Abstract

Four fungal species, during indoor air monitoring for fungi that possibly affect the field testing of a newly bred shiitake cultivar in cultivation houses located in Cheongyang, Chungnam Province and Jangheung, Jeonnam Province. Of these species, two are known to be plant pathogens and the other two are saprobes but potent contaminators in the mushroom cultivation environment. This study reports the morphological characteristics and phylogenetic relationships of these four species based on nucleotide sequences of the internal transcribed spacer (ITS) and 18S rDNA region, including their known information.

청양과 장흥에 소재한 버섯 재배사에서 새로 육종된 표고 품종의 현장 실증검증 도중 문제를 일으킬 수 있는 잠재적 진균을 파악하고자 재배사내 공기 모니터링을 수행하여 오던 중 국내에 기록이 없는 Mortierella parvispora, Doratomyces purpureofuscus, Periconia byssoides, Periconia pseudobyssoides 등 네 종의 진균을 분리하여 동정하였다. 이중 두 종은 식물병원균으로 알려진 종이었고 다른 두 종은 부생성 균으로 다량의 포자를 생산하고 버섯재배 환경에서 오염균으로 작용할 가능성이 있는 균이었다. 본 연구에서는 이들 동정된 진균에 대한 형태적 특성, internal transcribed spacer (ITS) 와 18S rDNA region 염기서열 분석에 기반한 계통학적 관계, 그리고 알려진 정보 등에 대하여 보고하고자 한다.
