Abstract Cold seeps in the deep sea are closely linked to energy exploration as well as global climate change. The alkane-dominated chemical energy-driven model makes cold seeps an oasis of deep-sea life, showcasing an unparalleled reservoir of microbial genetic diversity. By analyzing 113 metagenomes collected from 14 global sites across 5 cold seep types, we present a comprehensive Cold Seep Microbiomic Database (CSMD) to archive the genomic and functional diversity of cold seep microbiome. The CSMD included over 49 million non-redundant genes and 3175 metagenome-assembled genomes (MAGs), which represented 1895 species spanning 105 phyla. In addition, beta diversity analysis indicated that both the sampling site and cold seep type had a substantial impact on the prokaryotic microbiome community composition. Heterotrophic and anaerobic metabolisms were prevalent in microbial communities, accompanied by considerable mixotrophs and facultative anaerobes, highlighting the versatile metabolic potential in cold seeps. Furthermore, secondary metabolic gene cluster analysis indicated that at least 98.81% of the sequences potentially encoded novel natural products, with ribosomal processing peptides being the predominant type widely distributed in archaea and bacteria. Overall, the CSMD represents a valuable resource that would enhance the understanding and utilization of global cold seep microbiomes.
全球海洋冷渗漏元基因组揭示了分类、代谢功能和天然产品的多样性
摘要 深海冷渗漏与能源开发和全球气候变化密切相关。以烷烃为主的化学能驱动模式使冷渗漏成为深海生命的绿洲,展示了无与伦比的微生物遗传多样性宝库。通过分析从全球 5 种冷渗漏类型的 14 个地点收集到的 113 个元基因组,我们建立了一个全面的冷渗漏微生物组数据库(CSMD),以归档冷渗漏微生物组的基因组和功能多样性。该数据库包括超过 4,900 万个非冗余基因和 3175 个元基因组组装基因组(MAGs),代表了跨越 105 个门的 1895 个物种。此外,β 多样性分析表明,采样地点和冷渗漏类型对原核微生物群落组成有很大影响。微生物群落中普遍存在异养代谢和厌氧代谢,同时还有相当多的混养菌和兼性厌氧菌,这凸显了冷渗漏中多种多样的代谢潜力。此外,次生代谢基因聚类分析表明,至少有 98.81% 的序列可能编码新型天然产物,其中核糖体加工肽是最主要的类型,广泛分布于古细菌和细菌中。总之,CSMD 是一种宝贵的资源,可增进对全球冷渗漏微生物群的了解和利用。
