Bymovirus

Bymovirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are currently six species in this genus including the type species Barley yellow mosaic virus.[1][2]

Structure

Viruses in Bymovirus are non-enveloped, with flexuous and Filamentous geometries. The diameter is around 12-15 nm, with a length of 500-600 and 200-300 nm. Genomes are linear and bipartite, around 23.5-3.8kb in length.[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 tubule-guided viral movement. Plants serve as the natural host. The virus is transmitted via a vector (fungus; plasmodiophorales). Transmission routes are vector, mechanical, and oral.[1]
