초록

국내 석회암지대에 서식하는 참나무류의 뿌리에서 외생균근균(ectomycorrhizal fungi, ECM)의 다양성을 분석하였다. 분자분석을 통해 참나무류에 공생하고 있는 45속의 ECM을 확인하였다. ECM의 종 다양성 지수는 pH, 칼슘 농도, 유효인산 농도가 증가할수록 감소하는 경향을 보였고, 전질소 함량과 유기물 함량이 증가할수록 증가하는 경향을 보였다. 군집분석 결과 석회토양의 특징인 pH와 칼슘 농도와 양의 상관관계를 갖는 ECM은 Sebacina, Tomentella, Tuber, Densospora, Inocybe, Suillus, Piloderma속에 속하는 균주들 이였으며, 이들은 토양 안정성이 약화된 석회암지대의 생태복원에 활용될 수 있을 것으로 판단된다.

In this study, we analyzed the diversity of ectomycorrhizal (ECM) fungal communities of Quercus spp. roots in the limestone area. We identified 45 generd of ECM using next generation sequencing (NGS) analysis. Soil chemical composition analysis confirmed soil pH, substitution calcium concentration, total nitrogen content, organic phosphate, and organic matter content. Shannon's Index was calculated according to the changes in soil chemical composition. The results of cluster analysis showed that Sebacina, Tomentella, Tuber, Densospora, Inocybe, Suillus, and Piloderma were the main genera of symbiotic ECM fungi that thrived in soil with high pH and calcium content.
