Abstract

Abstract Coral reefs are one of the most biodiverse marine ecosystems. Diverse microbes are associated with corals, including zooxanthellae, protists, prokaryotes, and viruses. This study aimed to investigate the genetic diversity of the culturable fungi associated with scleractinian corals in the Gulf of Thailand. Ribosomal DNA sequence analysis and morphological analysis of 130 fungal isolates revealed a high diversity of fungal phylotypes from three coral species: Pavona decussata, Pocillopora damicornis and Porites lutea. Ascomycota was the most abundant fungal phylum. The predominant orders included Eurotiales, Cladosporiales, Hypocreales, Mycosphaerellales, and Diaporthales. There were eight orders of the Basidiomycota dominated by Polyporales, Hymenochaetales, Agaricales, and Wallemiales. A principal component analysis was performed to compare abundance and correlation between the fungal communities, sampling locations and coral species. The results showed that the dissimilarity of fungal communities corresponded to geographic localities. On the other hand, there was a considerable overlap between the fungal communities of different coral species. The results from this research provide information on the diversity and ecology of the fungal communities associated with scleractinian corals in the Gulf of Thailand.

泰国湾与硬核珊瑚相关的可培养真菌遗传多样性

珊瑚礁是最具生物多样性的海洋生态系统之一。珊瑚有多种微生物，包括虫黄藻、原生生物、原核生物和病毒。本研究旨在研究泰国湾核状珊瑚相关可培养真菌的遗传多样性。对130株真菌的核糖体DNA序列分析和形态分析表明，3种珊瑚(Pavona decussata、Pocillopora damicornis和Porites lutea)的真菌种型具有高度的多样性。子囊菌门是最丰富的真菌门。主要目有Eurotiales、Cladosporiales、Hypocreales、Mycosphaerellales和Diaporthales。担子菌纲有8目，以Polyporales、hymenochaeales、Agaricales和walllemiales为主。主成分分析比较了真菌群落、采样地点和珊瑚种类之间的丰度和相关性。结果表明，真菌群落的差异与地理位置相对应。另一方面，不同珊瑚物种的真菌群落之间有相当大的重叠。本研究的结果为泰国湾核状珊瑚真菌群落的多样性和生态学提供了信息。
