Saccharomyces Cerevisiae Virus L-A - Similarity of L-A To Animal DsRNA Viruses

Similarity of L-A To Animal DsRNA Viruses

Animal and plant dsRNA viruses have up to three capsid layers, with structures adapted to protect the virus in its extracellular travels, to facilitate uptake by specific target cells and to engineer the uncoating of the outer layers after uptake. The yeast L-A virus can dispense with much of this apparatus because of its strictly intracellular life cycle. However, both L-A and plant and animal dsRNA viruses synthesize both (+) and (–) viral RNA strands within particles. The core particles in the case of the animal viruses and the structures of these inner nucleoprotein particles are similar.
