Abstract

Seaweed-associated endophytic fungi have recently attracted considerable attention due to their ecological significance and potential application as biological resources. Accordingly, research efforts to isolate and characterize fungal endophytes from marine macroalgae have accelerated. This study aimed to isolate and identify endophytic fungi from two brown algae, Sargassum thunbergii and S. muticum, collected from intertidal zones in Tongyeong and Pohang, Korea. Identification was performed based on morphological characteristics and multilocus phylogenetic analyses using ITS, LSU, TEF1, TUB2, and RPB2 gene sequences. As a result, three previously unrecorded fungal species in Korea were identified: Neopyrenochaeta telephoni, Trichoderma cyanodichotomum, and Microascus intricatus. This study provides detailed descriptions of their morphological features and phylogenetic relationships. These findings contribute to a better understanding of fungal diversity associated with brown algae in Korea and highlight the potential significance of endophytic fungi in marine ecosystems.

韩国褐藻内生真菌的形态和系统发育特征。
近年来,海藻相关内生真菌因其生态意义和潜在的生物资源应用而备受关注。因此,从海洋大型藻类中分离和表征真菌内生菌的研究工作加快了。本研究旨在从韩国统营和浦项潮间带的两种褐藻中分离和鉴定内生真菌,即马尾藻(Sargassum thunbergii)和muticum。利用ITS、LSU、TEF1、TUB2和RPB2基因序列进行形态学鉴定和多位点系统发育分析。结果,在韩国鉴定了三种以前未记录的真菌物种:Neopyrenochaeta telephoni, cyanodihotomum木霉和Microascus intricatus。本研究详细描述了它们的形态特征和系统发育关系。这些发现有助于更好地了解与韩国褐藻相关的真菌多样性,并突出了内生真菌在海洋生态系统中的潜在意义。

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.
