从浅水到深海，珊瑚构成了具有重要生态和经济价值的不同群落的基础。这些社区面临许多人为压力，包括能源和矿物开采活动、海洋酸化和海洋温度上升。珊瑚和它们的共生体产生多种化合物，可能有助于提供对这些压力源的恢复能力。目的通过研究跨空间和系统发育的模式，研究生态背景下深海珊瑚的代谢组学多样性。方法采用非靶向液相色谱-质谱联用技术对墨西哥湾北部三个地点的Callogorgia三角洲深海珊瑚以及另外三种深海珊瑚Stichopathessp的代谢组学多样性进行了研究。还有一种浅水种，掌角鹿角。结果不同珊瑚种类具有不同的代谢组指纹图谱和代谢组丰富度，包括每种珊瑚特有的核心离子。三角洲的多样性最少，百日花的多样性最多。不同位点的三角洲在个体和种群水平上具有不同的代谢组指纹图谱和代谢组丰富度，但没有位点表现出独特的核心离子。c特有的两个核离子。delta被认为是二萜，因此可能具有重要的生物学功能。结论深海珊瑚具有明显的代谢组指纹图谱，并在多个尺度上表现出较高的代谢组多样性，这可能有助于它们对自然和人为压力源（包括气候变化）的响应能力。
IntroductionFrom shallow water to the deep sea, corals form the basis of diverse communities with significant ecological and economic value. These communities face many anthropogenic stressors including energy and mineral extraction activities, ocean acidification and rising sea temperatures. Corals and their symbionts produce a diverse assemblage of compounds that may help provide resilience to some of these stressors.ObjectivesWe aim to characterize the metabolomic diversity of deep-sea corals in an ecological context by investigating patterns across space and phylogeny.MethodsWe applied untargeted Liquid Chromatography-Mass Spectrometry to examine the metabolomic diversity of the deep-sea coral,Callogorgia delta, across three sites in the Northern Gulf of Mexico as well as three other deep-sea corals,Stichopathessp.,Leiopathes glaberrima, andLophelia pertusa, and a shallow-water species,Acropora palmata.ResultsDifferent coral species exhibited distinct metabolomic fingerprints and differences in metabolomic richness including core ions unique to each species.C. deltawas generally least diverse whileLophelia pertusawas most diverse.C. deltafrom different sites had different metabolomic fingerprints and metabolomic richness at individual and population levels, although no sites exhibited unique core ions. Two core ions unique toC. deltawere putatively identified as diterpenes and thus may possess a biologically important function.ConclusionDeep-sea coral species have distinct metabolomic fingerprints and exhibit high metabolomic diversity at multiple scales which may contribute to their capabilities to respond to both natural and anthropogenic stressors, including climate change.
