Plasmaviridae
family of viruses
Plasmaviridae is a family of bacteria-infecting viruses. Acholeplasma species serve as natural hosts. There is one genus in the family, Plasmavirus, which contains one species: Acholeplasma phage L2 (Plasmavirus L2). All viruses known in this family have been isolated from species in the class Mollicutes.
This family is poorly studied and little is known about the diversity and biology of these viruses.
Taxonomy
The family has one genus, Plasmavirus, which has one recognized member: Acholeplasma phage L2 (Plasmavirus L2).
There are five tentative members of Plasmavirus:
Mycoplasmatales virus-laidlawii 1 (L1)
Mycoplasmatales virus-laidlawii 2 (L2)
Mycoplasmatales virus-laidlawii 3 (L3)
Mycoplasmatales virus-laidlawii 51 (L51)
Mycoplasmatales virus-laidlawii O1 (O1)
Genome
The genome is condensed, nonsegmented and consists of a single molecule of circular, supercoiled double-stranded DNA, 12 kilobase pairs in length. The genome has a rather high G-C content of ~32%. The genome has 14 open reading frames, and encodes at least 15 proteins, of which at least two are structural proteins embedded in the envelope.
Structure
Virions are quasi-spherical, slightly pleomorphic, enveloped and about 80 nm (range 50–125 nm) in diameter.
“Plasmaviridae” enters the record as family of viruses. Crown Archives preserves that source wording while asking what Plasmaviridae, family and viruses can confirm, complicate or overturn.
Why this record matters
“Plasmaviridae” is worth following because a concise public description often conceals a longer documentary argument. Here, Plasmaviridae, family and viruses provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 16, 2026. The linked authority identifier is Q956286. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
