| Outline of Final Research Achievements |
The aim of this study is to comprehensively understand the metabolites inside and outside the coral and to highlight the factors that characterize stress tolerance. We conducted an integrated analysis of RNA-seq and metabolomic data from coral strains with different stress tolerance, and successfully extracted a group of functional genes and metabolites that may be related to stress tolerance. We established a new analytical platform, "PiTMaP", which enables high-throughput and direct metabolome analysis, and built a foundation for real-time metabolome measurement. As a result of nutrient loading experiments using coral polyps acquired during simultaneous mass spawning event and analyzed by PiTMaP, dozens of metabolites were identified that differed significantly depending on the presence or absence of zooxanthellae or stress.
