title: [A review of the role and function of microbes in coral reef ecosystem].
abstract: Coral reef is consisted with several kinds of reef-associated organisms, including coral, fish, benthos, algae and microbes, which is an important marine ecosystem. Coral reef lives in the oligotrophic environment, has very highly primary productivity and net productivity, and is called "tropical rain forest in ocean". In corals, diverse microorganisms exert a significant influence on biogeochemical and ecological processes, including food webs, organism life cycles, and nutrient cycling. With the development of molecular biology, the role of microorganisms in a coral system is becoming more outstanding. In this article, we reviewed current understanding on 1) the onset of coral-bacterial associations; 2) the characteristics of microbes in coral (specificity, plasticity and co-evolution) ; 3) the role and signal regulation of microbes in the health and disease of coral; and 4) the response mechanism of microbes for global climatic change and consequent effects, such as temperature rise, ocean acidification and eutrophication. The aims of this article were to summarize the latest theories and achievements, clear the mechanism of microbial ecology in coral reefs and provide a theoretical reference for better protection and maintaining the coral's biodiversity.
