Metagenomic insights into jellyfish-microbe interactions during metamorphosis

The exploration of jellyfish microbiomes may shed light on the ancestral mechanisms and evolutionary trajectories of metazoan-microbe associations and interactions during metamorphosis. However, current knowledge on functional features of jellyfish microbiomes remains limited. Here, we performed genome-centric analysis of associated microbiota across four successive life stages (polyp, early strobila, advanced strobila, and ephyra) during strobilation process in the model species Aurelia coerulea.

对水母微生物组（jellyfish microbiomes）的研究，可为阐明后生动物-微生物共生关联与互作在变态发育过程中的祖先机制及演化轨迹提供重要依据。然而，当前学界对水母微生物组功能特征的认知仍较为有限。本研究以模式物种Aurelia coerulea为对象，对其横裂生殖过程中4个连续生命阶段——水螅体（polyp）、早期横裂体（early strobila）、晚期横裂体（advanced strobila）及碟状体（ephyra）的共生微生物群开展了以基因组为中心的分析。
