AbstractThere is increasing evidence that ocean acidification (OA) has a significant impact on marine organisms. How ever, the ability of most marine organisms to acclimate to OA and the underlying mechanisms are still not well understood. In the present study, whole transcriptome analysis was performed to compare the impacts of short(7 days, named as short group) and long(60 days, named as long group) term CO2 exposure (pH 7.50) on Pacific oyster Crassostrea gigas. The responses of C. gigas to shortand long-term CO2 exposure shared common mechanisms in metabolism, membrane-associated transportation and binding processes. Long-term CO2 exposure induced significant expression of genes involved in DNA or RNA binding, indicating the activated transcription after long-term CO2 exposure. Oysters in the short-term group underwent significant intracellular calcium variation and oxidative stress. In contrast, the intracellular calcium, ROS level in hemocytes and H2O2 in serum recovered to normal levels after long-term CO2 exposure, suggesting the compensation of physiological status and mutual interplay between calcium and oxidative level. The compensation was supported by the upregulation of a series of calcium binding proteins (CBPs) and calmodulins (CaMs) related signal pathway. The results provided valuable information to understand the molecular mechanism underlying the responses of Pacific oyster to the acidified ocean and might have implications for predicting the possible effects of global climate changes on oyster aquaculture.
