transcriptase, RNAse H

REPLICATION

CYTOPLASMIC / NUCLEAR

  1. Attachment of viral proteins to host receptors mediates entry into the host cell.
  2. The viral dsDNA is released into the nucleus.
  3. Transcribed by host RNA polymerase II.
  4. mRNA translation produces viral proteins.
  5. Genomic RNA is retrotranscribed into new dsDNA genomes in the cytoplasm.
  6. Genomes are encapsidated by the capsid protein and form new virions.
  7. The virion infects either a new cell by plasmodesmata movement, or by insect vector uptake.
