Metatranscriptomic Analysis of Corals Inoculated With Tolerant and Non-Tolerant Symbiont Exposed to High Temperature and Light Stress.

Algal symbionts of corals can influence host stress resistance; for example, in the Pacific Ocean, whereas (C-type) is generally dominant in corals, (D-type) is found in more heat-resistant corals. Thus, the presence of D-type symbiont likely increases coral heat tolerance, and this symbiotic relationship potentially provides a hint to increase the stress tolerance of coral-algal symbioses. In this study, transcriptome profiles of and -harboring (C-coral and D-coral, respectively) and algal photosystem functioning ( ) under bleaching conditions (high temperature and light stress) were compared.
