真菌是生态系统中最重要的组成部分之一，它们凭借其高度通用的生理功能占据了各种各样的环境。最近，人们开始认识到在极端环境之一——深海中存在真菌。本文介绍了通过调查从多个深海环境（包括水深 10,000 米和甲烷冷泉地点）收集的深海沉积物中的真菌多样性而获得的最新科学发现。 PCR介导的分析揭示了多种高度新颖的真菌系统型的存在，包括位于壶菌门和Rozella spp的深分支中的新分类群。作为最接近的相关生物，这可能为真菌的早期进化提供重要的见解。
Fungi are one of the most important components in ecosystems and they occupy a wide variety of environments by virtue of their highly versatile physiology function. Recently, the presence of fungi in one of the extreme environments, deep-sea, has started to be recognized. In this article, recent scientific findings through the investigation of fungal diversity in deep-sea sediments collected from several deep-sea environments, including water depths of 10,000 m and methane cold-seep sites were described. PCR-mediated analysis revealed the presence of diverse highly novel fungal phylotypes, including new taxonomic groups placed in deep branches within the phylum of Chytridiomycota with Rozella spp. as the closest related organisms, which may provide key insights into the early evolution of fungi.
