Subviral agents

The following agents are smaller than viruses but have some of their properties.

Viroids

• Family Avsunviroidae
  • Genus Avsunviroid; type species: Avocado sunblotch viroid
  • Genus Pelamoviroid; type species: Peach latent mosaic viroid
  • Genus Elaviroid; type species: Eggplant latent viroid'
• Family Pospiviroidae
  • Genus Pospiviroid; type species: Potato spindle tuber viroid
  • Genus Hostuviroid; type species: Hop stunt viroid
  • Genus Cocadviroid; type species: Coconut cadang-cadang viroid
  • Genus Apscaviroid; type species: Apple scar skin viroid
  • Genus Coleviroid; type species: Coleus blumei viroid 1

Satellites

Satellites depend on co-infection of a host cell with a helper virus for productive multiplication. Their nucleic acids have substantially distinct nucleotide sequences from either their helper virus or host. When a satellite subviral agent encodes the coat protein in which it is encapsulated, it is then called a satellite virus.

• Satellite viruses
  • Single-stranded RNA satellite viruses
    • Subgroup 1: Chronic bee-paralysis satellite virus
    • Subgroup 2: Tobacco necrosis satellite virus
• Satellite nucleic acids
• Single-stranded satellite DNAs
• Double-stranded satellite RNAs
• Single-stranded satellite RNAs
  • Subgroup 1: Large satellite RNAs
  • Subgroup 2: Small linear satellite RNAs
  • Subgroup 3: Circular satellite RNAs (virusoids)

Prions

Prions, named for their description as "proteinaceous and infectious particles", lack any detectable (as of 2002) nucleic acids or virus-like particles. They resist inactivation procedures that normally affect nucleic acids.

• Mammalian prions:
  • Agents of spongiform encephalopathies
• Fungal prions:
  • PSI+ prion of Saccharomyces cerevisiae
  • URE3 prion of Saccharomyces cerevisiae
  • RNQ/PIN+ prion of Saccharomyces cerevisiae
  • Het-s prion of Podospora anserina
