Ophiovirus citri
Assigned virus:
• citrus psorosis virus (CPsV)
CPsV causes psorosis on citrus which is characterized by scaling of the outer layer of the bark (the inner bark remains green). Decline of the tree and possible death follows. The virus is transmitted through grafting and aphids.
The genome consists of 3 negative-stranded RNAs with sizes of around 8,185, 1,645 and 1,455 nt. RNA1 encodes 3 ORFs, RNA2 the virus movement protein and RNA3 the coat protein.

Two different forms of the citrus psorosis disease have been described and have been called psorosis A and porosis B. Porosis A has milder symptoms, where the lesions are typically limited to some areas of the stem and the main branches. In porosis B the lesions are common and large portions of the bark are shed. The virus associated with the severe form (porosis B) has been referred to as 'citrus ringspot virus'. However 'citrus ringspot virus' is now regarded as a synonym of 'citrus psorosis virus' and should not be confused with the 'Indian citrus ringspot virus', an unrelated virus.
