摘要： In aquatic ecosystems, the temperature of the water is an important ecological factor that modulates aquatic organisms' metabolism, growth, development, and reproduction. In this study, the morphological, transcriptomic, and metabolomic analyses of response of Marsupeneus japonicus to acute cold stress was investigated. The results revealed that low temperature caused profound morphological damage to the hepatopancreas. Transcriptomic responses suggested that energy and primary metabolism, cytoskeleton structure, and apoptosis signaling were altered. The metabolic responses to cold stress included changes of multiple amino acids and unsaturated fatty acids. Combined transcriptomic and metabolomic data indicated that energy metabolism pathways were downregulated in the hepatopancreas under cold stress. However, M. japonicus increased ATP and unsaturated fatty acids production to ameliorate. Moreover, cold stress caused significant attenuation of macrophage apoptosis. This study provides key information to increase our understanding of low-temperature tolerance in shrimp.
