초록

2016년 충북 충주에서 모자이크 병징을 보이는 초석잠을 채집하였다. 담배와 명아주에 즙액접종을 실시한 결과 담배에서 접종엽에 괴사반점이 나타나고 명아주 2종에서 상엽에 퇴록반점을 동반한 모자이크 병징이 관찰되었다. 기주반응과 결과를 통해 여러 바이러스의 복합감염을 추정할 수 있었고, 추정되는 바이러스의 확인을 위해 속특이 및 종특이 프라이머를 이용하여 RT-PCR을 수행하여 3종의 바이러스(AMV, CMV, TMV)를 검정하였다. 본 연구는 국내 초석잠에서 3종의 바이러스 감염을 확인하였고 CMV의 감염에 대한 첫 보고이다.

Chinese artichoke (Stachys sieboldii Miq.) belongs to herbaceous perennial plants of Labiatea and is cultivated as edible and medicinal crops in China, Japan and Korea. A Chinese artichoke plant showing virus-like symptoms was collected in Chungju, Korea. Plant sap of the sample was inoculated in Nicotiana tabacum cv. Xanthi-nc, Chenopodium quinoa and Chenopodium amaranticolor. Necrotic local lesions were observed in the inoculated leaves of N. tabacum cv. Xanthi-nc and C. amaranticolor, C. quinoa with systemic chlorotic spots and mosaic symptoms on the upper leaves. The disease reactions on indicator plants suggested that the collected Chinese artichoke sample was mixed-infected with different viruses. We detected three viruses by RT-PCR analysis using genus- and species-specific primer sets for Alfalfa mosaic virus (AMV), Cucumber mosaic virus (CMV) and Tobacco mosaic virus (TMV). This study is the first report of a mixed infection of three viruses in Chinese artichoke in Korea.
