Comparative chromatin dynamics reveal differential thermal tolerance mechanisms between two congeneric oyster species
Oysters, being globally farmed bivalve of significant economic and ecological value, are increasingly confronted with heat stress induced by global warming, such as the frequent occurrence of mass summer mortality events worldwide. The role of epigenetics in adapting to high-temperature environments...

Oysters, being globally farmed bivalve of significant economic and ecological value, are increasingly confronted with heat stress induced by global warming, such as the frequent occurrence of mass summer mortality events worldwide. The role of epigenetics in adapting to high-temperature environments has garnered growing attention; however, its application in oysters remains poorly understood. In this study, we conducted a comparative analysis between two closely related oyster species (the relatively thermosensitive Crassostrea gigas and the relatively thermotolerant Crassostrea angulata) using ATAC-Seq and RNA-Seq to reveal the differential thermal tolerance mechanisms at the chromatin dynamics level in response to high-temperature stress. The comparative analysis showed that the inhibitor of apoptosis protein (IAP) family and its associated apoptosis pathways were the major divergent pathway between the two species.
