| 摘要: |
| 海草是海洋中唯一的一类沉水被子植物, 构成了生物多样性丰富、生态服务价值极高的海草床。海草与其相关微生物群体共同组成复杂的共生体, 在营养循环、海草健康发育和生产力维持等方面发挥重要作用。本文综述了海草微生物组在不同部位的多样性特征, 探讨了海草代谢产物调控微生物群落结构的机制, 并分析了环境因素对微生物群落的再塑造作用, 剖析了海草共生体在氮磷循环、硫化物解毒、病害防御和植物激素分泌调节等方面的可能作用和影响。目的为海草床的保护修复寻找科学依据, 理解其在缓解气候变化和提升海洋生态系统服务中的重要意义。 |

| Abstract: |
| Seagrasses, an exclusive class of angiosperms submerged in marine environments, form seagrass beds that exhibit remarkable biodiversity and possess substantial ecological service value. Seagrasses, along with their associated microbial communities, establish intricate symbiotic entities that play a crucial role in nutrient cycling and contribute to the robust development and sustained productivity of seagrasses. This review provides a comprehensive summary of the diversity characteristics of seagrass microbiomes across various tissues, elucidates the mechanisms by which seagrass metabolic products regulate the microbial community structure, and analyzes how environmental factors reshape these microbial communities. In addition, this review explores the potential role and impact of seagrass symbiosis on nitrogen and phosphorus cycling, sulfide detoxification, disease defense, and the regulation of plant hormone secretion. This study provides scientific evidence for the conservation and restoration of seagrass beds and an understanding of their importance in mitigating climate change and enhancing marine ecosystem services. |
