Popis: | Fat greenling (Hexagrammos otakii) is an important aquaculture fish species in northern China. Unfortunately, Vibrio infections have caused considerable losses to the fat greenling aquaculture industry. However, the study on immune response of fat greenling against Vibrio species has not been reported yet. In this paper, the immune response of fat greenling against V. harveyi at gene expression level was studied by transcriptome analysis. A total of 189753 high-quality unigenes with a N50 length of 672bp were obtained by transcriptome profiling, which provided abundant data for the future study of fat greenling. Comparative analysis showed that 5425 differentially expressed genes (DEGs) were identified on day 3 post-infection (3dpi), containing 1837 up-regulated and 3588 down-regulated genes. Further annotation and analysis revealed that the DEGs were enriched in complement and coagulation cascades, ribosome, oxidative phosphorylation, glycine, serine and threonine metabolism and peroxisome proliferator-activated receptor (PPAR) signaling pathway. These pathways were mainly associated with phagocytosis and pathogen clearance, rarely involved in bacteria adhesion and pathogen identification, which suggested that the host might begin to clear and kill the invading bacteria on 3dpi. The research might provide a valuable resource to further study immune response and suggest strategies against V. harveyi infection in fat greenling. |
