orchid fleck virus
The Orchid Fleck Virus (OFV) is a non-enveloped, segmented, single-stranded (ss) RNA negative-strand virus, transmitted by the false spider mite, ''Brevipalpus californicus''.
OFV causes necrotic and chlorotic lesions on the leaves〔(''Image'') Kubo KS, Freitas-Astu´a J, Machado MA, Kitajima EW 2009. Orchid fleck symptoms may be caused naturally by two different viruses transmitted by Brevipalpus. '' J Gen Plant Pathol '' 75:250–255.〕 of many genera in the family ''Orchidaceae''
==Introduction==
Orchid Fleck Virus, despite its presence worldwide, only affects a small spectrum of human life. Orchids are not used for food but rather serve mainly as ornamental decoration. Therefore only about 2 to 3 scientific reports are written about OFV each year. The whole genome of OFV has been sequenced and its six main protein products have been sequenced as well.〔Kondo H, Maeda T, Shirako Y, Tamada T 2006. Orchid fleck virus is a rhabdovirus with an unusual bipartite genome. J Gen Virol 87:2413–2421.〕
Much is still not known about OFV including how exactly and why vector mites travel from orchid to orchid, and more host species of flowers are being discovered annually. The more information researchers discover, the more they realize there is still much left to learn. Many orchid enthusiasts are participating in "citizen science" by posting their OFV-related findings on international horticulture blogs and forums.
