水母6.5亿年进化成功的关键是适应性：水母的底栖和远洋世代交替，有性和无性繁殖模式，多种体型和世界性分布，水母很可能已经建立了丰富的微生物群落。在这里，我们探索了脊椎动物水母金鱼的细菌组合(1832课)。研究了通过包囊繁殖所涉及的生活阶段，即母息肉、其休眠包囊(足囊)和新近从足囊中剥离的息肉(不包括包囊)。使用MiSeq Illumina 16S rRNA基因V1V2区域的配对末端标签测序来评估相关细菌组合。在所有被调查的生命阶段都发现了一个微生物核心群落，包括已知是碳、氮、磷和硫循环的关键驱动因素的近亲细菌。此外，Plocamia核心细菌的一半也存在于水母的生活阶段，这表明这种细菌群落可能代表了水母的固有特征，有助于它们的进化成功。
The key to 650 million years of evolutionary success in jellyfish is adaptability: with alternating benthic and pelagic generations, sexual and asexual reproductive modes, multitudes of body forms and a cosmopolitan distribution, jellyfish are likely to have established a plenitude of microbial associations. Here we explored bacterial assemblages in the scyphozoan jellyfish Chrysaora plocamia (Lesson 1832). Life stages involved in propagation through cyst formation, i.e., the mother polyp, its dormant cysts (podocysts), and polyps recently excysted (excysts) from podocysts – were investigated. Associated bacterial assemblages were assessed using MiSeq Illumina paired-end tag sequencing of the V1V2 region of the 16S rRNA gene. A microbial core-community was identified as present through all investigated life stages, including bacteria with closest relatives known to be key drivers of carbon, nitrogen, phosphorus, and sulfur cycling. Moreover, the fact that half of C. plocamia’s core bacteria were also present in life stages of the jellyfish Aurelia aurita, suggests that this bacterial community might represent an intrinsic characteristic of scyphozoan jellyfish, contributing to their evolutionary success.
