A study finds that the holobionts--assemblages of viruses, microbes, and their host macroorganisms--of coral and turf algae, which are major algal competitors of corals, interact through a distinct microbiome at the coral-algal interface; machine learning analyses suggest that the outcome of competition between holobionts is determined by the response of the interface microbiome to feeding derived from algal-produced metabolites, providing key insights into ecological interactions at the coral-algal interface, given that several reefs previously dominated by corals have been undergoing a shift toward turf algae dominance.
