Abstract：
Coral polyps are composed of four tissues; however, their characteristics are largely unexplored. Here we report biological characteristics of tentacles (Te), mesenterial filaments (Me), body wall (Bo), and mouth with pharynx (MP), using comparative genomic, morpho-histological, and transcriptomic analyses of the large-polyp coral, Fimbriaphyllia ancora. A draft F. ancora genome assembly of 434 Mbp was created. Morpho-histological and transcriptomic characterization of the four tissues showed that they have distinct differences in structure, primary cellular composition, and transcriptional profiles. Tissue-specific, highly expressed genes (HEGs) of Te are related to biological defense, predation, and coral-algal symbiosis. Me expresses multiple digestive enzymes, whereas Bo expresses innate immunity and biomineralization-related molecules. Many receptors for neuropeptides and neurotransmitters are expressed in MP. This dataset and new insights into tissue functions will facilitate a deeper understanding of symbiotic biology, immunology, biomineralization, digestive biology, and neurobiology in corals.
摘要：
珊瑚息肉由四种组织组成；然而，它们的特征在很大程度上是未经探索的。这里我们报道了触手（Te）的生物学特征，肠系膜丝(Me),车身墙（Bo），和口咽部（MP），使用比较基因组，形态组织学,以及对大息肉珊瑚的转录组学分析，镰刀菌。创建了434Mbp的F.ancora基因组组装体。四种组织的形态组织学和转录组学特征表明，它们在结构上有明显的差异，原代细胞组成，和转录谱。组织特异性,Te的高表达基因（HEG）与生物防御有关，捕食,和珊瑚-藻类共生。我表达多种消化酶，而Bo表达先天免疫和生物矿化相关分子。许多神经肽和神经递质的受体在MP中表达。这个数据集和对组织功能的新见解将有助于对共生生物学有更深入的了解，免疫学,生物矿化，消化生物学,和珊瑚的神经生物学。
