Ampelovirus is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are currently eight species in this genus including the type species Grapevine leafroll-associated virus 3. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem.
Group: ssRNA(+)
Viruses in 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.
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 serve as the natural host. Transmission routes are mechanical.
