brambyvirus brambyvirus brambyvirus is a genus of viruses, in the family potyviridae. plants serve as natural hosts. there is only one species in this genus: blackberry virus y. brambyvirus virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: pisuviricota class: stelpaviricetes order: patatavirales family: potyviridae genus: brambyvirus structure viruses in brambyvirus are non-enveloped, with flexuous and filamentous geometries. the diameter is around 12-15 nm, with a length of 800 nm. genomes are linear and non-segmented, around 11kb in length. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation brambyvirusfilamentousnon-envelopedlinearmonopartite 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 (unknown). transmission routes are vector. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission brambyvirusplantsnoneviral movement; mechanical inoculationviral movementcytoplasmcytoplasmmechanical inoculation: unknown vector
