Notes on Genus: Plectrovirus

flexuous filaments
flexuous filaments

Type member: Acholeplasma phage MV-L51


General Description

This is one of the genera in the family Inoviridae. Members are distinguished by having more or less rod-shaped particles and because they infect spiroplasmas.


Virions are nearly straight, rod-shaped, 10-16 nm in diameter and 70-280 nm (or more) long. One end is rounded and the attachment end is more variable in morphology.


Monopartite, circular, positive sense, ssDNA, 4.5-8.5 kb in length.

Genus Genomic Organization

There are 4 ORFs, including the major capsid protein of about 19 kDa. In phage L1 these ORFs are:
  1. 12.2 kDa
  2. 18.7 kDa, probably the major capsid protein
  3. 23.3 kDa
  4. 30.9 kDa

Type Member Genomic Organization

There are no sequence data for the type member.
