Abstract

Marine biofilms were newly revealed as a giant microbial diversity pool for global oceans. However, the cyanobacterial diversity in marine biofilms within the upper seawater column and its ecological and evolutionary implications remains undetermined. Here, we reconstructed a full picture of modern marine cyanobacteria habitats by re-analyzing 9.3 terabyte metagenomic data sets and 2,648 metagenome-assembled genomes (MAGs). The abundances of cyanobacteria lineages exclusively detected in marine biofilms were up to ninefold higher than those in seawater at similar sample size. Analyses revealed that cyanobacteria in marine biofilms are specialists with strong geographical and environmental constraints on their genome and functional adaption, which is in stark contrast to the generalistic features of seawater-derived cyanobacteria. Molecular dating suggests that the important diversifications in biofilm-forming cyanobacteria appear to coincide with the Great Oxidation Event (GOE), "boring billion" middle Proterozoic, and the Neoproterozoic Oxidation Event (NOE). These new insights suggest that marine biofilms are large and important cyanobacterial factories for the global oceans.

Importance: Cyanobacteria, highly diverse microbial organisms, play a crucial role in Earth's oxygenation and biogeochemical cycling. However, their connection to these processes remains unclear, partly due to incomplete surveys of oceanic niches. Our study uncovered significant cyanobacterial diversity in marine biofilms, showing distinct niche differentiation compared to seawater counterparts. These patterns reflect three key stages of marine cyanobacterial diversification, coinciding with major geological events in the Earth's history.

海洋生物薄膜:全球海洋的蓝藻工厂。
新近发现的海洋生物薄膜是全球海洋中巨大的微生物多样性库。然而,海水上层生物膜中的蓝藻多样性及其对生态和进化的影响仍未确定。在此,我们通过重新分析 9.3 TB 的元基因组数据集和 2,648 个元基因组组装基因组(MAGs),重建了现代海洋蓝藻栖息地的全貌。在样本量相近的情况下,海洋生物薄膜中专门检测到的蓝藻菌系的丰度比海水中的高出九倍之多。分析表明,海洋生物膜中的蓝藻是专科蓝藻,其基因组和功能适应性受到地理和环境的强烈限制,这与海水蓝藻的普遍性特征形成了鲜明对比。分子年代测定表明,形成生物膜的蓝藻的重要分化似乎与大氧化事件(GOE)、"无聊的十亿 "中新生代和新新生代氧化事件(NOE)相吻合。这些新发现表明,海洋生物薄膜是全球海洋中重要的大型蓝藻工厂:蓝藻是高度多样化的微生物有机体,在地球的氧合和生物地球化学循环中发挥着至关重要的作用。然而,它们与这些过程之间的联系仍不清楚,部分原因是对海洋生态位的调查不全面。我们的研究发现了海洋生物膜中蓝藻的显著多样性,与海水中的蓝藻相比,蓝藻表现出明显的生态位分化。这些模式反映了海洋蓝藻多样化的三个关键阶段,与地球历史上的重大地质事件相吻合。
