Abstract
생강나무에 공생하는 내생균의 다양성을 확인하기 위하여, 강원도 4 개 지역에서 병증이 없는 생강나무 잎을 채집하여 내생균을 분리하였다. 분리된 내생균의 rDNA의 ITS지역을 분석한 결과, Alternaria alternata, Annulohypoxylon annulatum, Creosphaeria sassafras, Diaporthe eres, Discosia sp., Epicoccum nigrum, Glomerella acutata, Glomerella cingulata, Paraconiothyrium brasiliense, Pestalotiopsis neglecta, Phomopsis amygdali, Xylaria sp.의 총 7과 11속 12종이 확인되었으며 Phomopsis amygdali가 모든 연구 지역의 생강나무 잎에서 가장 높은 빈도로 분리되었으며 채집지에 따라 내생균의 종 다양성에 차이가 있음을 확인하였다. Leaves of Lindera obtusiloba were collected from four sites in Gangwon Province, Korea. Endophytic fungi were isolated from the leaves and identified using ITS sequences of rDNA. Total twelve species belonging of endophytic fungi were identified; Alternaria alternata, Annulohypoxylon annulatum, Creosphaeria sassafras, Diaporthe eres, Discosia sp., Epicoccum nigrum, Glomerella acutata, Glomerella cingulata, Paraconiothyrium brasiliense, Pestalotiopsis neglecta, Phomopsis amygdali, Xylaria sp. The endophytic fungus, Phomopsis amygdali, was the most dominant species isolated from L. obtusiloba in this study and the fungal diversities varied in the different sites.
