''Cucumovirus'' is a genus of
virus
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 the genus ''Cucumovirus'' are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The diameter is around 29 nm. Genomes are linear and segmented, tripartite.
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, using the internal initiation model of subgenomic rna transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. Transmission routes are mechanical and contact.
Epidemiology
It is thought that cucumoviruses are present worldwide, being known to occur in Eurasia, Australia, Canada, France, India, Japan, North and South Korea, Morocco, New Zealand, Poland, Spain, the US, and the former USSR. Its natural hosts belong to the domain Eukaryota
Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the ...
