Host Evolutionary Lineage Shapes Assembly, Network Topology, and Metabolic Potential of Coral Skeletal Endolithic Microbiomes.

ABSTRACT: Evolutionary history of the host may influence the skeletal morphology of scleractinian corals. However, its effects on the assembly and function of endolithic microbiomes remain unknown. We analyzed bacterial and archaeal microbiomes from the coral skeleton by using 16S rRNA gene sequencing. We collected the samples of seven coral genera distributed among the diverse "Complex" and "Robust" clades. In this study, bacterial α-diversity was significantly higher in the Complex clade relative to the Robust clade. Archaea, on the other hand, remained stable and showed no significant differences between the two host clades, and were most abundantly Nanoarchaeota and Thermoproteota. Analysis of the network topologies showed that network structures were different between the Complex group and the
