Mandarivirus
Mandarivirus is a genus of viruses in the order Tymovirales, in the family Alphaflexiviridae. There are currently only two species in this genus including the species Indian citrus ringspot virus. Diseases associated with this genus commonly include yellow ringspot and rapid decline of the tree.[1][2]

Structure
Viruses in Mandarivirus are non-enveloped, with flexuous and filamentous geometries. The diameter is around 13 nm. Genomes are linear, around 7.5kb in length. The genome codes for 6 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 tripartite non-tubule guided viral movement. Citrus trees serve as the natural host with grafting being a common transmission route.[1]
