Capillovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants, pome fruits, citrus, and pear serve as natural hosts. There are eight species in this genus. Diseases associated with this genus include: abnormal graft union, possibly black necrotic leaf spot disease.[1][2]

Structure
Viruses in Capillovirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 12 nm, with a length of 640 nm. Genomes are linear, around 6.5-7.5kb in length. The genome codes for 3 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 tubule-guided viral movement. Plants, pome fruits, citrus, and pear serve as the natural host. The virus is transmitted via a vector (by seeds and no known). Transmission routes are vector, mechanical, and seed borne.[1]
