Replication may occur in the cytoplasm, nuclei, chloroplasts, Golgi apparatus, cell vacuoles or more rarely in unusual sites.

Potyviruses make proteinacous inclusions in infected plant cells.
 These may be crystals in either the cytoplasm or in the nucleus, as amorphous X-bodies, membranous bodies, viroplasms or  pinwheels.
The inclusions may or may not (depending on the species) contain virions.
These inclusions can be seen in the light microscope in leaf strips of infected plant tissue stained with Orange-Green (protein stain) but not Azure A (nucleic acid stain).
There are four different kinds of Potyvirus inclusions.

Replication follows the positive stranded RNA virus replication model.
Positive-stranded RNA virus transcription is the method of transcription.
Translation takes place by -1 ribosomal frameshifting.
The virus exits the host cell by tubule-guided viral movement.
Plants serve as the natural host.
The virus is transmitted via a vector (insects).
Transmission routes are vector and mechanical.
