| Abstract： | As one of the piscine rhabdoviruses, Siniperca chuatsi rhabdovirus (SCRV) has caused considerable losses to mandarin fish aquaculture industry. RNA-seq, as efficient transcriptome research method, has been widely used to study the immune response of fish to pathogens. This study reported the effect of SCRV infection at 0, 24 and 60 hr on S. chuatsi at the transcriptome level. A total of 61,527 unigenes with high quality were obtained, and 3,095, 1,854 and 227 differentially expressed genes (DEGs) were labelled between the Sc24 and Sc0 groups, the Sc60 and Sc0 groups and the Sc60 and Sc24 groups, respectively. Genes involved in innate and adaptive immunity were highlighted. In Gene Ontology analysis, the DEGs that participated in immune response, innate immune response and the regulation of apoptotic process were identified as enriched classes. Kyoto Encyclopedia of Genes and Genomes pathway results indicated that most DEGs caused by SCRV infection were identified in the immune system (retinoic acid-inducible gene-I-like receptor/Toll-like receptor/nucleotide-binding oligomerization domain-like receptor/C-type lectin receptor signalling pathway), cellular processes, cell growth and death (p53 signalling pathway, cellular senescence, apoptosis and phagosome), and metabolism. Quantitative real-time PCR was used to further verify the expression levels of 15 immune-related DEGs. The transcriptome database obtained in this study provided further in-depth insight into the immune response of S. chuatsi against SCRV. |
