Celery mosaic virus (CeMV) is a plant pathogenic virus 〔(About Plant Viruses ) 〕 in the genus'' Potyvirus '' and the virus family '' Potyviridae ''. In California (USA), mosaic diseases of celery (''Apium graveolens'') were reported as early as 1922.〔Poole, R.F. 1922. Celery mosaic. Phytopthology 12:151-154.〕 In time, it became clear that there were at least two different viruses causing mosaic diseases with similar symptoms in celery. These two viruses were first differentiated by host range.〔Severin, H.H.P. and Freitag, J.H. 1938. Western celery mosaic. Hilgardia 11:493-558.〕 One of the viruses had a wide host range and was named ''Southern celery mosaic''. The second had a host range restricted to the family Umbelliferae (Apiaceae) and was called ''Western celery mosaic''. Continued research showed that the ''Southern mosaic virus'' was actually an isolate of ''Cucumber mosaic virus'' 〔Price, W.C. 1935. Classification of southern celery mosaic virus. Phytopathology. 25:947-954.〕 and '' Western celery mosaic'' eventually became known simply as ''Celery mosaic virus''. ==Symptoms and host range== Celery is the most common host of this virus. As the name implies, this virus causes a mosaic or mottling in the leaves of celery. There can also be malformation of leaflets. In older leaves, chorotic/necrotic spots may occur and the plants can be stunted. (see symptoms description〔http://www.ipm.ucdavis.edu/PMG/r104100711.html#SYMPTOMS〕) ( Viral Inclusions of Celery mosaic virus. ) In addition to celery, this virus has been identified in other important crops in the '' Apiaceae '' including carrots (''Daucus carota''), coriander (''Coriandrum sativum''), parsley (''Petroselinum crispum''), parsnip (''Pastinaca sativa''), and dill (''Anethum graveolens''). It has also been identified in several weed species in the ''Apiaceae'' family, including poison hemlock (''Conium maculatum''),〔Sutabutra, T. and Campbell, R.N. 1971. Pl. Dis. Reptr. 55:328-332.〕 mock bishopweed (''Ptilimnium capillaceum'') and wild cherry (''Apium leptophyllum'').〔http://www.ipmcenters.org/cropprofiles/docs/FLCelery.html〕 There is some confusion in the literature as to whether CeMV can infect hosts in the family ''Chenopodiaceae''. In 2002, a paper reporting the results of a survey in Australia found three different but related potyviruses infecting species of the ''Apiaceae'' in Australia, CeMV, ''Carrot virus Y'' (CarVY), and '' Apium virus Y '' (ApVY).〔Moran J. et al. 2002. Arch. Virol. 147:1855-1867.〕 Both CarVY〔Latham, L.J. and Jones R.A. 2004. Virus Research 100 :89-99.〕 and ApVY have been shown to infect one or more species of ''Chenopodium''. The latter reference, reporting ApVY infecting celery in New Zealand, found the plants to be doubly infected with CeMV and ApVY and the authors suggested that CeMV “may mask the presence of ApVY”. It is possible that one or both of these viruses have been undetected in mixed infections with CeMV in some of the past studies. With sequence data now available for both CarVY and ApVY this ambiguity may be cleared up in time. 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「Celery mosaic virus」の詳細全文を読む スポンサード リンク
