Rhizidiovirus is a genus of viruses. Stramenopiles[1] (specifically Hyphochytridiomycota) serve as natural hosts. There is only one species in this genus: Rhizidiomyces virus.[2][3]

Structure

Schematic drawing of a Rhizidiovirus particle

Viruses in Rhizidiovirus are non-enveloped, with icosahedral, round, and isometric geometries. The diameter is around 60 nm.[2]

The genome is non segmented, linear double stranded DNA (dsDNA) and ~25.5 kilobases in length. It encodes at least 14 protein with molecular weights between 84.5 and 26 kilodaltons.[1]

Life cycle

The virus seems to remain latent within the host until the host is stressed.[4]

DNA-templated transcription is the method of transcription. Fungi and hyphochytridiomycota serve as the natural host.[2]
