Abstract:
Coral Symbiodiniaceae and bacteria maintain a symbiotic relationship that is essential for coral survival. The symbiotic communities component in the polyps host could affect coral resistance and the ability to recover from stress. In this study, we increased the cultured range temperature (۲۶ ± ۱ ℃) of Sarcophyton trocheliophorum and Euphyllia ancora at ۳۲ ℃ for ۱۲ hours, and then amplified the ITS۲ sequence of Symbiodinium and the bacterial ۱۶S rRNA sequence in the sample, respectively to compare Symbiodiniaceae and bacteria diversity and abundance with normal culture temperature. The results showed that there was no change in the dominant species of Symbiodinium in these two corals in the heat treatment group, but the diversity of Symbiodinium in the two corals was significantly different. On the other hand, after thermal treatment, the endophytic bacteria of S. trocheliophorum represented more aerobic bacteria Delfitia, while the E. ancora was infected with more pathogenic endosymbiotic bacteria. This difference observation can be attributed to the different tolerance of corals.
