The effects of ocean acidification on marine organisms are of increasing concern. Exopalaemon carinicauda is an important economic shrimp. However, little is known about the transcriptome data for shrimp in response to seawater acidification stress. In this study, the transcriptome of E. carinicauda in response to seawater acidification stress was recorded using the Illumina RNA-sequencing. A total of 59 990 unigenes from high-quality transcripts were generated. Of all annotated unigenes, 18 386 and 17 681 unigenes had significant matches with sequences in the NR, and GO databases, respectively. A total of 183 differentially expressed genes (DEGs) could be screened, of which 119 DEGs were up-regulated and 64 DEGs were down-regulated. KEGG enrichment analysis showed these DEGs were primarily enriched in the pathways of lysosome, carbohydrate digestion and absorption, apoptosis, and alpha-linolenic acid metabolism. These results indicate that seawater acidification stress leads to the activation of apoptosis and the activity of the energy metabolism system in order to resist the external environmental stress and ensure the continuity of the normal life metabolism, and thus the energy supply of the organism. These data will be helpful to further study the molecular mechanisms of shrimp resistance to seawater acidification stress.
