Publication date: Available online 11 October 2018Source: Fish & Shellfish ImmunologyAuthor(s): Zhi Zhou, Zhaoqiu Liu, Lingui Wang, Jian Luo, Hailang LiAbstractGiant clams are one of the most important animals in coral reef ecosystem, and its growth and reproduction are being threatened by acute heat stress due to global warming. In the present study, the symbiont density, the crucial enzymes to physiological activities and the transcriptome were investigated in the outer mantle of giant clam Tridacna crocea after the acute exposure of high temperature. The density of symbiotic zooxanthellae decreased significantly during 12–24 h, with the minimum level (7.75 × 105 cell cm−2, p < 0.05) at 12 h after heat stress. The activities of superoxide dismutase in the heat stre...
