Notes on Genus: Mycoreovirus
Type member: Mycoreovirus 1
This genus is the only one in the family Reoviridae
to consist of viruses that infect fungi (hence the name).
Virions isometric (icosahedral), c
.80 nm in diameter, with two concentric capsid shells surrounding a core that contains 12 surface projections that connect the inner and outer capsid layers.
Linear, double stranded RNA in 11 or 12 segments. Each virion contains a single copy of the entire genome. The 3' terminus has neither a poly(A) tract nor a tRNA-like structure. All RNA segments have highly conserved nucleotide sequences at the 3'- and 5'-termini.
Genus Genomic Organization
Each segment contains a single ORF with the RNA polymerase translated from the largest segment.
Type Member Genomic Organization
Each segment has one open reading frame:
|Segment || Size (nt) || Protein (kDa) |
