表型可塑性被定义为个体基因型在暴露于不同环境条件时产生不同表型的特性。这种能力可以在行为、生物化学、生理和/或发育水平上表达，对物种的人口统计表现产生直接影响。在造礁珊瑚中，一个受到人类世全球变化严重威胁的群体，非遗传机制（即，表观遗传和微生物组变异）已被证明参与对环境变化的塑料生理反应。然而，这些机制相互作用的确切方式，有助于这种反应，以及它们的适应潜力仍然是模糊的。目前的工作旨在填补这一空白，通过使用多组学的方法来阐明的贡献和相互联系的机制调制的表型可塑性鹿角珊瑚（鹿角珊瑚）克隆受到不同的深度条件。结果显示脂质组，表观基因组和转录组的变化，但不是在共生和微生物群落。此外，一个潜在的转向更异养喂养行为的珊瑚在较深的网站证明。这些观察结果与珊瑚快速适应的多机制调制一致，强调了这一过程的复杂性和多因素方法的重要性，以告知潜在的干预措施，以提高珊瑚的适应能力。
Phenotypic plasticity is defined as a property of individual genotypes to produce different phenotypes when exposed to different environmental conditions. This ability may be expressed at behavioral, biochemical, physiological, and/or developmental levels, exerting direct influence over species' demographic performance. In reef-building corals, a group critically threatened by global change in the Anthropocene, non-genetic mechanisms (i.e., epigenetic and microbiome variation) have been shown to participate in plastic physiological responses to environmental change. Yet, the precise way in which these mechanisms interact, contribute to such responses, and their adaptive potential is still obscure. The present work aims to fill this gap by using a multi-omics approach to elucidate the contribution and interconnection of the mechanisms modulating phenotypic plasticity in staghorn coral (Acropora cervicornis) clones subject to different depth conditions. Results show changes in lipidome, epigenome and transcriptome, but not in symbiotic and microbial communities. In addition, a potential shift toward a more heterotrophic feeding behavior was evidenced in corals at the deeper site. These observations are consistent with a multi-mechanism modulation of rapid acclimation in corals, underscoring the complexity of this process and the importance of a multifactorial approach to inform potential intervention to enhance coral adaptive capacity.
