Type Species
  • Shallot virus X

Allexivirus is a genus of viruses in the order Tymovirales, in the family Alphaflexiviridae. Shallot, onion, and garlic serve as natural hosts. There are currently eight species in this genus including the type species Shallot virus X. Diseases associated with this genus include: mosaic and ringspot symptoms.[1][2]

Structure

Viruses in Allexivirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12 nm, with a length of 800 nm. Genomes are linear, around 9kb in length. The genome codes for 6 proteins.[1]

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 tripartite non-tubule guided viral movement. Shallot, onion, and garlic serve as the natural host. The virus is transmitted via a vector (mite). Transmission routes are vector and mechanical.[1]
