Notes on Genus: Mycoflexivirus
Type member: Botrytis virus F
This is currently the only genus in the family Gammaflexiviridae
. The name reflects the fact that the species classified has flexuous virions and infects fungi.
Virions filamentous, flexuous, not enveloped, about 720 nm long and 12-13 nm in diameter.
Monopartite, linear, polyadenylated ssRNA of 6.8 kb. There is a large replication protein with a polymerase domain expressed by readthrough of a 'leaky' stop codon and a coat protein presumably expressed from a subgenomic mRNA.
