Abstract:

Mud crab (Scylla paramamosain) is an important economic species in China. Vibrio parahaemolyticus infection have caused a great economic loss in mud crab farming. The mechanism involved in the immune responses of mud crab to V. parahaemolyticus is unclear. In this study, the physiological and immune response to V. parahaemolyticus infection were investigated in S. paramamosain. The results showed that V. parahaemolyticus infection decreased total hemocyte counts, led to cytological damage, and caused high mortality. Transcriptome analysis showed that 1327 differentially expressed genes (DEGs), including 809 up-regulated and 518 down-regulated ones, were obtained after V. parahaemolyticus challenge. These DEGs were mainly involved in the immune response and infectious disease. Additionally, transcriptome analysis revealed that Toll, immune deficiency (IMD), and prophenoloxidase signalling pathways played essential roles in antibacterial immunity against V. parahaemolyticus infection in mud crab.

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
