Over 300 fungal species were isolated from unique deep-sea environments, including methane cold seeps, 10,000m deep-sea trench, and whale fall sites in this study. Also, many novel unknown fungal groups were revealed in deep-sea environments by analyzing fungal diversity with single cell genomics and next generation sequencer. It was suggested that the group frequently detected from methane cold seep was highly novel and an early diverged group. This study led us to understand fungal diversity and its role in deep-sea environments, through isolating many new and previously unknown species, detecting unknown fungal groups, and using expressed sequence tag (EST) analysis of fungi reported only from deep-sea environments.

在这项研究中，从独特的深海环境中分离出300多种真菌，包括甲烷冷泉，10，000米深海海沟和鲸鱼坠落地点。同时，通过单细胞基因组学和下一代测序技术分析深海环境中的真菌多样性，发现了许多新的未知真菌类群。这表明，在甲烷冷泉中频繁发现的这一类群是一个高度新的、较早分化的类群。这项研究使我们了解真菌的多样性及其在深海环境中的作用，通过分离许多新的和以前未知的物种，检测未知的真菌群，并使用表达序列标签（EST）分析仅从深海环境中报道的真菌。
