초록

작약에서 분리된 Cylindrocarpon destructans KACC44663 균주의 인삼에 대한 병원성 여부를 밝혀내고자 병원성 검정을 실시하였고 새로운 분류체계에 따른 균의 재분류를 위해 계통학적 유연관계를 분석하였다. 작약으로부터 분리된 KACC44663 균주가 인삼에 병을 일으키는 것을 확인하였고, 새로운 분류체계에 의해 I. radicicola species complex 내 위치하는 Ilyonectria robusta로 동정하였다. 이는 국내에서 타 기주로부터 분리된 병원균이 인삼에 뿌리썩음병을 일으키는 것을 증명한 첫 사례이다.

To obtain useful data on root rot in Korean ginseng, we performed phylogenetic analysis and pathogenicity test for Cylindrocarpon destructans isolated from peony. Cylindrocarpon destructans isolates from peony were proven to cause ginseng root rot. The isolate KACC44663 was identified as Ilyonectria robusta under the new classification system, which belongs to the I. radicicola species complex. This is the first report of the pathogenic isolate, which was isolated from another host plant, but not ginseng, that can cause root rot disease on ginseng in Korea.
