Description
The marine ecosystem is threatened by rapidly changing climate change. Coral plays an important role in this marine ecosystem, such as providing shelter, food, and a place for reproduction of other marine life. In this regard, basic studies necessary for the preservation of coral living in Korea are insufficient, and studies related to larvae, the initial stage of occurrence of coral, are more insufficient. This study analyzed survival rates by incubating Chromonephthea hirotai larvae, a domestic habitat, under water temperature stress in a specific temperature section for 7 days, and analyzed differential expression genes (DEGs) and microbiome composition changes for those exposed to water temperature stress for 1 day in the control group 21°C and experimental group 26°C and 28°C. A total of 10,444 DEGs were annotated at least one for each database. There were 653 unique DEGs annotated at 21°C vs. 26°C, and 7,971 unique DEGs annotated at 21°C vs. 28°C. In both groups, 1,820 DEGs were shared and microbiome composition related to heat shock protein (Hsp) expressed by water temperature stress and immune-related gene expression were identified as the focus. This work was supported by Marine Biotics project (20210469) funded by Ministry of Ocean and Fisheries, Korea.
