''Cymbidium mosaic virus'' (CymMV) is a plant pathogenic virus of the family ''Alphaflexiviridae''. ''Cymbidium mosaic virus'' and the ''Odontoglossum ringspot virus'' (ORSV) are two of the most common viruses affecting cultivated orchids worldwide. Infected plants can have less desirable flowers or other problems, causing significant financial losses to orchid growers. The virus has not often been reported in wild orchid populations. It can be found in a wide variety of orchid genera but does not infect plants other than orchids.〔 Once an orchid is infected, the virus spreads throughout the infected plant in a number of weeks. Control measures may include sanitizing pruning equipment between plants.〔 There is an ELISA test available to test for presence of the virus.〔 It is related to the ''Narcissus mosaic virus'' (NMV), the ''Scallion virus X'' (SVX), the ''Pepino mosaic virus'' (PepMV) and the Potato aucuba mosaic virus (PAMV).〔 ==Importance== Orchids are composed of nearly 200,000 species of plants with attractive flowers. They are predominantly found in wet climates. The orchid family is one of the most important plant families in respect to the ornamental flower industry. In 2005, the potted orchid industry brought in about $144 million in the United States. This makes them the second most valuable potted plant in the nation. From 1996 to 2006 there has been a 206.4% increase in potted orchid prices. Globally, Taiwan, Taipei, Thailand, the United Kingdom, Italy, Japan, Brazil, and New Zealand are among the largest importers of potted orchids.〔(【引用サイトリンク】url=http://www.hrt.msu.edu/faculty/Runkle/Orchid/Orchid_Research.htm )〕 Additionally, orchids are the source of vanilla. It is the only commercially important derivation from the plants - most commonly found in the ''Vanilla planifolia'' species. Certain orchids are also used in homeopathic treatments. The virus stunts the growth of orchids both through size reduction as well as lowering flower yield. CymMV has also been linked to cases of breakage in flower coloration as well as blossom necrosis. This is especially important because this causes the commercial value of the plants to be greatly reduced. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cymbidium mosaic virus」の詳細全文を読む スポンサード リンク
