Ampelovirus

Ampelovirus is a genus of viruses, in the family "Closteroviridae". Plants serve as natural hosts. There are 13 species in this genus. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem.
Taxonomy.
The following species are assigned to the genus:
Structure.
Viruses in the genus "Ampelovirus" are non-enveloped, with flexuous and Filamentous geometries. The diameter is around 10-13 nm, with a length of 1400-2200 nm. Genomes are linear, around 17.9kb in length. The genome codes for 13 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. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. Transmission routes are mechanical.
