Coral reefs serve an imperative role in the formation of marine ecosystems. They act as the foundation for complex food webs by supporting fish, sponges, algae, and invertebrates. However, coral bleaching and climate change have become major concerns in the conservation of ocean species over the past few decades. As a result, new methods of restoration are necessary for the propagation of these endangered coral species. This study focuses on the critical role that the symbiotic algae Symbiodinium, as well as their associated bacteria, play in the health of coral. A specific type of bacteria, α-proteobacteria, use virus-like particles called gene transfer agents as a method of diversification. This study indicates that the application of these gene transfer agents may increase the fitness of the coral holobiont’s associated bacteria. Coral degradation can perhaps be lessened if inhabiting microbiota can survive stressful conditions by diversifying their assemblage. This study attempts to understand the complex coral system by observing the effects of gene transfer agents on symbiotic algae as well as its associated bacteria.
