name = Fiji disease virus (FDV)
virus_group = iii
familia =Reoviridae
genus = "Fijivirus "
species = Fiji disease virusFiji disease virus (FDV) belongs to the
reoviridae family and infects plants. It is one of the few plant viruses in theReoviridae family. The typespecies of thegenus "Fijivirus ", it is presently the only known member of Fijivirus group 1.tructure
The virus is between 65-70 nm in diameter. FDV is not enveloped but has a nucleocapsid. The capsid has two layers and is icosohedral. The two known cell surface proteins are A type and B type spikes. The capsid appears round.
Genome
As FDV is a reovirus its
genome is also made of dsRNA. The genome is linear and made up of ten segments, consisting of 27000-30500 base pairs. There are at least six structural proteins coded for in the genome. Replication occurs in the host cellcytoplasm or cytoplasmic viroplasma.Transmission
The virus is transmitted by
Delphacidae plant hoppers. The disease is mostly found in Australia because this is the natural habitat of the plant hoppers. It has also been detected in the Philippines. The virus infects the phloem tissues of theirGramineae hosts. Replication can occur in both the host and vector. The result of infection in plants is the development of tumours.References
