Symbiotic Symbiodiniaceae mediate coral-associated bacterial communities along a natural thermal gradient.

ABSTRACT: The coral-associated microbiome plays a vital role in the holobiont, enabling coral adaptation to diverse environments by modulating its composition and mediating interactions among its constituents. However, the responses of coral microbiomes, particularly the interactions between Symbiodiniaceae and bacteria, to environmental changes remain unclear. To fill this knowledge gap, we examined Pocillopora acuta, an environmentally sensitive coral species, collected from three sites along the southeastern coast of Hainan which exhibit moderate environmental differences. We measured the physiological characteristics of Symbiodiniaceae and conducted amplicon sequencing to analyze the structure of Symbiodiniaceae and bacterial communities. Our results revealed that P. acuta in southeastern Hainan
