''Trichovirus'' is a genus of
viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.

Structure
Viruses in ''Trichovirus'' are
non-enveloped, with flexuous and filamentous geometries. The diameter is around 10-12 nm, with a length of 640-760 nm. Genomes are linear, around 7.5-8.0kb in length. The genome codes for 3 proteins.
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement.
Plants, pome fruits, citrus, and pear serve as the natural host. Transmission routes are grafting.
It is transmitted by mites of the family
Eriophyidae, requiring a
helper virus for transmission.
