Genomes of Symbiodiniaceae-associated vibrios

We generated and analyzed 11 Vibrio genomes isolated from Symbiodiniaceae-enriched fractions of Acropora nobilis to investigate their potential roles in coral holobiont function. Despite known virulence potential, these Vibrio strains were consistently associated with Symbiodiniaceae and carried genes linked to beneficial traits such as vitamin biosynthesis and antioxidant production. Their persistent presence and genomic features suggest potential mutualistic interactions rather than strictly pathogenic roles. This genomic resource enables a reassessment of Vibrio’s ecological roles and opens new directions for understanding microbial contributions to coral resilience.本研究组装并分析了11株从雅致鹿角珊瑚（Acropora nobilis）的虫黄藻科（Symbiodiniaceae）富集组分中分离得到的弧菌（Vibrio）基因组，以探究其在珊瑚共生体（holobiont）功能中的潜在作用。尽管已知这些弧菌菌株具备潜在致病性，但它们始终与虫黄藻科共生，且携带与维生素生物合成、抗氧化产物生成等有益性状相关的基因。其持续定植的特性与基因组特征表明，这些弧菌可能与宿主存在互利共生的相互作用，而非单纯的致病角色。本基因组数据集为重新评估弧菌的生态功能提供了重要支撑，也为解析微生物对珊瑚抗逆性的贡献开辟了全新方向。
