造礁珊瑚居住着功能多样的微生物，这些微生物在人类世的珊瑚健康和持久性中起着重要作用。然而，我们对珊瑚全息生物内部复杂关联的理解在很大程度上是有限的，特别是跨代暴露于环境压力下，如海洋酸化。本研究采用扩增子测序和分析方法，研究了一种具有重要生态意义的珊瑚poillopora damicornis在跨代暴露于中高CO2（CO2分压）水平后的微生物组发育情况。结果表明，共生菌科成虫和幼虫的群落结构具有相似的格局，均以durusdiniumspp为主。相反，原核生物群落在成虫和幼虫之间存在差异，这可能是受寄主发育的影响。令人惊讶的是，在不同的co2处理下，共生菌科和原核生物群落都没有显著的变化，这与生活史阶段无关。本研究表明，海洋酸化对p的影响不显著。珊瑚群落是否存在跨代适应，以预测未来气候变化，值得进一步研究。
Reef-building corals are inhabited by functionally diverse microorganisms which play important roles in coral health and persistence in the Anthropocene. However, our understanding of the complex associations within coral holobionts is largely limited, particularly transgenerational exposure to environmental stress, like ocean acidification. Here we investigated the microbiome development of an ecologically important coralPocillopora damicornisfollowing transgenerational exposure to moderate and highpCO2(partial pressure of CO2) levels, using amplicon sequencing and analysis. Our results showed that the Symbiodiniaceae community structures in adult and juvenile had similar patterns, all of which were dominated byDurusdiniumspp., previously known as clade D. Conversely, prokaryotic communities varied between adults and juveniles, possibly driven by the effect of host development. Surprisingly, there were no significant changes in both Symbiodiniaceae and prokaryotic communities with differentpCO2treatments, which was independent of the life history stage. This study shows that ocean acidification has no significant effect onP. damicornismicrobiome, and warrants further research to test whether transgenerational acclimation exists in coral holobiont to projected future climate change.
