| Coral-associated microbes are the most basic and active components of coral reef ecosystem, which play an important role in coral reefs development, disease prevention, environmental adaptation, and so on. The community composition about these microbes changed significantly with the change of environments. However, more relevant researches for the composition and variation of function for these microbes have been limited because they are difficult to be cultured by artificial means. In this study, 54 scleractinian coral individuals from 6 coral reefs at different latitudes in the South China Sea were collected to investigate the diversity and composition of their associated bacteria based on 16S rRNA gene amplifiers using high-throughput sequencing. And the functional composition of these bacteria was predicted and compared by using PICRUSt tool. The results of alpha- and beta-diversity analyses (Ace values, which reflect community richness; Shannon index, which reflect community diversity; PCoA, principal co-ordinates analysis) showed that the distribution of bacteria exhibited significant regional differences for 6 different coral reefs, but little interspecific differences for different coral species. However, the functional genetic composition of these bacteria was similar, whether between different coral reefs or different coral species. These results provided insights into the ecological characteristics and functional composition of coral-associated bacteria in the South China Sea. More specifically, it first concluded that the functional composition of coral-associated bacteria was similar and stable, which may be used to characterize the health status of corals in different habitats. |
