摘要
本研究调查了从韩国六个沿海地区采集的褐色海藻马尾藻中分离出的内生真菌的多样性：江陵、浦项、扶安、泰安、统营和丽水。通过 ITS rDNA 序列分析，共分离出 154 株真菌，分为 43 个属 84 个种。根据香农指数评估，物种多样性以统营（H'=3.273）最高，其次是浦项（H'=3.209）、普安（H'=2.691）、丽水（H'=2.649）、江陵（H'=2.342）和泰安（H'=2.025）。主坐标分析（PCoA）显示，水温和溶解氧是影响真菌群落结构区域差异的主要环境因素。这项研究强调了环境条件在影响苏门答腊内生真菌的多样性和群落组成方面的重要作用。
Diversity and Community Structure of Endophytic Fungi Isolated from the Brown Seaweed Sargassum thunbergii in Coastal Regions of Korea.
This study investigated the diversity of endophytic fungi isolated from the brown seaweed, Sargassum thunbergia, collected from six coastal regions in Korea: Gangneung, Pohang, Buan, Taean, Tongyeong and Yeosu. A total of 154 fungal strains were isolated using ITS rDNA sequence analysis, resulting in 84 species across 43 genera. Species diversity, assessed based on the Shannon index, was highest in Tongyeong (H'=3.273), followed by Pohang (H'=3.209), Buan (H'=2.691), Yeosu (H'=2.649), Gangneung (H'=2.342), and Taean (H'=2.025). Principal Coordinates Analysis (PCoA) revealed that water temperature and dissolved oxygen are the primary environmental factors influencing the regional variation in fungal community structure. This study underscores the significance of environmental conditions in shaping the diversity and community composition of endophytic fungi in S. thunbergii.
期刊介绍：
Mycobiology is an international journal devoted to the publication of fundamental and applied investigations on all aspects of mycology and their traditional allies. It is published quarterly and is the official publication of the Korean Society of Mycology. Mycobiology publishes reports of basic research on fungi and fungus-like organisms, including yeasts, filamentous fungi, lichen fungi, oomycetes, moulds, and mushroom. Topics also include molecular and cellular biology, biochemistry, metabolism, developmental biology, environmental mycology, evolution, ecology, taxonomy and systematics, genetics/genomics, fungal pathogen and disease control, physiology, and industrial biotechnology using fungi.
