초록
모과나무 가지의 일부에서 이상 증상이 있는 부위로부터 균을 순수분리하여 균류에 대한 형태적 특성과 더불어 ${\beta}$-tubulin 유전자 염기서열에 기반한 계통학적 분석을 수행하였다. 동정된 균은 점균류에 속하는 Stemonaria longa로 확인되었으며 국내 미기록 종임을 확인하였다.
Chaenomeles sinensis, called as Chinese quince, belongs to the family Rosaceae and is widely distributed in Korea, China, and Japan. A microorganism was isolated from part of a twig of C. sinensis that showed an abnormal appearance. The microorganism was identified as the slime mold Stemonaria longa of the division Myxomycota, which was previously unrecorded in Korea. The present study reports the morphological characteristics of the isolated fungus and a phylogenetic relationship based on the ${\beta}$-tubulin gene sequences.
