| This study was conducted to investigate the occurrence and characterization of tobacco mosaic virus(TMV) in Chinese foxglove isolated from the field of the Chonbuk province(Jinan, Jangsu, Jeongeup). TMV was detected in all three regions and confirmed positive reaction by ELISA test. In the host range test, Chenopodium amaranticola, Nicotiana glutinosa, N. tabacum cv. 'Bright yellow', N. tabacum cv. 'KY¡©57, Datura stramonium were locally infected with the virus. The virus produced mosaic symptom on inoculated leaves of N. tabacum cv. 'Samson'. However, Chenopodium quinoa, Glycine max, Raphanus sativus, Cucumis sativus, Cucurbita moschata, Brassica rape and Lycopersion esculentum did not show any symptoms. TMV particles were revealed as a stiff rod shape by transmission electron microscopic(TEM) and measured as 300 nm in length with 18 nm in diameter. Total RNA was extracted from showing symptom loaves infected with TMV and the reverse transcription¡©polymerase chain reaction (RT¡©PCR) obtained 531 bp DNA product of RNA with specific primer used. The capsid protein of TMV¡©RE showed higher amino acid sequence homology(97.7£¥) with TMV¡©To than with TMV¡©P(72.2£¥). The capsid protein of TMV¡©152 showed same amino acid sequence homology with TMV¡©F. The result of comparison of nucleotides sequence homology between TMV¡©RE strain and other TMV strain showed 94£¥ homology with others except TMV¡©P(67.3£¥) and TMV ¡© C(68.6£¥). |
