Insights into the occurrence of phylosymbiosis and co-phylogeny in the holobionts of octocorals from the Mediterranean Sea and Red Sea
Abstract Background Corals are the foundational species of coral reefs and coralligenous ecosystems.Their success has been linked to symbioses with microorganisms, and a coral host and its symbionts are therefore considered a single entity, called the holobiont.This suggests that there may be evolutionary links between corals and their microbiomes.
