(unranked): incertae sedis
Family: Botourmiaviridae
Genus: Ourmiavirus
Type species
Ourmia melon virus

Ourmiavirus is a genus of viruses. Cucurbits, cherry, and cassava serve as natural hosts. There are currently three species in this genus including the type species Ourmia melon virus.[1][2] Diseases associated with this genus include: ouMV: yellowing and chlorotic spot symptoms.[1][2][3][4]


Viruses in Ourmiavirus are non-enveloped, with icosahedral and Bacilliform geometries, and T=1 symmetry. The diameter is around 18 nm, with a length of 30 nm. Genomes are linear and segmented, around 2.8kb in length.[1][2][3]

Life cycle[edit]

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. Cucurbits, cherry, and cassava serve as the natural host.[1][2][3]
