AI总结：
本研究通过重新分析49项沿海调查数据并结合结构方程建模与线性非高斯无环模型，识别出促进Zostera marina生长、降低病原风险的关键共生细菌组合。
摘要：
海草床在蓝碳和水生生态系统服务中发挥着重要作用。然而，促进海草繁茂生长的方法仍在探索之中。本研究重新验证了来自49项公共沿海调查的数据，这些调查涉及近岸水产养殖设施周围海草和海藻的分布，并发现了一个海草Zostera marina繁茂生长的特殊区域。那里的细菌种群显示，属于黄杆菌目（Flavobacteriales）的候选病原体明显减少。此外，基于机器学习数据的结构方程建模和线性非高斯无环模型估算出一个有利于海草生长的最佳共生细菌类群候选组合如下：作为肠道寄居细菌的毛螺菌科（Lachnospiraceae）和瘤胃球菌科（Ruminococcaceae），作为光合细菌的红杆菌科（Rhodobacteraceae），以及作为电缆细菌、调节氧气或硝酸盐还原与硫化物氧化的脱硫球茎菌科（Desulfobulbaceae）。这些观察结果为认识对水产养殖中蓝碳和低病原海洋生态系统至关重要的海草共生细菌结构提供了新视角。
英文摘要：
Seagrass meadows play an essential role in blue carbon and aquatic ecosystem services. However, methods for the flourishing of seagrass are still being explored. Here, data from 49 public coastal surveys on the distribution of seagrass and seaweed around the onshore aquaculture facilities are revalidated, and an exceptional area where the seagrass Zostera marina thrives was found. The bacterial population there showed an apparent decrease in the pathogen candidates belonging to the order Flavobacteriales. Moreover, structure equation modeling and a linear non-Gaussian acyclic model based on the machine learning data estimated an optimal symbiotic bacterial group candidate for seagrass growth as follows: the Lachnospiraceae and Ruminococcaceae families as gut-inhabitant bacteria, Rhodobacteraceae as photosynthetic bacteria, and Desulfobulbaceae as cable bacteria modulating oxygen or nitrate reduction and oxidation of sulfide. These observations confer a novel perspective on the seagrass symbiotic bacterial structures critical for blue carbon and low-pathogenic marine ecosystems in aquaculture.
