相关微生物群在水母的生命过程中起着至关重要的作用。本研究采用16S rDNA测序方法对4种常见水母毛刺Phyllorhiza punctata、Cyanea capillata、Chrysaora melanaster和Aurelia coerulea的内源性细菌群落进行了比较分析。从总共130 183个reads中收获了1049个otu。P. punctata和C. melanaster中丰度最高的门是Tenericutes（68.4%）和Firmicutes(82.1%)，而C. capillata和A. coerulea在变形菌门中丰度最高（76.9%对78.3%）。分类OTUs和细菌丰度从门到属水平显著下降。匹配前20位的属占群落总数的比例分别为：点状麻9.03%、毛毛麻48.9%、黑桫椤83.05%、蓝桫椤58.1%。前50个属的热图显示，蓝棘和毛棘的相对丰度远高于点状棘和黑桫椤。此外，共确定了41个KEGG水平2的预测功能类别。我们的研究表明，四种常见的剑虫科细菌群落具有独立的多样性，可能与寄主的代谢和环境信息处理有关。
Abstract The associated microbiota plays an essential role in the life process of jellyfish. The endobiotic bacterial communities from four common jellyfish Phyllorhiza punctata, Cyanea capillata, Chrysaora melanaster, and Aurelia coerulea were comparatively analyzed by 16S rDNA sequencing in this study. Several 1049 OTUs were harvested from a total of 130 183 reads. Tenericutes (68.4%) and Firmicutes (82.1%) are the most abundant phyla in P. punctata and C. melanaster, whereas C. capillata and A. coerulea share the same top phylum Proteobacteria (76.9% vs. 78.3%). The classified OTUs and bacterial abundance greatly decrease from the phylum to genus level. The top 20 matched genera only account for 9.03% of the total community in P. punctata, 48.9% in C. capillata, 83.05% in C. melanaster, and 58.1% in A. coerulea, respectively. The heatmap of the top 50 genera shows that the relative abundances in A. coerulea and C. capillata are far richer than that in P. punctata and C. melanaster. Moreover, a total of 41 predictive functional categories at KEGG level 2 were identified. Our study indicates the independent diversity of the bacterial communities in the four common Scyphomedusae, which might involve in the metabolism and environmental information processing of the hosts.
