Albetovirus
genus of virus
Albetovirus is a plant satellite virus genus. As a member of realm Riboviria without assigned family or order it contains just three species, Tobacco albetovirus 1, 2, and 3 (alias Satellite tobacco necrosis virus 1, 2, respectively C). The three virus species included in this genus represent satellite viruses that depend for their replication on helper viruses of the genera Alphanecrovirus or Betanecrovirus (prior to 2011 together referred to as Necrovirus, family Tombusviridae)
These satellite viruses may not be confused with Satellite tobacco mosaic virus, which is also known as Satellite tobacco necrosis virus (just that), member of genus Virtovirus.
Etymology
The genus name, Albetovirus, is a combination of Al, for Alphanecrovirus, be, for Betanecrovirus, and to for tobacco..
Virology
Viruses of genus Albetovirus have a genome consisting of linear single-stranded RNA of positive polarity, similar in size (1221 to 1245 nucleotides long), which has a single gene. This codes for a single protein which is the capsid protein. The virions are non-enveloped, paraspherical in shape with icosahedral symmetry and 17 nm in diameter.

“Albetovirus” enters the record as genus of virus. Crown Archives preserves that source wording while asking what Albetovirus, genus and virus can confirm, complicate or overturn.
Why this record matters
“Albetovirus” is worth following because a concise public description often conceals a longer documentary argument. Here, Albetovirus, genus and virus provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jan 9, 2026. The linked authority identifier is Q24806042. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2011, 1221, 1245 and 2000.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “Albetovirus”, its source revision and the description used here.
- Expand the search: follow Albetovirus primary sources, Albetovirus archive and Albetovirus research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
