abstract：:Symbiodiniaceae are symbiotic dinoflagellates that provide photosynthetic products to corals. Because corals are distributed across a wide range of depths in the ocean, Symbiodiniaceae species must adapt to various light environments to optimize their photosynthetic performance. However, as few biochemical studies of ...
