珊瑚拥有多种多样的共生微生物，在宿主营养，繁殖和发育中发挥着关键作用。海洋环境的变化，例如夜间人工光照射的增加，可能会改变这些关系，导致珊瑚健康状况下降。在这项研究中，我们研究了与造礁珊瑚鹿角珊瑚（Acropora digitifera）妊娠标本相关的微生物组。我们还评估了ALAN对珊瑚相关微生物群落的时间效应，使用16S rRNA基因V4高变区的高通量测序。助理指状体微生物群落以变形菌门、厚壁菌门和拟杆菌门为主。暴露于ALAN对珊瑚微生物组没有大规模的影响，尽管隶属于杜鹃花科、柄杆菌科、伯克霍尔德氏菌科、毛螺菌科和瘤胃球菌科的类群在受到ALAN的珊瑚中显著富集。我们进一步注意到，无论光照处理如何，随着产卵期的临近，内寄生单胞菌科（内寄生单胞菌属）的相对丰度增加。这些发现突出了A.的digitifera微生物群落短期人工光污染下，并提供了初步的见解集体holobiont ALAN的反应。
Corals harbor a great diversity of symbiotic microorganisms that play pivotal roles in host nutrition, reproduction, and development. Changes in the ocean environment, such as increasing exposure to artificial light at night (ALAN), may alter these relationships and result in a decline in coral health. In this study, we examined the microbiome associated with gravid specimens of the reef-building coral Acropora digitifera. We also assessed the temporal effects of ALAN on the coral-associated microbial community using high-throughput sequencing of the 16S rRNA gene V4 hypervariable region. The A. digitifera microbial community was dominated by phyla Proteobacteria, Firmicutes, and Bacteroidetes. Exposure to ALAN had no large-scale effect on the coral microbiome, although taxa affiliated with Rhodobacteraceae, Caulobacteraceae, Burkholderiaceae, Lachnospiraceae, and Ruminococcaceae were significantly enriched in corals subjected to ALAN. We further noted an increase in the relative abundance of the family Endozoicomonadaceae (Endozoicomonas) as the spawning period approached, regardless of light treatment. These findings highlight the stability of the A. digitifera microbial community under short-term artificial light pollution and provide initial insights into the response of the collective holobiont to ALAN.
