Introduction
Many microbes form symbiotic relationships with plants and animals. These relationships are complex and often persist throughout evolutionary time as organisms evolve in tandem. Some organisms are facultative symbionts, meaning that both partners can live independently while others are obligative, meaning that one cannot survive without the other. In obligative symbionts it is common that one organism provides necessary nutrients that the other organism is incapable of manufacturing. A unique obligative symbiotic relationship occurs between corals and their microalgal symbionts.
Corals are in the class Anthozoa and phylum Cnidaria. Species that live in the warm, clear waters near the equator are most well known, but species have also been found to live in deeper colder waters which are nearer to the poles.1 The clear waters near the equator are nutrient poor and coral do not have the resources to produce their own energy. The microbes in symbiotic relationships with the coral are endosymbiotic dinoflagellates. These dinoflagellates are single-celled algae in the family Symbiodiniaceae, and the most common dinoflagellates in tropical coral are of the genus Symbiodinium.
