摘要
海草莠群有助于海洋生态系统的保护，减少全球变暖的影响并控制病原体。然而，由于环境负荷导致海草栖息地的减少，已成为紧急的全球性问题。一个解决方法是更好地理解健康的海草栖息地。我们估计了日本八个沿海地区沉积物中共生和代谢系统的结构特征，每个地区都包含海草覆盖区域和相邻的无植被区域。值得注意的是，海草通常维持一种平衡的共生关系，表现为与 cable 细菌 (Desulfobulbaceae)、氮循环细菌 (Hyphomonadaceae) 和珊瑚藻 (Corallinophycidae) 的正相关，以及与钟鼓藻 (Diatomea) 的负相关。此外，海草生长条件通过激活氮相关代谢途径而抑制甲烷生成。我们的发现突显了海洋植物及其共生系统在蓝碳储存的环境梯度背景下确保环境保护的关键作用。
