Enamovirus
Enamovirus is a genus of viruses, in the family Solemoviridae. Plants serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: pea enation disease: if both PEMV-1 and PEMV-2 are present.[1][2]

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. Translation takes place by leaky scanning, -1 ribosomal frameshifting, and suppression of termination. 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.[1]
