从昼夜循环的角度来解释珊瑚-共生科的共生关系可能会为理解内共生的功能提供缺失的环节。在本研究中，我们发现了两种珊瑚全息生物（Acropora pruinosa-Cladocopiumsp.）的光生理、共生体细胞密度和基因转录。和poillopora damicornis-Durusdiniumsp.)有明显的昼夜振荡。与夜间相比，这两种珊瑚的光系统II最大量子产率在白天较低，但共生体科细胞密度较高。在白天，两种宿主体内与昼夜节律和共生相关的基因均上调，而与免疫相关的基因则下调。同时，两种共生体参与光反应、卡尔文循环和糖酵解的基因丰度较低，而参与NH4+同化的基因丰度较高。上述结果表明，白天共生菌科植物密度高可能与共生和氮代谢相关基因上调而免疫相关基因下调有关。此外,西娅。pruinosa-Cladocopiumsp。holobiont的昼夜振荡比p大。damicornis-Durusdiniumsp。从光生理、共生物科细胞密度和基因转录方面，揭示了物种特有的昼夜振荡。该研究为珊瑚全息生物适应昼夜环境变化的合作策略提供了有价值的见解。
Interpreting the coral-Symbiodiniaceae symbiosis in light of the day-night cycle may provide missing links in understanding the function of endosymbiosis. In this study, we found the photo-physiology, Symbiodinaiceae cell density and gene transcription of two coral holobionts (Acropora pruinosa-Cladocopiumsp. andPocillopora damicornis-Durusdiniumsp.) have clear day-night oscillations. These two coral holobionts showed lower maximum quantum yield of photosystem II but higher Symbiodiniaceae cell density at day-time, as compared to at night-time. At day-time, the genes related to circadian rhythm and symbiosis in both hosts were up-regulated, while those related to immunity were down-regulated. Simultaneously, both symbionts had lower abundances of genes involved in the light reaction, Calvin cycle and glycolysis, but higher abundances of genes involved in the NH4+assimilation. These results indicated the high density of Symbiodiniaceae at day-time might be attributed to up-regulating of genes involved in symbiosis and nitrogen metabolism but down-regulating of genes involved in immunity. Moreover, theA. pruinosa-Cladocopiumsp. holobiont had larger day-night oscillations thanP. damicornis-Durusdiniumsp. holobiont, in terms of photo-physiology, Symbiodinaiceae cell density and gene transcription, revealing species-specific day-night oscillation. This study provides valuable insights into the cooperation strategies of coral holobionts to adapt to the day-night environmental changes.
