Abstract

Three fungal isolates, NNIBRFG108, 1139, and 1480, were isolated from freshwater environments; NNIBRFG108 from plant litter in Samcheok, Gangwon and NNIBRFG1139 and 1480 from the soil in Jeju & Gimcheon, Gyeongbuk, Korea. Based on the morphological characteristics and phylogenetic analysis of internal tanscribed spacer (ITS), 28S rDNA region, and ${\beta}$-tubulin gene, NNIBRFG108, NNIBRFG1139, and NNIBRFG1480 isolates were confirmed as Didymella segeticola, D. ellipsoidea, and D. aeria, respectively. Neither species has previously been described in Korea.

국내에 보고되지 않은 3종의 균류가 담수환경으로 부터 분리되었다. NNIBRFG108은 강원도 삼척의 담수침전식물체에서 분리되었고, NNIBRFG1139와 NNIBRFG1480은 경북 김천과 제주지역의 토양으로부터 분리되었다. 형태적 특징 및 internal transcribed spacers (ITS), 18S rDNA, 28S rDNA 및 ${\beta}$-tubulin 유전자를 이용한 분자계통학적 분류를 통해 동정한 결과, NNIBRFG108, NNIBRFG1139, NNIBRFG1480 균주는 각각 Didymella segeticola, D. ellipsoidea 및 D. aeria으로 확인되었다. 이는 국내에서는 발견되지 않은 미기록종으로 본 보고가 국내 최초이다.
