Blackberry and raspberry are members of the family Rosaceae. They are
classified in the genus Rubus, which comprises hundreds of species and
has a center of origin in the Far East. Rubus is divided into 15
subgenera with blackberries classified in the Rubus (formerly Eubatus)
and raspberries in the Idaeobatus subgenera. Rubus species are
propagated vegetatively and are subject to infection by viruses during
development, propagation, and fruit production stages. Reports of initial
detection and symptoms of more than 30 viruses, virus-like diseases, and
phytoplasmas affecting Rubus spp. were reviewed more than 20 years ago.
Since the last review on Rubus viruses, significant progress has been
made in the molecular characterization of many of the viruses that infect
Rubus spp. Currently, reverse transcription–polymerase chain reaction
detection methods are available for most of the viruses known to infect Rubus.
The goals of this article are to update the knowledge on previously
characterized viruses of Rubus, highlight recently described viruses,
review the virus-induced symptoms, describe the advances made in their
detection, and discuss our knowledge about several virus complexes that cause
serious diseases in Rubus. Virus complexes have been identified recently
as the major cause of diseases in blackberries and raspberries.
