| Symbiodinium spp. is the essential symbiont in corals, providing the host with vital photosynthesis product. In the past decades, global warming and anthropogenic activities has become the major threats to cause coral bleaching events which is attributed to the expulsion of symbionts. There is evidence that availability of trace metal to symbiont is linked to the coral anti-stress capacity, because they are cofactor required by antioxidative enzymes. In this study, we applied RNA-seq to generate a general gene expression profile of S. kawagutii, cultured under different trace metal concentration. Five trace metals Fe2+, Zn2+, Cu2+, Mn2+, Ni2+, were examined in this work. The aim of this study is to provide insights to interpret how trace metal availability modulate the gene transcription, metabolism network, and the antioxidant capacity of Symbiodinium.
