Figure 1: Bacterial community composition of deep-sea corals and seawater from the Red Sea on the bacterial family level (Greengenes database, bootstrap ≥60).

Pie charts denote average bacterial abundance across replicates for the three coral species. The taxonomy bar plot denotes relative bacterial abundance across species replicates and seawater. Each color represents one of the 12 most abundant families (overall sequence count) in all samples. All other taxa are grouped under category ‘others’.
